Crack Sealing
Why Chamberlain crack sealing? We have highly trained crews and two State of the Art application units that ensure accurate temperature, accurate placement and longer lasting repairs than any other contractor.
Large cracks of 3/8" and greater have much more movement with changing temperature conditions and therefore need to be filled with a material that also has a very high elasticity. Our hot applied crack sealant will fill larger cracks up to 1-1/2" in width. First we remove dirt and vegetation using hand tools and our heat lance system. The heat lance dries the crack by forcing hot air into the crack at 2,000 degrees Fahrenheit at 1,000 pounds per square inch. This system also assures proper bonding of the hot pour crack filler by drawing liquid asphalt from the pavement to the edges of the crack and acting as an additional bonding agent. Crack filler is then heated to a pourable consistency approximately 350 degrees Fahrenheit in a melting unit with thermostatic control. The crack sealant is applied directly to the crack using a hand wand and the excess material is banded over the crack with a squeegee to form a tight seal over the surface. This material is extremely flexible and will move with the expansion and contraction of the pavement, and keep water out.
Sealing cracks is the most economical way to prevent future asphalt deterioration and asphalt expenses. Small cracks of 1/4" or less can be effectively sealed using a pourable sealant. Contact your Chamberlain representative to see what service will be most beneficial for your pavement.
