Basement drainage of a congress hall building construction

Geocomposite drainage sheets can also be used in higher depths. Photographs here shows some applications of drainage composites. They are ready to backfill. The backfill around the composites should be made very carefully because of the height. Direct flow of gravel and backfil materials may tear or damage the drainage materials.

This drainage composite was placed on the waterproofing layer.
