parking lot maintenance
Wisconsin has nearly perfect weather in early fall. Daytime temps in the 70s mean that just about every activity is comfortable. Temperatures in the 50s at night make for great sleeping weather. These gorgeous conditions can almost convince us that it will last forever. But we know it won’t.  Whether or not there’s another polar vortex in our future this winter, we know it will get cold. There will be snow and ice. There will be salt and sand. It will be messy. It’s time to think about parking lot maintenance.
 
As difficult as it is to think about, now is the time to prepare for winter. To make it easier for you, we’ve developed this handy checklist of everything you need to address to protect your parking facility before Wisconsin does what Wisconsin does. 

Winter Preparation Checklist

The Autumn list for parking lot maintenance includes:
  1. Clean your parking lot. Leaves are not as innocent as they seem. Their chemical composition can  damage the surface of your concrete or asphalt. In addition, fall leaves that have been compacted and frozen by an early snowfall are a pain to remove. A professional sweeping will clear leaves and debris from places where water needs to flow freely. Then, pressure wash the entire facility for clean, odorless property.
  2. Inspect thoroughly for damage. Perform repairs on potholes or cracks. If you defer these repairs until the spring thaw, the damage will be greater and more expensive to fix. 
  3. Check your drainage so water doesn’t pool in the lot or run back to the foundation.
  4. Seal your concrete. Concrete sealing creates a barrier between winter chemicals and salt and your parking surface. By the end of October, seal coating season is just about over, so don’t delay.
  5. Walk around all your snow plowing routes to ensure that they are unobstructed.
  6. Evaluate whether or not your pavement markings and signs are clear and easy to see. If not, consider new parking lot striping. A freshly painted lot  increases the odds that people will drive and park safely. When large sections of your parking lot are used to store unmelted snow, you need to make sure that the rest of your parking lot can be used properly and efficiently.
  7. Review all customer and employee access points into your building. wash to make sure that people don’t slip and fall. check for irregularities in the walkway that can cause people to trip.
If you fail to winterize, your costs could easily shift from preventative (which is less expensive) to reparative (which is more expensive).
 
Start today! The average first frost in southeastern Wisconsin happens in October. That’s now and it means you want to schedule your service within the next few weeks. Before we perform any job for our Milwaukee clientele we map out a detailed plan to ensure that the work is done efficiently and expertly. Call us today at (414) 774-0884 to schedule your winterizing services.
 
professional power washing
We write a lot about power washing on our blog because it gives your property more bang for the buck than almost any other monetary investment. Also known as pressure washing, it gives you a deep clean you can’t get any other way. It removes accumulated layers of dirt and grime, no matter how long it has been since your property was last sparkling clean. Power washing can be used on pavement, walls, roofs, and equipment.
 
Deep, ground-in dirt can come from a variety of sources including natural elements, such as the weather, and the human presence on your property. This kind of dirt won’t disappear by itself. The longer you go without a deep clean, the more difficult it becomes to get it looking like new again.
 
Professional power washing is an important part of all property maintenance. If you’re a smaller business, you might be tempted to do it yourself, but that will likely be frustrating and a waste of time. If you’re a larger business it’s easy to forget to schedule this type of routine maintenance. But you don’t want to be “that” business: the one with the dingy exterior that stands out in a bad way. 
 
In our travels around greater Milwaukee, we’ve observed 8 businesses that need more pressure washing than they currently have scheduled.
  1. Warehouses. We know that warehouses are places where work happens which is why regular power washing of walkways, loading docks, and entryways should be a given. On top of that, there is the cleaning that needs to be done in between tenants. This should include pre-treating stains and spills, removing oil and grease, and sealing the concrete. 
  1. Retail centers and shopping malls. Since these facilities welcome paying guests year-round, we are always surprised when we see that exterior cleaning has been neglected. Shopping centers require parking lot maintenance that includes frequent pavement cleaning. 
  1. Restaurants and hotels. If guests notice that exterior areas have been allowed to get dirty, what impression will that give them of the interior areas? The entrance, walkways, and parking lots are the most obvious place to start, but don’t forget that dirty dumpster area. A professional power wash will give you the satisfaction of cleanliness and keep your guests’ minds on their delicious meal or their good night’s rest. 
  1. Entertainment complexes. The remnants of people having a good time — such as peanut shells, gum, and anything with sugar in it — usually end up on the grounds outside the venue. After a few weeks of baking in the sun, only a professional power washer will be able to remove them completely.
  1. Office buildings. Most property managers know that their office buildings need regular pressure washing. Still, it’s surprising how long cigarette butts, empty beverage containers, spider webs, and last autumn’s leaves can stay put. For heavily trafficked areas, power washing should be done monthly.
  1. Apartment complexes. There are so many places in a residential community that can and do get dirty. Parking areas, stairways, and common areas are easily littered. If left too long, residential dirt has a compound effect because it’s human nature to assume that if other people are lazy with litter, you can be too. When your business is to attract renters, you want your property looking like new.
  1. Trucking centers. Most logistics centers and truck fleets are housed outdoors where they are subject to the whims of the weather. In these cases, the trucks need regular power washing as much as the facility does.
  1. Gas stations. Most modern gas stations also have a decent sized convenience store that serves snacks, soda, and fried foods which are frequently spilled on the way to the car. Then there is the oil from the constant vehicle traffic. And if the station has a car wash, there is potential for even more dirt to accumulate on the property. Regular professional cleaning is the answer here too. Your customers will notice.
Professional power washing must be frequent, thorough — and most of all — scheduled. Give us a call to set up your regular pressure washing services today. We’ll work around your schedule so that your business isn’t interrupted. And you’ll be very proud of your property.
pavement marking communicates

Do you realize that your pavement marking can talk? Well maybe not talk exactly, but it certainly can communicate. In fact, that is its primary function. It’s like the project manager on your team or the traffic officer at Miller Park. Fresh, high quality pavement marking keeps vehicle and pedestrian traffic organized and moving smoothly which keeps everyone safer and happier.

What Is The Purpose of Marking?

Pavement marking is so ubiquitous and so expected that most people rarely give it a thought — until it isn’t visible when they need it. If you have ever been caught in a blinding thunderstorm or found yourself with seconds to decide if you need to merge or stay put, you know that proper road surface marking is the difference between fear and confidence. 

The Manual on Uniform Traffic Control Devices (MUTCD) published by the U.S. Department of Transportation says, “Pavement markings are used to convey messages to roadway users. They indicate which part of the road to use, provide information about conditions ahead, and indicate where passing is allowed.” Symbols, such as for bicycles, tell you how you are permitted to use the lanes. They can also warn you of areas where you might want to exercise caution, such as at railroad crossings.

In parking structures and on other private property, clear easy-to-understand striping tells drivers where to go and what to do. A prominent crosswalk tells pedestrians that it is safe to walk there. Signs and symbols tell both foot and vehicle traffic where they are permitted to move, wait, and park. This is good for customers and business, but it also complies with the law, specifically in regard to the Americans with Disabilities Act (ADA). When creating handicapped parking areas, a combination of clearly marked stalls and proper signage sends a warm welcome message to all visitors.

What Do Parking Lot Pavement Markings Mean?

When you enter a ramp or other parking structure, you are confronted with markings that are more complex than the standard yellow and white of the highways. Pavement marking works in conjunction with signs and (sometimes) traffic signals to direct traffic through a parking area and a yellow line (either solid or broken) is still used to indicate two-way traffic. However, you will also see stop lines, crosswalks, painted curbs, and symbol markings. 

  • A stop bar marking is a single white line that tells you where to stop.
  • Word and symbol markings, such as yield or directional arrows, communicate to you without diverting your attention from the road.
  • Crosswalk markings are parallel double white lines that tell pedestrians where they can cross the roadway. Sometimes they are accompanied by the symbol “ped xing” on the road just before the crosswalk that tells the driver to prepare to stop.
  • Curb striping is used to communicate curb use rules such as no parking, fire lanes, handicapped zones, loading and unloading, parking for a short period of time, and parking allowed.

$136M Pavement Marking Project

In California, they tested a new 6-inch wide, highly reflective road striping in 2017. The $136 million project was implemented on I-80 in the capital city of Sacramento. The test was so successful that Caltrans decided to re-stripe 50,000-plus lane miles of state highway system in the next decade. 

Their reasoning is that markings “must be capable of conveying information during inclement weather and evening hours when there may be little to no illumination from overhead lighting. The 6-in.-wide striping provides a valuable continuous stream of information about the roadway that signs or signals cannot supply. They alert drivers to changes in the roadway and help them maintain their position inside of the lane without requiring the driver to take their eyes off the road.”

While pavement marking obviously can’t talk, it does tell us things and communicates valuable information that we literally cannot live without. If your striping is faded or inefficient, give us a call. We’ll have it “talking” to you again in no time.

DIY Pressure Washing
DIY pressure washing is quite the fad. Lots of people think they can tell you how to safely use a pressure washer to clean your property. After all, you’re spraying water. How hard can it be?  Not hard at all according to HGTV and DIY Network. “The process only requires a few tools”, they say. “You can purchase a pressure washer at nearly any hardware store or rent one from a local tool rental shop”, they insist. “Erase years of wear and tear from your driveway in just a few simple steps”, they promise. Be skeptical, we advise.
 

It Looks Easier Than It Is

 
Pressure washing is one of those things that looks much easier than it actually is. Without experience or someone to show you what to do, you won’t be certain of the outcome of your first efforts with the pressure washer. When you operate a pressure washer incorrectly, you run the risk of property damage, physical injury, and environmental pollution. If you use too much pressure for too long in a small area, you will have etched concrete. If you don’t know what safety precautions to take or if you give into the temptation to take safety shortcuts, you can end up in the emergency room. Indiscriminate, unplanned washing can send pollutants into the municipal water system or your carefully tended garden.
 
Even people who have experience with professional power washing equipment are tired and dirty at the end of the job. When you consider the expenses of DIY pressure washing — machine rental, cleaning supplies, potential damage repair — and the amount of time the work will take, you have to consider the return on investment. It’s especially tempting for small business owners with modestly-sized properties to think that they can save some money by going the DIY route. But, wouldn’t the time you spend learning pressure washing the hard way be better spent investing in the business you own — the place where you are an expert?
 
At Wahlen Works, we are experts in pressure washing so we do have a dog in this hunt. We think you are going to be happier and better off if you hire us to do your pressure washing rather than doing it yourself. And we are not the only ones who urge potential novice pressure washers to be cautious. Glenn Hegge of the “Handyman Show” says, “While a power washer often is the tool of choice for driveways, decks and siding, you have heard me caution about using a power washer for certain projects, because the water pressure these units create can damage the things you are trying to make look good.”
 

Pressure Washing Pitfalls

 
We have observed five common areas where inexperienced pressure washing gets people into trouble. Each one provides a good reason not to undertake DIY power washing. 
 
  1. Using too much pressure. Water pressure is measured in pounds per square inch (psi). The water pressure of a typical garden hose is about 40 psi, while a gas-powered pressure washer dispenses water at between 2000 to 2800 psi (source: consumer reports). This is enough pressure to splinter wood, dent automobiles, and etch concrete. Without experience, it’s easy to cause damage that is expensive to fix.
  1. Working inefficiently. Most 1950’s housewives would tell you that it’s best to clean top to bottom and back to front. They would probably also tell you to soak tough stains and air dry your sheets. The same principles apply to pressure washing. However, if you aren’t accustomed to this mindset, you might not think to pre-treat grease stains until they didn’t get clean the first time. 
  1. Not using the correct products. Speaking of pre-treating, do you know which solutions to use? Or which detergents to add to the water? Or that you need to add cleaning solutions to the water at all? If not, don’t feel bad. Most people don’t. This is where a professional can save time and money by doing the job right the first time. In addition, they know how to keep harmful chemicals out of the sewer system and out of your landscaping.
  1. Not using the correct equipment. There are many different types of pressure washers available for rent and for purchase. Generally speaking, electric units have a lower psi and gas units have a higher psi. Beyond that, it takes some time to research and decide which machine you need. Or you can take the word of the salesperson. All of these things take time and have a learning curve. 
  1. Failing to take proper safety precautions. If your pressure washer can etch concrete, what do you think it will do to your Nike’s? You need the right protective equipment which includes sturdy shoes, protective eyewear, and gloves. If you are using a gas powered machine you shouldn’t operate it in an enclosed space. If you are using an electric machine you need to remember that water is an excellent conductor of electricity. In other words, if you’ve never operated a pressure washer before, there’s a lot to learn. Most of it is probably in the manual, but how much of that will you realistically read?
 
Properly maintained hardscapes add value to your property and speak well of your business. And yet, your time is most valuable when it’s invested in what matters most to you. Instead of spending your Saturday learning how to use a pressure washer, be a DIY outdoorsman and let the facilities professionals keep your facility clean.
seal your concrete
Anyone who has ever tried to maneuver through a parking structure which is in the middle of extensive repairs knows that it’s bad for business. Drivers going opposite directions need to share the same lane when they can’t see around the corner. Dust, debris, and muddy water coat their clean cars. The noise is deafening. And they still have to pay to be there.
 
As bad as it is on visitors, imagine how much worse it must be for the property owner who has to shoulder the burden of the expense and apologize to customers. We’re not saying that sealing your concrete means you never have to make repairs. But we are saying that you can greatly lengthen the period of time in between repairs when you seal your concrete.
 

In this blog post we will look at the three most important reasons to seal your concrete.

 
First, as mentioned above, sealed concrete lasts longer. The sealant keeps chemicals and water from penetrating the concrete. At Wahlen Works, we use a top of the line silane sealer [https://www.wahlenworks.com/sealing/] which improves resistance to deicing salts, reduces dirt penetration, and will not degrade when exposed to the sun’s UV rays. This in turn reduces the risk that the rebar within the concrete will corrode. “Silane is the smallest molecular compound of commonly available penetrating sealers. Chemically, Silane forms a covalent bond within porous masonry that clots surface pores. Silane…will only wear away if the concrete surface itself wears away. Noted for very low viscosity, silane is frequently used for sealing dense concrete, such as parking decks, concrete facades, and dense brick…It can be used on parking surfaces, bridges, roadways, runways, curbs, and other concrete surfaces.” [https://en.wikipedia.org/wiki/Concrete_sealer]
 
Second, a sealed concrete surface is much nicer looking, which speaks well of your business. And sealed concrete retains its professional appearance longer than unsealed concrete. If you’ve ever tried to park in a location where the pavement striping is almost completely faded away or there are holes in the parking surface, you know what we mean. As a property owner who cares about the impression you make to your visitors and the community, you want to ensure that your concrete is sealed on a regular basis. 
 
Third, sealed concrete resists staining. In the summer stains can come from ice cream, soda pop, and melted candy. In the winter stains come from salt, sand, and melted ice. Oil, grease, and chewing gum are problems year-round. Without proper sealing, these stains can permanently mar the surface of your concrete, making it look old before it’s time. As an added bonus, sealed concrete is much easier to clean than a non-sealed surface, saving you time and money.
 
If your concrete surfaces haven’t been given their proper attention in awhile, start with a thorough sweep and pressure wash. After pressure washing, preserve your facilities by sealing your concrete. In addition to the long-term savings, we will ensure that you enjoy short-term savings as well by creating a package deal that meets your needs on your schedule.

Concrete has made the modern world

The importance of concrete can’t be overstated. It is the most widely used man-made material on the planet.

A recent blog post by Bill Gates is titled, “Have You Hugged a Concrete Pillar Today?” He quotes Vaclav Smill who “argues that the most important man-made material is concrete, both in terms of the amount we produce each year and the total mass we’ve laid down. It is the foundation (literally) for the massive expansion of urban areas of the past several decades, which has been a big factor in cutting the rate of extreme poverty in half since 1990.”

What is Concrete?

According to the University of Illinois Department of Materials Science and Engineering, concrete is a composite material which is made up of a filler and a binder. The binder (cement paste) “glues” the filler together to form a synthetic conglomerate. The constituents used for the binder are cement and water, while the filler can be fine or coarse aggregate… It is important to distinguish between cement and concrete as they are not the same.”

Cement is not used on its own. When it’s mixed with fine filler you get mortar for masonry. When it’s mixed with coarse sand and gravel you get concrete. Another key piece of the equation is water. The amount of water you use determines the strength of the aggregate. “Low water to cement ratio leads to high strength but low workability. High water to cement ratio leads to low strength, but good workability.” It can be further strengthened by adding rebar – reinforcing steel bars.

Strengths and Weaknesses

Concrete is strong enough to bear the heavy load of a skyscraper without compressing. It can resist the pressure of water behind a dam. It can support thousands of cars, trucks, and busses on a bridge. There is a reason that concrete structures from the Roman Empire still exist.

Concrete can also deteriorate. In places like Wisconsin, where the temperatures drop below freezing every year, water from snow and rain can penetrate its surface. The water expands about 9% in volume as it freezes. When it melts during warmer weather it causes the material to weaken over time. Concrete also deteriorates when exposed to certain chemicals such as acids which are present in spills, or salts and alkalis which are used to treat driving surfaces in winter.

At Wahlen Works, we know concrete. We understand it’s properties and we know how to preserve it. The surface needs regular washing to remove acids, salts, and alkalis. It needs to be sealed once every five years or so. We are ready to bring our expertise to your unique property challenges and save you money over the long-term.

Concrete Trivia

  • The first concrete street in America was built in Bellefontaine, Ohio in 1891.
  • The heaviest concrete structure in the world today is the Three Gorges Dam in China, which opened in 2003. It weighs 144,309,356,753.51 pounds. 
  • In 1819, the first known parking garage was built for the Hotel La Salle in Chicago. 
  • The Pantheon in Rome has the world’s largest unreinforced concrete dome. 
  • In the modern world, only water is used more than concrete.
Spring cleaning for parking structures and garages

Spring has officially arrived! One of the first things we recommend you do is go outside and take a look at your parking structures and garages. Are they gray and dusty? Is there an unpleasant accumulation of sand and salt? Have the markings on the pavement faded? Has trash been blown into the corners? If so it’s time for spring cleaning. If the debris and chemicals and sand aren’t disposed of properly, you risk damaged concrete and clogged drains.

Your concrete needs regular cleaning and preventative maintenance to prolong the life of the surface and save money on expensive repairs. But it especially needs a deep clean after one of our long midwestern winters. Located in the middle of the “Winter Facts” page on the Wisconsin DOT website is a list of some the materials they use to treat roads for snow and ice: calcium chloride, magnesium chloride, salt brine. Property owners should remove and dispose of pollutants properly for structural preservation. This maintenance also maintains an aesthetically pleasing appearance and prevents environmental damage. Engaging in prompt clean-up will also reduce the risk of injury to pedestrians who might slip on accumulated dry sand.

Spring Cleaning List

The spring cleaning list for parking structures and garages includes:

  1. A thorough sweeping to remove trash, sand, salt, and any leftover leaves from last fall.
  2. Pre-treating stains from oil spills, beverage spills, and other dirt deposits.
  3. Professional power washing with a high pressure nozzle to deep clean the paved surface and lift out all of the dirt.
  4. Re-marking of faded parking stall lines, pedestrian walkways, and directional arrows.
  5. Concrete sealing to protect your surfaces from water, chemicals, and traffic wear-and-tear.

Once each of the items above is checked off, it’s time to think about ongoing maintenance. Some facilities, such as hospitals, have a high volume of traffic and high turnover in the parking areas. Dirt and debris accumulate much faster than in a structure, such as an apartment, that doesn’t see as many vehicles entering and exiting. A high volume facility may require monthly sweeping while a low volume facility may only need two to three maintenance sweeps a year.

Spring Cleaning Service Package

Spring is a great time to consider a complete service package for your property. Service packages include sweeping, power washing, pavement striping, concrete sealing, and ongoing maintenance. This type of package offers the greatest value to the business owner. At Wahlen Works the cost is significantly less than if the services were purchased separately. We can create contracts for time periods between one to five years so that you can plan and budget accordingly. Longer term contracts lock in current pricing and save the headache of having to address the same issue year after year.

Don’t hire a novice. Our knowledge of equipment, processes, and chemicals will ensure that your parking facility maintains a clean, professional appearance at all times. We provide our services on your schedule so that your business isn’t disrupted and we guarantee outstanding results. Contact us today to schedule an appointment that fits with your schedule. https://www.wahlenworks.com/estimate/

new parking lot striping

If you’re a commercial property owner, a parking lot with freshly painted, clearly marked lines is almost as good as the smell of a brand new automobile. But that freshly painted look is hard to remember after a long winter of snow and snowplows, when your parking lot striping is as faded as a ten-year old car. In addition to the pleasure of a new-looking lot, your customers’ convenience and safety depend on the clarity and visibility that a professionally striped parking lot provides.


So how do you get that “new car feel” for your old parking lot?


First, you want to ask yourself a few questions. “Does the traffic flow make sense to my visitors?” “Is the space used as efficiently as it could be? Am I compliant with all applicable regulations?” “Do I have enough upright signage for stopping, yielding, and pedestrian crossing?” “Can pedestrian walkways be clearly seen?” If the answer to any of the above questions is no, it’s time to restore your parking lot to it’s original showroom look.


Fresh parking lot striping will provide you with clearly marked parking stalls and bright, durable pavement marking. This means professional quality, crisp lines measured precisely and painted to the required thickness. It includes pedestrian walking spaces, directional driving arrows, entrance and exit signs, handicapped parking spaces, loading and unloading areas, and unmistakable fire lane areas. In some instances, such as handicapped spaces and fire lanes, there must also be both marking on the pavement and on upright signs. 


Whether it is brand new asphalt, freshly seal coated, or existing lines that need to be re-painted, we do it all. We have the equipment and personnel to complete the work in your off hours so we do not interrupt your operations. Restoring your parking lot to it’s original shine has never been easier. 

For a complete parking lot remodel, ask about including our power washing and concrete sealing services along with your parking lot striping job. You’ll be proud of your property once again. 

Eco-Friendly Process

According to Greg Neiderer, Principal and Director of Restoration for Walker Consultants, a leading parking consultant in the United States, “Some parking facility owners and operators believe that as long as their structures continue to serve the public, few maintenance-related tasks need to be performed. Nothing could be further from the truth.” In a case study of three Pennsylvania garages, Neiderer shows that the one with the most comprehensive maintenance history had the lowest cost per space per year.


Proper parking structure maintenance reduces premature deterioration and future operating costs. An important part of this ongoing maintenance is the cleaning and washing of concrete surfaces. Concrete is a porous surface that can absorb oil and other liquids like a sponge. Chloride contamination caused by deicing salt contributes to deterioration of the concrete as well. These substances need to be removed regularly. Professional pressure washing produces a deep, uniform clean that is both cost-effective and aesthetically pleasing. 


At Wahlen Works we specialize in full-service commercial pressure washing for businesses that have high standards of property maintenance and cleanliness. We accomplish this with a thorough, detailed four-step cleaning process that consistently provides superior pressure washing results.

  • First, we thoroughly go over the entire facility with pre-treating chemicals which are all biodegradable. We treat oil spots, beverage stains, and other dirt deposits. 
  • Second, we apply phosphate free, professional grade detergents to the entire surface of the garage. 
  • Third, we detail every square inch with a high pressure nozzle, providing a deep clean to lift out all of the dirt. In contrast to the surface cleaning used by some other companies, this is a close application to blast all the dirt out.  
  • Fourth, we drain the waste water. We use polypropylene filters over the drains which pull oil from the water and prevent debris from washing into the sewage system. At the end, we pick up everything and dispose of it properly. If your property requires waste water recovery, we provide that service at this time. 

When you hire Wahlen Works, you are investing in the longevity and appearance of your property. In addition to reducing overall operating costs, your facility will look better and make a better impression on visitors.

parking lot striping machine

Caring for your parking lot or garage is a huge component of building maintenance. As mentioned in a previous post, it influences the first impression your customer has when they arrive at your facility. At Wahlen, we have over 40 years of experience keeping parking lots and garages in tip top shape and recommend the following schedule.

As often as needed:

The first step to keeping a lot or garage clean is to ensure the pavement is kept free of debris. Whether you manage a lot or garage, we recommend you have your pavement swept as often as you feel the need to. If you manage a lot, we definitely recommend doing a sweep after the leaves have fallen in the fall, before the first snowfall, and after winter once the snow has melted. While we love the changing colors of fall, once fallen leaves begin to deteriorate they can make your lot appear dirty. Similarly, a sweep and clean before winter can help ensure fallen snow doesn’t get dirty from what’s beneath it. Once the final snow melts, hidden debris may be revealed, so it’s another great time to call Wahlen and get your lot ready for summer.

Twice a year:

We recommend pressure washing twice a year for more than just aesthetic reasons. A proper pressure washing will help preserve the concrete surface by removing contaminants such as oil, beverage spills, and most import, salt. If left to sit on a concrete surface, salt can penetrate the concrete, resulting in pitted surfaces and rusted rebar. When the steel rebar begins to corrode, the structural integrity of the concrete becomes compromised , resulting in cracked, uneven surfaces, and weakened concrete. Pressure washing on a regular basis can delay this process for years, preserving the investment that you’ve made in the concrete surface.

Every other year:

In addition to keeping your lot or garage clean, it’s your responsibility to keep it safe for the drivers who will be parking in it. Ensuring you have clear and vibrant striping helps prevent confusion and keep drivers as well as pedestrians safe. Clear identification of handicapped parking stalls are also necessary requirements of the American with Disabilities Act. Not only does proper striping keep folks safe, it adds to the overall appearance of your building.

Every three years:

In addition to cleaning and striping, a well-maintained concrete lot or parking garage is sealed every 3-5 years. Concrete sealing is another measure of protection to help ensure your investment lasts as long as possible. Keeping up with your parking lot or garage maintenance schedule can be a lot of work, but that’s where Wahlen comes in. Wahlen Works offers sweeping, pressure washing, striping, and sealing services and we take on coordinating these efforts so you don’t have to. Contact us today to learn what we can do for you.
