Isoline 20 - Drainage membrane for concrete slabs - MatGeco

Isoline 20 is a PE-HD alveolar drainage sheet . It is used in particular for raft drainage , protection and ventilation of buried walls , drainage between two concrete slabs , etc.

Its high strength and low weight allow easy installation for both horizontal and vertical applications.

Use in horizontal drainage:

Place isoline 20 on the slab, knobs down, before pouring a second concrete slab on it. The rising water will thus be collected under the draining membrane avoiding the appearance of water on the ground. This principle of implementation allows, even in renovation, that underground car parks or underground cellars remain dry.

Use in vertical drainage:

Finally, used vertically with the structured face oriented towards a buried wall, the isoline ensures a separation between the ground and the wall. The mechanical protection and ventilation thus created will keep underground cellars or garages perfectly dry in the long term.

Applications:

• Under or over apron.
• Between 2 concrete slabs.
• Buried walls.

Advantages :

1. Lightweight, easy to apply, easy to cut.
2. Ventilation of buried walls.
3. Against rising damp.
4. Very resistant.
5. Mechanical protection.
