What Is a Geocomposite Drainage Sheet? How It Works, Types and Applications

What Is a Geocomposite Drainage Sheet? How It Works, Types and Applications

Water management is a fundamental challenge in virtually every civil engineering project. Whether it is preventing hydrostatic pressure from building up behind a retaining wall, removing excess water from the growing medium of a green roof, draining groundwater from a basement wall, or conveying leachate through a landfill drainage layer, the engineering solution invariably requires some form of drainage system. Traditionally, drainage was provided by ...

Typical roof garden sections

Typical roof garden sections

Below 2 typical roof garden sections. These are only to give an idea. Of course the designs change depending on the needs in the project. The upper with conventional design. For drainage 2 nonwoven geotextile (filter fabric) layer and gravel in between were used on top of the waterproofing layer. (mineral drainage layer) Heavy and cost more to take the gravel to the roof. Bigger ...

What is a PVD ?

What is a PVD ?

Prefabricated Vertical Drain - PVD Also called as wickdrain. Used for soil consolidation, settlement instead of sand drains. Typically 95 -100 mm wide by 3 - 5 mm thick Synthetic core wrapped with geotextile The core may be produced from different polymers (PVC, PP, PE or mixtures ...) The geotextile jacket type can differ depending on the producer. There are also many core types in ...

Tunnel drainage with geocomposites

Tunnel drainage with geocomposites

In TAG motorway project a geocomposite drainage product was used. The project was a cut and cover tunnel. To protect the waterproofing and also for drainage Enkadrain drainage sheets were used. All the tunnel covered carefully. The backfill around done carefully. composite geosynthetics are also used inside the bored tunnels.
