Younson HDPE Non-Asphalt-Based Self-Adhesive Polymer Waterproof Roll is made with an HDPE polymer sheet base, combined with a non-asphalt polymer self-adhesive layer and a special particle anti-stick layer or release film anti-stick layer. It is designed to bond effectively with cast-in-place concrete. Special active substances in the adhesive allow cross-linking with fresh concrete, achieving full microscopic adhesion (pre-laid self-adhesion), preventing water seepage, and forming a “rigid-flexible complementary” waterproof system.
Product Specification Type
- Top surface: special particle anti-stick layer or release film anti-stick layer (the release film type is used for auxiliary installation)
Scope of Application
- Suitable for underground constructions, vaults, tunnels, subways, municipal construction, and other waterproofing and anti-seepage projects.
