With care, paved areas can last for many years of use. In their service lives, asphalt parking lots and driveways experience the effects of traffic, environmental exposure, and moisture. Over time, this exposure and abuse can lead to cracks in the asphalt surface. Left unrepaired, those cracks can lead to further damage, making the parking lot unsafe in worst-case scenarios. Pin Point Line Striping & Marking is the service expert when it comes to paved areas. The company’s crack sealing methods can help protect these expensive paved areas, helping them to withstand the use and abuse they will experience for many years to come.
There are two major causes of cracks in paved areas like driveways and parking lots. The first is base erosion. The underlying “base” layer under the asphalt tends to settle over time, especially in high-traffic areas where vibration from passing vehicles cause the base layer to shift and compress. As the base settles, cracks can appear in the asphalt surface. When the cracks form, water can penetrate the surface, leading to further erosion and damage. Sealing cracks promptly can help divert moisture from the base layer, preserving its stability and reducing the chance of unsightly or dangerous damage.
The second cause of pavement cracks is environmental exposure, especially the exposure to damaging UV rays from the sun. Heat and sun cause small cracks to expand, allowing water intrusion. In areas where freezing temperatures are experienced, the freeze-thaw cycle can wreak havoc on paved areas that have cracked due to sun exposure. Prompt sealing of the cracks can prevent further damage.
Pin Point Line Striping & Marking is the industry crack sealing expert in the greater New England area. In addition to professional pavement marking and line striping, the company excels in repairing damaged asphalt with crack sealing processes.
There are two types of crack sealants: cold-applied and hot-applied. Each has specific applications, depending on the type and size of cracks as well as the amount of expansion and contraction the asphalted areas experience. Cold-applied sealants are designed to handle cracks up to one inch wide. Cold-applied crack sealants come in two forms; pourable sealants work for smaller cracks, while trowel grade crack fillers are best for larger cracks and those that will experience higher traffic.
Hot-applied crack sealants are designed for smaller cracks – up to about ¾ inch wide. These hot-applied crack fillers are pourable, and can be used to repair alligatored areas that have multiple small cracks throughout the asphalt surface.
In any crack-sealing repair, preparation is key to favorable results. Pin Point Line’s expert team of crack repair specialists carefully remove debris, dust, and moisture from the areas to be repaired. Some cracks need wire brushing to remove loose material. Once the cracked and damaged areas are prepared, the crack sealants are applied. The end result is a paved surface that looks great while gaining protection from further damage. Untreated cracks in asphalt can create unsightly parking areas and can cause further damage, both to the asphalt itself as well as to the vehicles that may use parking or driving areas. Sealing the cracks now can prevent extensive major repairs down the road. Pin Point Line can help avoid unnecessary expenses by sealing cracks before they can cause damage.
