The Crack Seal Project includes neighborhoods, as well as arterial streets all across the City. The work is divided between the City Streets Department and a private contractor. In addition to proper material preparation and application, a critical step in crack preparation is cleaning and drying the crack. First, the cracks are cleaned and dried using a hot compressed air heat lance. Then, the cracks are filled with hot poured rubberized joint and crack sealant.
Excess sealant is leveled off at the surface using a squeegee.
The air temperature during application should be 30 degrees farenheit and rising. The best time to seal cracks is during the cooler winter months when the cracks are the widest.
