Does a TegraSeal waterproofing system also provide a vapor barrier per ASTM E1745 and ACI 302?

Yes, TegraSeal membranes exceed the ASTM E1745 requirement for water vapor transmission rate and for puncture/tensile strength. The combination of HDPE and bentonite in TegraTite and TripleSeal provides protection from both hydrostatic head and water vapor transmission. We also have design specifications for methane and radon mitigation.
