TegraTite is a multi-layered membrane consisting of bentonite and 20 mil HDPE/high-density polyethylene

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, TegraSeal waterproofing is expected to provide long-lasting protection for your building.
