Geotek CS – Colloidal silica for soil and rock injection


GeoTek 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. GeoTek CS is available in three grades with varying SiO2 content.

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