What’s the difference between crack sealing and crack filling?
Crack sealing is the placement of specialized treatment materials “Hot rubber” into working cracks to prevent the intrusion of water or incompressible material, such as sand, stone, and dirt. Crack filling is the placement of ordinary treatment materials into non-working cracks to substantially reduce infiltration of water and to reinforce the adjacent pavement.
When is it best to seal cracks?
The sooner, the better. Any crack in the pavement will allow moisture to penetrate to the subsurface and shorten the life of the pavement. Substrate and air temperatures must be above 40° F and the surface should be properly prepared before sealing. Dynamite Paving recommends crack sealing every year if possible.
