DANODREN® H25 PLUS is a brown nodular membrane with a 7.5mm depth, made of high density polyethylene (HDPE) with a pre-bonded nonwoven polypropylene geotextile. Its main use is for protection and vertical drainage.


  • Drainage in accessible inverted roofs with continuous paving, placed between the thermal insulation and the paving.
  • Drainage and protection of the waterproofing of buried walls in buildings and civil works, such as cut-and-cover tunnels and subways.
  • Drainage and protection of above-ground screeds.

Advantages & Benefits

  • The geotextile fused to the nodules absorbs and filters water from the ground, preventing the system from clogging.
  • Easy and quick to install.
  • Rot-proof.
  • Chemically unchanged when in contact with chemical agents present in the soil (sulphates, chlorides, etc).
  • Provides permanent drainage.
  • Protects the wall from damp and allows water to drain, limiting its hydrostatic pressure.
  • Protects the waterproofing sheet from possible piercing caused by fill earth.
  • Resistant to breakage, impact and does not deform.

Instruction for Use

Buried walls

1. Surface and singular points must be uniform, clean, dry and free of foreign objects.

2. The support of DANODREN H PLUS can be a waterproofing membrane.

3. DANODREN H PLUS is placed with the geotextile against the ground.

4. The geotextile layer has a width of 5 cm less than the drainage sheet to facilitate the overlap of roll with roll. To perform the overlap, the geotextile is detached 7 cm, exposing 12 cm of drainage sheet, where the overlap will be made with the following sheet.

5. DANODREN H PLUS is fixed every 50 cm along the length and width of the overlap with DANODREN fixings. You can also use HILTI fixings, model X-SW.

6. DANODREN H PLUS is fixed mechanically in their upper part with the DANODREN metallic profile. This protects the drainage layer of land dumping, filling and compacting of the ditch and the water entrance. This fixation must be done 10 cm over the waterproofing membrane.

7. The corners should be made by folding the membrane.

8. Lay the drain pipe.

9. Rolls can be extended from top to bottom or vice versa and from left to right or vice versa, depending of the characteristics of work.

1. Where there is hydrostatic pressure or the floor is under the phreatic level, DANODREN H PLUS is extended with the geotextil against the ground. The overlaps are done as same as underground walls
Walkable inverted roofs with continuous pavement

1. In walkable inverted roofs with a continuous pavement, DANODREN H PLUS must be placed on the thermal insulation with the geotextile upwards. The overlaps are done as same as underground walls.
