Sodium silicate injection has two applications: structural ground injection and ground sealing (a water-resistant layer). The gel binds sand grains into a single mass. Structural ground injection uses a hard gel; ground sealing uses a soft gel.
Before water glass is injected by Grondinjectie Nederland, a soil investigation takes place. Based on the findings and calculations, sheet pile walls are placed and injection lances inserted into the sand layer. These injection lances form a certain pattern, covering the entire surface underground. After installation of the lances, a gel consisting of water glass, water and a hardener is injected. This gel fills all the pores in the sand layer, creating a water-inhibiting layer after curing.
At that time, the ground is completely sealed off from groundwater and you can realize your building pit and construction project without any problems.

This technique binds sand grains into a single mass using a gel made from sodium silicate, water and a hardener. It has two applications: structural ground injection and ground sealing (a water-resistant layer).
Structural ground injection uses a hard gel; ground sealing uses a soft gel.
First, the ground is surveyed. Sheet piles are then installed and injection lances placed in a pattern in the sand layer. The injected gel fills every pore and, once hardened, forms a water-resistant layer.
