Residential Crack Filling
Crack filling is your first line of defense against pavement deterioration. Cracks allow water to more easily penetrate into the pavement and weaken the sub base. The freeze thaw process will widen these cracks leading to pot holes. Please read all of the information below as to completely understand the residential crack filling process.
Cracks from ¼ up to 1" in width can be cleaned then filled with hot rubberized crack filling material. (See exceptions below) We begin by cleaning the cracks of loose debris, vegetation and moisture with a hot air lance. A hot air lance is a combination of compressed air and a propane torch. This process will ensure proper adhesion of the crack filling material. The crack filling material is a rubberized material heated to 350 degrees when applied. This liquid material fills and seals the cracks, hardening in just minutes allowing your driveway to be open for traffic in as little as 15-20 minutes.
Hot rubberized crack filling material is the material of choice for commercial applications. You may have noticed the 3" black swirly lines in a parking lot or on the roadway. This is the same type of material we apply to the cracks in your driveway. It fills and seals cracks better than any cold applied crack filler. There is one downside to using this material on a residential driveway. Even after we apply the driveway sealer the lines will be visible. Most homeowners understand that this is necessary to protect the driveway and hardly bothered by it.

Cracks which closely intersect one another resembling a spider web or alligators' back are referred to as Alligator cracks. This type of cracking indicates a more severe problem below the pavement. Typically a weak or wet base causes these types of cracks to begin to form on the bottom of the asphalt. So what you see on the surface is only part of the area that is cracking. We DO NOT crack fill alligatored areas. The pavement here is weak and could pull up. The only proper cure is to cut out the pavement beyond the visibly cracked area, remove the pavement, inspect and repair the base material and patch the pavement.
When a section of your driveway is beyond crack filling or may have a sunken or raised area, a more severe repair may be required. When necessary, the area may be cut out, the damage pavement removed, the base inspected and repaired if needed and then new pavement installed. Depending on the size of the repair either hot or cold asphalt may be installed. For small areas, typically less than ten square feet, cold asphalt can be installed. Exceptions are along the outer edges of the driveway or high traffic areas. These and all larger areas should be made with hot asphalt.
