Cements and Chemical Grouts
Cement grouts are predominantly used in new construction to strengthen soils or to stabilize rock and control groundwater flow for dams, tunnels, and subways. For rehabilitation projects, they can be used to lift structures back into alignment, such as correcting a sagging pipeline. The majority of our grouting projects use cement grouts for new construction projects, ranging from dams and tunnels to subway construction.
However, we also employ acrylamides and acrylates as special-use grouts, as they lack suspended solids and have extremely low viscosity – similar to water. These acrylamides control groundwater infiltration when rehabilitating sanitary sewer pipelines. As two-component grouts, they have a base resin that is mixed with a catalyst to create a gel or gel/soil matrix within a controllable time.
