High-density polyethylene (HDPE) membrane with a conical truncated structure. A smooth polypropylene filter cloth is attached to one side. Its drainage system is characterized by high efficiency and considerable compressive strength. Creates drained depressions on floors and walls of underground structures. Specially designed cones collect water and discharge it from the surface to an appropriate drainage system.

Features

• excellent chemical resistance to bases, acids, solvents and all common underground salts
• high compressive strength
• high drainage capacity
• the product reduces the hydrostatic pressure acting on underground structures and extends the life of waterproofing coatings
• root resistant
• easy to install system
• does not rot
• suitable for contact with drinking water
• compatible with cement-based materials and other commonly available building materials
• creates thermal insulation to some extent

Application

• drainage system, courtyard in, green roof in and concrete slabs fixed above the ground, planted with greenery
• protection of waterproofing coatings covering the foundations
• drainage and protection of passages and tunnels
• protection and drainage of the foundation and retaining wall
• ventilation of partition walls and retaining walls
• a protective layer of concrete slabs, preventing the rising of moisture as a result of their direct contact with the ground
