BENTONITE GEOTEXTILE is a waterproofing material. It belongs to the family of geocomposites.

This geocomposite is made up of two geotextiles that encapsulate sodium bentonite, clay of volcanic origin that, when hydrated, has a high expansion capacity. The stitching between these two geotextiles and the bentonite material is hydrated creating a monolithic waterproof layer.

This nonwoven product confined with bentonite provides excellent results in both new construction and rehabilitation projects. It is highly resistant to weathering and humidity. On the other hand, it is an alternative to sealing with compacted clays.

The main function of this geotextile joined with clay is to waterproof horizontal and vertical underground extensions in buried roofs, slabs, concrete basement walls, cut and cover tunnels, diaphragm walls or formwork walls.
