While it’s common to use asphalt crack filling and asphalt crack sealing interchangeably, it’s important to understand the differences between the two methods of pavement crack repair in order to find the best solution for the crack in your asphalt surface. Homeowners in Sterling, AK, know they trust the professionals at Veir Corp for affordable and reliable driveway repair and pavement sealing services.

Here, the driveway repair professionals explain the differences between Asphalt Crack Filling and Asphalt Crack Sealing:

Asphalt Crack Filling

Asphalt damage is often caused when moisture seeps into or below the surface. When it freezes, the ice expands and leaves cracks and potholes in the surface. Non-moving cracks with moderate to no edge deterioration should be filled to reduce the infiltration of water and to reinforce the adjacent pavement. Non-moving cracks refer to horizontal and vertical movements in the asphalt, which are less than 0.1 inches.  The materials used for crack filling should be non-rubberized products such as crumb rubber and asphalt emulsion, because there is little need for flexibility.

Asphalt Crack Sealing:

Crack sealant is used on working cracks with horizontal or vertical movements greater than 0.1 inches. Unlike crack filling, asphalt crack sealants are made from rubber material, which offers the ability to seal the crack while staying flexible with the movement of the pavement. It’s beneficial for cracks that continue to grow in size and severity, as asphalt crack sealing restricts water penetration and prevents further deterioration.
