Chemical Grout

Faster Gel Time for Chemical Grout

When you need a fast, reliable solution for grouting underground tunnels, Sodium Bisulfate is the answer.

Sodium Bisulfate for Chemical Grout

Sodium bisulfate acidifies grout formulations to form a temporary seal when constructing underground tunnels. Combined with aluminum sulfate, magnesium sulfate or other fillers, sodium bisulfate forms a dry compound that is then put in a water solution and combined with liquid sodium silicate for spraying on tunnel walls. The more sodium bisulfate (SBS) added, the faster the gel time of the grout formulation.
