TamCrete 400CS – Colloidal silica for soil / rock fissure grouting

TamCrete 400 CS 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. TamCrete 400 CS is available in three grades with varying SiO2 content.

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