Hot Rubber Crack Fill
Routed Preparation & Application
Singular cracks (not alligator-like areas) that are less than 1/2" wide are routed with a mechanical router. Then cracks are thoroughly cleaned of all vegetation and foreign matter with an industrial air compressor and/or high power blower. The cracks are properly sealed using a state-of-the-art oil-jacketed crack sealing machine with a rubberized hot pour material meeting federal spec 3405.
In the oil-jacked system the material is hydraulically agitated, then pressure fed through an oil-jacketed pump and injected under pressure directly into the crack at optimum temperature to prevent decomposition of the material and to maximize adhesion.
Over-banded Application
Singular cracks (not alligator-like areas) that are more than a 1/2" wide are thoroughly cleaned of all vegetation and foreign matter with an industrial air compressor and/or high power blower. All deep cracks are then prefilled with silica sand within 1/4" from the surface to help prevent hot rubber from sinking. Rubber is then applied using a banded method 1/2" wider than the crack on either side. This prevents water from sitting directly on or near the crack.
