Hot Rubberized Crackfill is the application of a heated rubber compound to asphalt cracks. This fills the crack and seals it from further water penetration. The cracks are cleared of all vegetation and debris beforehand.
Crackfill is used to repair large, singular cracks. If left untreated, these cracks will lead to further damage, as water seeps in and enters the sub-base of the asphalt, eventually leading to “alligator” cracking, and then potholes.
Hot Rubber is used because it effectively seals the crack, while also being elastic, expanding and contracting with the weather and climate. Crack seal is meant to be a short-term solution, acting as a “band-aid” for the asphalt and preventing any further damage, until an Overlay or Remove & Replace can be performed.
