Cementitious Grouting
Cementitious grouting is a process of injecting a cement-based, flowable mixture into voids, cracks, or gaps in structures to fill them and provide structural support. Cementitious grout can be used beneath concrete slabs, in towpaths, under or between brickwork. We install different types of grout depending on the situation and environment.

Our Specialist Cementitious Grouting Services
Cementitious grouting can be used to fill voids, cracks or breakages in and around various structures. Cementitious grout will follow the line of leak paths to seal and fill to prevent the formation of further voids.
The grouting equipment is easy to transport and can be carried to site making it ideal for awkward access and remote sites.
A cement and bentonite mix grout is ideal for sealing leaks as the bentonite expands to fill the void with the cement creating a waterproof seal.
The main uses of cementitious grout are:
filling cracks
provide structural support
runs along leak paths to set & seal them
fills voids
