WEBAC® SILfill

 

WEBAC SILfill is a low-viscosity silicate injection foam resin. Even without contact with water, it forms a fine-celled foam with a high expansion ratio and cures quickly into a material that can be cut and planed. The resin is used for shield injection in the immediate vicinity of TBMs, as well as for subsoil stabilization and rock reinforcement.
