Self-Adhesive Membranes

LONGSEAL Self Adhesive Waterproof Membranes

Longseal membranes are cold applied, CE-certified membranes suitable for a range of waterproofing applications. They utilize a rugged, cross-oriented HDPE (high density polyethylene) film to a layer of rubber-modified bitumen adhesive. The HDPE-backing provides superior product performance in terms of tear strength, tensile strength, puncture resistance and dimensional stability. Additionally, Longseal membranes conform well to a variety of site applications

In addition to the Longseal (LS) 100, Chase offers the Longseal GR (Gas Resistant) WBX (winter-boxing) which provides added protection from methane and radon gases.

Product Benefits Include :

Immediate bond to the substrate	Factory control thickness
Cold applied – no heat required	Cross-laminated HDPE carrier
Zip strip for overlap integrity	GR provides methane/ radon barrier
