Asphalt driveway cracks can result from a number of factors including tree roots, poor drainage, freeze-thaw cycles, oxidation from the sun or excessive weight. Asphalt cracks allow moisture to penetrate the pavement. In the winter this moisture can freeze causing a multitude of more serious problems. In the warmer months weeds or grass can take root in the cracks causing extensive damage.
Your best defense against pavement deterioration is crack sealing. By sealing cracks you can extend the life of your pavement considerably and prevent more costly repairs.
Two Types Of Crack Filler
Cold Pour Crack SealerA pourable asphalt emulsion based premium liquid. Available in one gallon jugs, this material enables a quick, easy application and penetration in cracks up to 1/2" in width. This is the material we use to seal cracks in our standard sealing service.
Hot Pour Crack SealerA fast curing, premium quality, hot applied single component crack and joint sealant that will seal larger cracks up to 1 1/2" in width. First we remove dirt and vegetation from the cracks using any required combination of routers, hand tools, power blowers, and heat lances. The crack sealer is heated to approximately 350 degrees in a melting unit, transferred to an applicator, and applied directly to the cracks. The excess material is banded over the crack to form a tight seal. While no crack filler is permanent, the hot pour is a much longer lasting, more durable product. The only drawback from a residential standpoint is that it will be more visible than the cold pour.
Cracks We Fill
Cracks We Do Not Fill
The only way to properly repair these conditions is by replacing the affected asphalt.
Cracking EdgesCracking, breaking, and crumbling along the driveway sides can not be effectively treated with sealer or crack filler.
Spider Web or Alligator Cracks
In you have what is referred to as "alligator" or "spider web" cracking (terms used because the cracks resemble alligator skin or a spider web,) sealing won't help. This is characterized by numerous cracks close together.
Gaps between the asphalt driveway, concrete garage floor, sidewalks, and other adjacent surfaces will not be filled or treated.
