Product Details

PRODUCT DESCRIPTION

Enviro BSM is a premium pre-applied composite HDPE sheet membrane system engineered for waterproofing the blindside of concrete slabs and walls. Its three-layer design — comprising a robust HDPE base layer, pressure-sensitive adhesive core, and weather-resistant protective surface — forms a continuous, fully bonded barrier to concrete, eliminating lateral water migration.

Once installed, the membrane becomes integrally bonded to the concrete structure, ensuring maximum protection against hydrostatic pressure, chemical attack, and methane gas infiltration. Enviro BSM’s durable and trafficable surface allows for steel placement and concrete pouring immediately after application.

Perfect for commercial, industrial, and residential use, Enviro BSM offers unmatched reliability for long-term waterproofing and gas barrier performance in the most demanding below-grade environments.

Product Limitations
