💡 What makes a polyethylene waterproof underlayment reliable for bathroom and roof applications?
- The dense polymer matrix creates a continuous hydrophobic barrier that stops bulk water migration while still letting trapped vapor escape.
- This handy synthetic sheet handles constant exposure to splash zones and outdoor humidity without breaking down or losing its grip.
- Engineered tensile strength matches the weight of ceramic tile and heavy roofing granules, preventing sagging or tearing during fastening.
- Direct bed installation over mixed mortar gives contractors a predictable bond line every time, cutting prep work and call backs.
