Drain sheet, drainage sheet, HDPE Drain sheet

Drain sheet HW-PSD10 is a dimpled plastic sheet that provides effective drainage and waterproof membrane protection on foundation walls and other underground structures. The integrated non-woven geotextile covering the dimples prevents soil particles blocking the drainage sheet, creates an air gap for reliable ventilation and allows inflow and transport of water from surrounding soil. Drain sheet HW-PSD10Geo with its dimple structure effectively captures and transports high water volumes and resists high loads from earth and formwork. Drain shee HW-PSD10Geo is installed with the geotextile facing the backfill. Applications Typical areas of application include: Retaining and basement walls Tunnels and landfills Paved areas Roof gardens and landscaped decks Advantages Provides an efficient drainage system for underground structures Acts as a protection layer over waterproofing membranes Creates a vapour and thermal insulation barrier adjacent to waterproofing membranes Compressive strength permits usage in moderate load-bearing situations of up to 250 kN/m2 (25 t/m2)* Wide and easy to handle rolls result in rapidand low cost installation Specifications Material: High density polyethylene Weight: Approx. 775 G/M2 Sheet thickness: Approx. 0.6 mm Dimple height: 10 mm Void volume between dimples: Approx. 5.3 l/m2 Drainage capacity: Approx. 4.6 l/s. M approx. 276 l/min. M approx. 16, 560 l/h. M Geotextile weight: 136 G/M2 Geotextile water transmission: Approx. 100 l/s. M2 Compressive strength: Approx. 250 kN/m2 (25 t/m2) Service temperature: -30º C to 80º C Biological/chemical resistance: Resistant to ground chemicals, rot, moulds, algae, bacteria and root penetration. Does not affect potable water. Drain shee 8 Geo may be fastened to substrates using proprietary HuwaDrain® Fixing accessories.
