Parking Lot Maintenance
Protect Your Investment!

Sealcoating
The primary reason to sealcoat an asphalt pavement is to protect the pavement from the deteriorating effects of sun and water. When an asphalt pavement is exposed to sun, wind and water, the asphalt hardens, or oxidizes. This causes the pavement to become more brittle. As a result, the pavement will crack because it is unable to bend and flex when exposed to traffic and temperature changes. A sealcoat combats this situation by providing a waterproof membrane which not only slows down the oxidation process but also helps the pavement to shed water, preventing it from entering the base material.

Property owners who regularly sealcoat their asphalt, SAVE MONEY. You can protect your asphalt and therefore extend the life of the asphalt. Some say almost indefinitely. Seal coating greatly improves the appearance of your parking lot.

Asphalt Patching
Asphalt patching consists of saw cutting the existing asphalt around the failed area, ensuring that all cuts are straight and corners squared. The failed area is excavated to the specified depth, which is at least as deep as or deeper than the existing asphalt, and the failed material is hauled off-site for recycling. Alternatively, for larger failed areas, a milling machine may be brought in for a more efficient method of removing large quantities of asphalt.

The existing aggregate base is inspected for proper load-bearing strength and repaired as required or as specified.

Repairs
Different types of cracks and their causes:

Cracks due from shrinkage are temperature related and result from the inability of the pavement to handle the stresses caused by temperature variations.

Reflective cracks occur in pavement overlays that were placed over unprepared pavements in poor conditions. As the joints open, they induce tension on the bottom of the asphalt overlay. Left unsealed, the crack will allow moisture into the aggregate and result in premature failure.

Alligator or fatigue cracks are a series of interconnecting cracks in the asphalt surface forming a pattern that resembles an alligator's hide or chicken wire. The cracks indicate fatigue failure of the surface layer generally caused by repeated traffic loadings.

Edge cracks are caused by insufficient shoulder support, poor drainage, or frost action. These cracks usually start as hairline or vary narrow, then widen and erode with age.

Potholes are what most people think of when they think of pavement failures. These are usually non-functional pavement areas where the pavement has completely failed, exposing the base aggregate beneath it. Potholes can pose liability issues such as causing vehicular suspension damage, or tripping hazards if they reside within pedestrian walkways. Potholes are often the result of several years of failing pavement in areas of fatigue where pre-emptive repair was not done until the area has completely failed.

Potholes should be saw cut around the entire failing area, excavated, and base repaired using fresh stone. Then proper placement of the asphalt design specification is completed. The asphalt design specification varies from job to job.

Line Striping ADA Markings
Parking Lot and Street stencils are designed for driver and pedestrian safety and awareness. No Parking, Disabled Parking, and Directional Arrows all assist drivers in navigating their vehicle around your premises.

Some popular standard and custom stencils include:
  • No Parking
  • Staff
  • Office
  • Loading Zone
  • Visitor
  • Welcome
  • Fire Lane
  • Directional Arrows & Turning Arrows
  • Expectant Mom Logo
  • Baby Carriage Logo
  • Pedestrian
  • Alphabets (A-Z)
  • Numbers (0-9)
  • Company Name
Concrete
Contrary to popular belief, concrete and cement are not the same thing; cement is actually just a component of concrete. Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.

When most contractors think about concrete mix design—if they think about it at all—the first thing that comes to mind is "bags" or "sacks." In the old days, when most concrete was mixed on site, cement was purchased in bags. A bag is 94 pounds of cement - about 1 cubic foot. But if you order a 6-sack mix, all that tells you is how much Portland cement is in the mix. That mix could be completely wrong for your application and could even be inferior concrete. What slump do you need? What strength? Do you need entrained air? What happens if the day is particularly cold or hot? What size of aggregate is best? Should you ask for fly ash in the mix?

The right concrete mix ratio can solve problems or it can create them. What you really want in a concrete mix is one that is easy to place, strong enough to meet the needs of the application, durable for the life of the floor or wall, and that will look good when you're done with your decorative efforts. We don't rely on bags! Rather than only specifying how much cement is in the mix we should be specify things like permeability, shrinkage, workability, pump-ability, stamp-ability, and stain-ability.
