GEODRAIN PLUS | Drainage pipe with geotextile
DrainageDescription
The pipe with an integrated geotextile sleeve — no separate wrapping required on site, no risk of it coming loose during backfilling. 4-layer subsoil drainage pipe, an evolution of GEODRAIN, where the filter prevents fine particles from blocking the holes.
1st layer — smooth inner surface for unimpeded water flow
2nd layer — annular outer surface providing flexibility and high mechanical strength
3rd layer — four longitudinal blue lines for colour-coding the water (NF P 98-332)
4th layer — pre-installed geotextile, 150 g/m², non-woven and needle-punched
Ring stiffness SN4 (EN ISO 9969), type R2 according to DIN 4262-1, 360° TP symmetrical perforation with an inflow area >50 cm²/m. Diameters Φ63 to Φ200 mm, supplied in rolls of 50 m (Φ63–125) and 25 m (Φ160–200).
Overview
Key Features
The geotextile (4th layer)
- 150 g/m², non-woven, needle-punched
- UV-resistant (UV stability)
- CE marking + Declaration of Performance in accordance with the Construction Products Regulation
- Installed around the perimeter at the factory using a modern bonding method
- Pore sizes dimensioned for 90 per cent of soils in Greece
- Retains fine particles and prevents internal blockages
The pipe
- Specially stabilised HDPE, free from halogens and heavy metals
- Double-walled construction — smooth internally, corrugated externally
- Ring stiffness SN4 (EN ISO 9969), type R2 (DIN 4262-1)
- 360° TP perimeter perforation, surface area >50 cm²/m
- Rodent-repellent coating on the inner wall (EP2698792)
Durability & marking
- UV resistance: 5 years
- Chemical and corrosion resistance (DIN ISO 10358)
- Four longitudinal blue lines in accordance with NF P 98-332
- Marked by engraving — not printing — so that it remains visible beneath the geotextile
- White safety rings, two protective caps per coil
