Noten Drain (PED10) / Membranabdichtung

sheet drainage, Sheet Drain(PED10)is a dimpled plastic sheet with applications for: §internal drainage of basement walls §creating a capillary break under concrete ground slabs §waterproofing membrane protection of underground structures Sheet drain acts as a barrier giving protection to the waterproofing membrane from the backfill. The dimples create a vapour and thermal insulation barrier in both internal walls and walls adjacent to waterproofing membranes. Sheet drain offers protection against rising damp in ground slabs and replaces traditional lean concrete sub-base slabs without compromising the load-bearing capacity of the sub-base. Sheet drain creates a cavity control layer when placed between the reinforced concrete base and concrete floor surfaces in chemical storage areas allowing continuous monitoring to determine leakage of chemical containers. APPLICATIONS Drain Board drainage sheets provide efficient drainage on: §Ground slabs §Basement walls §Tunnels § Chemical storage areas Benefits Dimpled drainage sheets offer many advantages including: §Wide, lightweight rolls that allow rapid and low cost installation § Creation of efficient drainage and vapour barriers between diaphragm and internal walls § Resistance to puncturing when installed as a vapour and drainage barrier under concrete slabs §Replacement of lean concrete sub-base slabs without compromising load-bearing capacity §Creation of a cavity control layer in chemical storage areas §Acting as a protection layer over waterproofing membranes Features Drainage Sheet soffer several unique features including: §High compressive strength in excess of 100t/m² §High surface void area and internal void volume resulting in efficient water capture and discharge rates §Modules that may be interlocked in one plane or at right angles to one another § Resistance to biological attack and to a wide range of soil-borne chemicals Large pre-assembled panels that allow rapid installation and minimise on-site disruption Specifications Material High density polyethylene Weight approx. 580 g/m Sheet thickness approx. 0.9 mm Dimple height 10mm Void volume between studs approx. 5.3 l/m² Discharge Capacity approx. 4.6 l/s.m approx. 276 l/min.m approx. 16,560 l/h.m Compressive strength approx. 250 kN/m² (25 t/m²) Service temperature -30°C to 80°C Biological/ chemical resistance Resistant to ground chemicals, rot, moulds, algae, bacteria and root penetration. Does not affect potable water.
