Newton 320 Reservoir (HD320) HDPE studded membrane

Newton 320 Reservoir is a 20mm studded HDPE studded membrane for use above a primary waterproofing membrane as a part of a green/turf roof structure. The 20mm dimples act as a catchment zone for water so that the plants within the system have stores to draw upon when required. In the event of the 20mm dimples filling the membrane has overflow holes above the dimples on the flat surface of the drainage sheet.

The 20mm membrane also acts as a robust root barrier.

Newton 320 Reservoir comes in sheets 2.5m x 1.2m covering a surface area of 3m²
