The combined use of silica sol and a gel activator can form an ideal sealing grouting material, which precisely matches the target application and the required open time. By adjusting the grade and concentration of the silica sol, a perfect solidified geological structure can be achieved.
The permeable grouting treated with silica sol gel is used to create a low-permeability underground barrier in sandy and muddy formations. After the low-viscosity silica sol gels, an impermeable barrier layer is formed. This barrier layer is bio-inert and chemically inert, unaffected by filtration, and is environmentally friendly and safe.
