Membrane Waterproofing Roll
Technical review pending. This reference record is awaiting verification against current manufacturer documentation. Confirm numerical values, product suitability and installation requirements before specification or use.
Overview
Membrane waterproofing rolls are sheets made from bitumen, modified bitumen, or synthetic materials used to create a continuous, flexible waterproof barrier on roofs, foundations, and wet areas. These rolls provide durable, long-lasting protection against water infiltration, UV rays, and temperature changes.
Main Uses
- Roof waterproofing
- Foundation protection
- Wet areas (bathrooms, kitchens, balconies)
- Concrete slabs and retaining walls
- Basement floors and walls
