Roof Drain 25mm 920mm x 50m 46 sq.m

Roofdrain is designed for use in extensive green roof systems. It provides both drainage and attenuation in a convenient, lightweight and cost-effective system. The drainage design of intensive green roofs requires only a simple soil layer; by contrast, the modern method of an extensive green roof requires a combination of efficient drainage and water attenuation to allow the ecology to flourish. Roofdrain allows the storage of water within the nodes of the HDPE core whilst facilitating the efficient drainage of any excess water away from the roof. This helps prevent the root growing media from drying out during dry periods and from becoming waterlogged during wet periods. When used within a roof construction, Roofdrain provides a versatile system for the collection of surplus seepage water at the base of the growing medium and for the prevention of water pressure on the structural waterproofing.
