Cracksealing

Asphalt cracks come from many sources.  The main cause is lack of flexibility as asphalt ages which allows expansion cracks.  Insufficient rock base installed prior to the asphalt, as well as tree roots, heavy traffic and frost heaves from freezing temperatures,  can also be contributing factors to cracks in asphalt.  Once small cracks have opened, they will continue to enlarge and will need to be sealed with a flexible asphalt-rubber type sealant.

Cracks need to be sealed as quickly as possible.  For fine lines, cracksealer can be applied directly, once the surrounding area has been cleaned of dirt and debris.  For larger cracks, it is recommended that they be routered out to insure good adhesion and an adequate reservoir to allow for further expansion and contraction from the outside elements.

Pavement Protectors uses a high quality rubberized asphalt sealer manufactured by McAsphalt Industries Ltd, in Ontario Canada.  This product is commonly used by City, State and Federal departments on major highways and roads.

Once the cracks are ready for sealing, hot pour cracksealer (heated to 400 degrees F) is applied through a wand directly into the crack and surrounding lip area.  Once the sealer has cooled, it leaves a black, flexible top to the pre-existing crack, sealing edges from further erosion. Unfortunately, cracksealing does not erase the crack, it simply seals it and allows longer life from the asphalt.  It is recommended that once all cracks are sealed, the entire asphalt pad be sealcoated to further protect the surface.
