What is a drainage composite?
A drainage composite is an all-in-one system that combines a dimple core and a nonwoven geotextile fabric.
The three-dimensional core is manufactured from a polypropylene sheet that is cuspated under heat and pressure. The resulting dimple core is bonded to a nonwoven filter fabric. The resulting composite product allows for directional flow while retaining soil and backfill.
