Protecto Drain G8 is ideal for use in conjunction with subterranean applications and foundation walls where a greater degree of drainage and protection is required on the vertical plane.
Geotextile Properties
Protecto-drain G8 is made from the same HDPE (high density polyethylene) material, but has a geotextile fabric bonded to one side. It is designed to protect vertical surfaces from damage with the laminated non-woven geotextile layer separating the soil from the membrane, giving greater protection to the subterranean waterproofed surface. It is also lightweight and simple to install.
It creates an air gap between the structure and the earthworks, ensuring complete protection to the waterproofing membrane on the structural wall after backfill.
Special Design
Protecto-drain G8 is installed with the geotextile fabric facing towards the soil backfill. Water will pass through the geotextile but the HDPE cupped membrane prevents further ingress. The water will fall down the face of the HDPE membrane with the force of gravity. The specially designed profile and the high compression strength of the cupped HDPE means that a constant air gap is maintained, preventing clogging of the drainage channel.
Easy to Handle
The HDPE is very lightweight and easy to handle. This makes it ideal for fixing to the vertical plane.
The area immediately behind the Protecto-drain G8 should be filled with free-draining material such as shingle to improve drainage. Since effective drainage occurs but the soil remains in place, the earth will not become eroded or saturated near the drainage areas. Therefore, common problems such as subsidence, waterlogging and rising damp are avoided.
