PUBLIC WORKS DRAINTUBE T

In most cases, the tunnels or covered sliced built are closed on top by a concrete slab. Drainage on the surface of this slab prevents potential rainfall migrations which are detrimental to the durability of the structure.

Placed on the geomembrane, DRAINTUBE^® T makes it possible in just one operation to install filtration, rainwater drainage and mechanical protection of the geomembrane. It replaces the upper protective geotextile of the geomembrane, the layer of granular drainage materials and the filtration geotextile.

• Effective drainage under heavy stress
• Drainage of run-off water in the backfill material
• Protection of the waterproofing geomembrane
• Improved waterproofing performance by limiting hydraulic loads on the waterproofing layer
• Cost-effective and environmentally friendly solution which avoids the use of granular drainage materials
• Ease of installation with a single product to unroll

• Polypropylene geocomposite
• Roll width : 3.90 m
• Roll length : 50 m
• 3 diameters of perforated mini-drains : 16 mm, 20 mm and 25 mm
• 4 possible distances between mini-drains : 200 cm, 100 cm, 50 cm and 25 cm
