Delta-NP Drain Protection and Drainage System

by Delta Membrane Systems Ltd

High drainage capacity through specially-configured dimples is offered by Delta Membrane Systems with its Delta-NP Drain – a compact two-ply composite sheet that keeps its shape perfectly, even under high pressure. Suitable for vertical and horizontal applications, this product promotes constant water drainage, and offers rot resistance and cost-effective installation. The dimple part of the sheet gives a high compressive strength of about 150kN/m2, and gives dependable vertical and horizontal drainage in civil engineering applications, retaining walls of all kinds, open tunnels and underground parking lots. Bonded to the dimpled sheet is a geotextile layer which filters out fine soil particles – ensuring a constant flow of water to the drainage.
