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
