Sodium silicate
High-quality liquid sodium silicate (commonly known as water glass) is widely used in civil engineering applications, particularly for backfilling and grouting in tunneling projects. Selected materials are supplied promptly to meet project requirements. Depending on the SiO₂ to Na₂O ratio and concentration, it can be applied in various grouting systems, including as a setting agent and for ground improvement applications.
