SOPREMA Colphene BSW-H SBS-Modified Bitumen Blindside Waterproofing Membrane, 39.4 in. x 32.8 ft Roll
Soprema Colphene BSW-H is a 140 mil (3.5 mm) SBS polymer-modified bitumen blindside waterproofing membrane reinforced with composite polyester/glass fiber. One roll measures 39.4 in. x 32.8 ft. The fine mineral aggregate top bonds to post-poured concrete slabs; pair with Colphene BSW PROTECT'R where added protection is required.
Key Features:
- 140 mil thickness: At 140 mil (3.5 mm), its robustness allows it to hold up to other trades on the job site.
- Composite reinforcement: Reinforced with a tough, dimensionally stable composite polyester/glass fiber.
- Concrete-bonding surface: Fine mineral aggregate topside bonds to the post-poured concrete slab.
- Burn-off film backing: Underside is surfaced with polyolefin burn-off film for installation.
- Blindside use: Formulated for below-grade blindside waterproofing applications.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Blindside membranes are applied to the shoring before the pour, so sequence delivery so rolls arrive when the excavation face is ready; the robust 140 mil build is chosen precisely because rebar crews work over it. Butt sheets tightly and seal joints per Soprema's detail drawings. Where jobsite traffic or rebar ties are heavy, spec Colphene BSW PROTECT'R over the field of the membrane.
Below-grade waterproofing installation involves confined excavation work; follow shoring, fall-protection and confined-space requirements on site.
Order Soprema Colphene BSW-H blindside waterproofing membrane by the roll for your below-grade pour.
