BentIzol® SB L 5 bentonite mat — laminated liner on natural bentonite
Laminated mat on natural sodium bentonite for anti-seepage liners in media with pH 1–13; water pressure up to 7 atm.

The textured version of BentIzol® GM is made on the basis of HDPE and LLDPE in the HDPE-T, HDPE-ST, LLDPE-T and LLDPE-ST variants with texture on one or both sides and corresponds to geomembranes of types 4/1 and 4/2. The membrane is resistant to acids, alkalis, petroleum products and oils at pH 0.5–14, to ultraviolet radiation and to repeated freezing and thawing, works from −60 to +60 °C and lasts at least 50 years. It is used for liners of MSW landfills, tailings storage facilities, oil and gas facilities, canals and reservoirs.
