Hychem Soil CS30 is a single-component, ultra-low viscosity colloidal silica system engineered for permeation grouting applications in fine-grained soils such as sands and silts, as well as for sealing microfractures and discontinuities in rock strata. The material exhibits high chemical stability and is environmentally benign, making it suitable for use in sensitive geotechnical and underground environments. The formulation allows precise control over gel time through modulation of the accelerator concentration, enabling deep penetration and controlled setting in low-permeability substrates. Its hydrophilic characteristics facilitate strong adhesion to moist or fully saturated surfaces, enhancing long-term sealing performance in wet conditions.
