- A total of 1,860 star-shaped nodules and a volume of 5 l/m2 ensure effective protection of the water-resistant layer and adequate ventilation between the wall and the ground.
- Its high mechanical strength of 320 kN/m2, withstanding forces of up to 32 tonnes, means that the sheet has an excellent draining capacity over time since its nodules do not flatten, unlike other sheets on the market.
Advantages
- High mechanical strength.
- Excellent nodular structure.
- Resistant to chemical agents.
- Resistant to roots.
- Does not pollute the aquifer.
- Resistant to contamination by fungi and bacteria.
- Not degradable.
For drainage of buried structures such as walls, screeds, underpasses, tunnels and protection of the waterproofing membrane of the wall.
1. The medium must be clean, dry and free from loose debris.
2. It is recommended that the medium be waterproofed in advance using an Elastbit water-resistant paint PR01_0893199401
3. Attach the membrane to the wall using nails, with the nodules facing the waterproofed wall.
4. Overlap approx. 20 cm between one roll and the other, fitting the nodules together. It is advisable to use a self-adhesive strip, such as Tapeplus PR01_0894690 to increase the watertightness of the overlapping joints.
5. It is recommended to make the drainage channel at the bottom.
