Civil engineering/construction

Sodium silicate has been used in various industrial applications since around 1820, and in civil engineering it has been used to provide ground reinforcement, fire retardancy, and water sealing, thus contributing to the safety and security of people’s lives.

Ground reinforcement

Sodium silicate solidifies when it reacts with cement and other slurries.
It also has an extensive track record as a grouting agent.


Sodium silicate has long been used to make wood materials flame retardant. When injected with sodium silicate, wood materials become more resistant to burning.

Water sealing

For construction on soft ground, the ground is often injected with a grout like sodium silicate. Silica is widely used due to its high safety and minimal potential for soil contamination.
