TegraTite Plus Membrane 20 Mil 3.5' X 21.5' Roll

3.5' x 21.5', 20 Mil Thick, Virgin Resin HDPE, Green TegraTite Waterproofing Membrane

Bentonite clay is volcanic ash that expands when wet, absorbing several times its weight in water. The property of swelling makes bentonite unique as a sealant for below-grade waterproofing or as a liner for water retention. The TegraTite membrane combines the swelling properties of bentonite with the strength and protection of HDPE sheets to form a self-sealing waterproofing membrane. The tough HDPE membrane provides the primary waterproofing envelope while the expandable bentonite clay provides the self-sealing insurance, even under hydrostatic conditions, necessary for a complete waterproofing system. Because both the bentonite clay and the HDPE membrane are known to be very stable below grade, TegraTite waterproofing is expected to provide long-lasting protection for your building.
