Nophadrain ND 4+1h | HIPS Composite Dimpled Drainage Membrane
DrainageDescription
The only one with a recycled HIPS core — a perforated high-impact polystyrene core, where the holes allow water and air to pass through in both directions. High-performance composite drainage sheet with an integrated geotextile filter.
Part of the comprehensive EshaOxygen system, the ND 4+1h is selected for extensive and intensive planting schemes where increased drainage height is required, high water storage capacity (4.3 l/m²) and a compressive strength of 600 kPa (≈6 t/m²).
Overview
Key Features
- 17 mm thick HIPS core — high water storage capacity of 4.3 l/m² for water-saving irrigation
- PP geotextiles bonded on both sides (not heat-sealed) — optimum filtration, no clogging in the cones
- No memory effect — remains flat after unrolling, ready for installation
- Flange for additional protection of the waterproofing membrane
- High compressive strength & creep resistance — consistent long-term performance
- Lightweight (1,010 g/m²) — one person can carry the rolls
