Microfine Cements are blast furnace slag based cements composed of ultrafine particles and are designed for injection into loose soils, rock and concrete. They feature a maximum grain size ranging from a D*5 of 6µm to a D*5 of *6µm. Depending on the application and the permeability of the strata, different grain size can be used. It is suited for stabilizing or sealing all earthen foundations; especially for permanent structures such as tunnels, dams, deep foundations and oil storage tanks. Because they cure into a hardened concrete, Microfine Cements cause no pollution to underground soils or water supplies.

Benefits:≥

-Excellent penetration in tight joints, fissures and pore spaces

-Improved water tightness following proper application

-Better working environment

-Improved grouting efficiency and less waste
