To compare with the geocomposite drainage products let's remember the traditional drainage layers :) Traditional drainage layers are made of graded granular material the granular filter prevents penetration of fines into the drain (Filtration) the granular core transports the water in the plain of the filter (Drainage)
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 ...
From bottom to top layers:
Now it is spring and you may want to prepare a green roof. You know roof garden does not mean a garden on the roof only. It may be top of an underground garage or top of a underground structure. An important thing is not to forget the drainage core of the drainage sheets or layers with a nonwoven (may be woven but non woven ...
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.

On the basement walls of a big business area with many buildings an elastic special drainage product was used. Drainage sheet called Enkadrain was elastic with 2 filter fabrics on both sides and has a drainage core between them. It was easy to cut and put it on the waterproofing. Liquid bitumen type waterproofing was used. So also the overlaps were glued with that waterproofing ...
