How To Fill Cracks With Injection Grout

Filling cracks with injection grout is a useful procedure that helps provide waterproofing and corrosion protection for structural purposes.

A variety of grouts are available on the market with different characteristics, properties and uses. Generally, grouts used for crack repair should have low viscosity, high bond strength, low shrinkage and high stability at the repair temperature.

The main types of grout used for injection are cementitious grouts, epoxy grouts, polyurethane grouts and acrylate grouts. A particular grout may be ideal for one purpose but inappropriate for another. It is therefore important to understand the characteristics of the different types of injection grout before selecting it.
