Geomembrane Clay Lining

Use of geomembranes to seal clay maintains clay moisture content, thus preventing its swelling.

Sealing of the subbase is carried out when the clay has been worked to the desired moisture content, whereupon HDPE membranes are spread on the horizontal substrate as well as vertically in a 1.5 : 2.5m deep trench, intended to prevent penetration of horizontally flowing ground water. Sealing the clay prevents damage to its surface and prolongs road lifetime.
