SOPRANATURE DRAIN PLATE 40 is a 1.5 in tall, three-dimensional plastic drainage structure for green roofing systems. Unlike thin, flexible plastic drainage sheets, SOPRANATURE DRAIN PLATE 40 is a thick, semi-rigid board composed of high-density polyethylene designed to withstand heavy pedestrian traffic and last a lifetime.

Installation

Install drain plates over a layer of SOPRABARRIER Root Barrier. Overlap plates by two corrugations, staggering joints of adjacent rows by a half sheet to avoid having more than three layers at any point. When cutting plates, use a board to protect underlying materials from damage. Once installed, fill the area with water to prevent uplift in windy conditions or expansion in sunny conditions.
