List of featured suppliers of DRAINAGE MEMBRANES Sub-Surface Drainage on Building Products Index
Drainage membranes refer to thin sheets or films used to create a waterproof barrier in construction projects. They are typically made of materials such as polymer or rubber and are placed over surfaces such as walls, roofs, or foundations to prevent the penetration of moisture or water. Sub-surface drainage, on the other hand, involves installing underground pipes or channels that direct water away from the building's foundation. These drainage systems are important for preventing water damage and maintaining structural integrity in construction projects.
