Complete Roof Garden Systems

KEMPERGRO® Uses and Benefits: * KEMPERGRO® is suitable for use in extensive roof gardens providing light-weight drainage and storage for rainwater in both newbuild and refurbishment projects. * The upper filter fleece supports the growing medium and stops substrate fines from blocking the reservoir but allows percolation of rainwater. * The factory bonding of the fleece to the reservoir core prevents sagging of the fleece under the weight of the substrate. This maintains reservoir capacity and stops blockages. * The reservoir core holds a predetermined amount of rainwater whilst enabling excess water to pass through percolation holes to the base layer. * The base felt layer offers physical protection to the waterproofing but also attenuates run-off to regulate flow to outlets and drains during flash floods and storms.
