Levasil CB is excellent for use underground, especially in environmentally sensitive areas, thanks to its high ground consolidation and water sealing capabilities
Together with a gel-activator, colloidal silica creates an ideal sealing grout that accurately matches the targeted application and desired open time. By adjusting colloidal silica grades and concentrations, the perfect geological structure for consolidation can be achieved.
To achieve extremely watertight tunnel structures, cement grouting alone may not be sufficient. By combining traditional grouting with Levasil CB gel treatment, it is possible to create a durable seal of tunnels in various types of rock.
Permeation grouting with Levasil CB gel treatment is used to emplace a low permeability subsurface barrier in sand and silt formations. The low viscosity Levasil CB forms after gelling an impermeable barrier that is biologically and chemically inert, unaffected by filtration, and environmentally safe.
Liquefaction prevention is done by preventing the water from flowing freely in the saturated sand. The low viscosity Levasil CB solution penetrates the soil and replaces the water. Once the gel is formed it prevents the liquefaction from occurring.
When adding an accelerator (a salt solution) to colloidal silica, a gelling process starts. The formed gel network prohibits liquid transport within the gel volume and is a valuable tool in ground consolidation.
