Crack filling services are primarily used to fill in cracks on concrete surfaces. These surface cracks can be caused by a variety of reasons, including wear and tear, environmental changes, and improper installation. Crack filling can be done by hand or with machinery depending on the size and depth of the crack needing to be filled.

Crack filling is a process of filling cracks and voids in concrete structures to prevent the ingress of water and other harmful agents.

The process of crack-filling is done by injecting a sealant material into the cracks and voids. This sealant material is usually an epoxy resin, polyurethane or polystyrene.
