Plastics membranes

Needle-punched, non-woven geotextile polyester materials in two unit weights – 200 and 220 g/m². Suitable for uneven surfaces, e.g. traditional timber boards. They do not rot or cause adhesion and allow space for air flow between lead sheet and substrate.

Advantages:

• Reduce drag arising from thermal movement of lead sheet over substrate.

• Assist in the protection of lead against condensation corrosion, or chemical attack from stone, concrete or timber.

• Protect lead from damage due to any uneven nature of substrate and provide support against downward pressure.

Weed protection fabric for use beneath artificial grass rolls to help prevent weed growth.

Applications:
For use beneath CastleGrass artificial grass rolls.

Delta®-Drain is a high-density polyethylene (HDPE) double dimpled sheet with integral polypropylene geotextile for the protection of foundation wall waterproofing against mechanical damage, and for reliable drainage of stratified and slope water.

Safe solution for the protection of buildings and occupiers against all levels of hydrocarbon, methane, CO2 and Radon gas ingress. Conforms to BS 8485:2015 and requirements of CIRIA 748 VOC membranes. Resistant to range of aggressive hydrocarbons, durability and chemical resistance tested in accordance with EN 14414-A.
