CM8 Geotextile Membrane is a twin layered cavity drain membrane and non-woven geotextile fabric, designed to manage water to land drains, relieving pressure from the structure.

8 mm studded HDPE membrane and a nonwoven geotextile manufactured from UV stabilised, high tenacity, virgin polypropylene fibres that have been mechanically entangled to provide high strength, high extensibility, high loft and excellent abrasion characteristics.

The geotextiles are also thermally treated to reduce thickness while maintaining excellent mechanical properties.

CM8 is also ideal for use on a green roof. Green roofs can range from roof gardens with raised beds and pots, to rolled-out green carpets, to shed roofs containing planting cells that are filled with soil or compost and planted up with low growing perennials and grasses.

CM20 Geotextile is an ideal Radon Barrier.

• Excellent flow rate.

• UV Stabilised.

• Suitable for use with all construction types.

• Drains off the water before reaching the waterproof coating.

• Combined drainage and protection board.

• Easy handling and rapid installation.

• Rugged, durable construction with thermal insulation benefits.
