Water Drainage & Reservoir
All Nophadrain green roof systems, whether they be intensive or extensive systems, incorporate a build-up structure that replicates a natural soil profile and thereby creates a stable and natural growing environment for the planting scheme.Nophadrain provides a range of systems with guaranteed durability and functionality which is achieved by careful fine-tuning of the various build-up layers. The drainage and / or reservoir layer on any green roof is extremely important. A Nophadrain light weight layer relieves the waterproofing membrane of hydrostatic pressure. In addition, any excess water in the growing medium layer will be led away, preventing the potential ponding of water in the growing medium that may damage to vegetation.
