Blue Roof 108mm – Inverted – Hard Landscape – Pedestrian
The BLUE ROOF 108mm INVERTED – HARD LANDSCAPE – PEDESTRIAN system is one of the most popular stormwater attenuation build-ups. It offers a good balance between cost with a significant reduction in rainwater run-off volume to meet SuDS discharge limits.
The pedestrian access system with hard landscaping includes our standard 100mm void former layer installed between two Deckdrain drainage boards and our modular restrictor chamber positioned above rainwater outlets.
