TamCrete 400CS

TamCrete 400CS is an environmentally friendly, highly stable, single component, ultra-low viscosity colloidal silica primarily used for injection into sands, silts, and fine joints and fissures in rock strata.

By adjusting the accelerator dosage, TamCrete 400CS can be used where very slow migration and penetration capabilities are required. The chemical properties and hydrophilic nature of TamCrete 400CS, ensures excellent adhesion to wet / saturated surfaces.
