BentIzol® 2-D drainage mat — geocomposite for trench and blanket drainage
Drainage geocomposite of polyethylene geonet with geotextile on one side for drainage of foundations, tunnels and roads.

In this version, a layer of bentonite powder is factory-applied along the longitudinal edges of the mat over the overlap width, so the overlaps are not sprinkled with granules, and on vertical and inclined surfaces no bentonite paste is needed. This speeds up installation and increases the reliability of the seams. Self-sealing edges are available for BentIzol SAB4, SAB5, SB4, SB5, as well as MASTERBENT and MASTERBENT P; the mats are used at oil and gas and mining facilities, landfills, hydraulic structures, and in industrial, civil and transport construction.
