In order to reap the effectiveness and durability benefits that metalled roadways with porous surfaces such as bridge aprons bring when it comes to drainage, they should become the automatic choice. Asphadrain is the answer. It is a drainage geocomposite designed to drain water that infiltrates the layer between the road surface and the concrete.
When Asphadrain is incorporated into an apron drainage system, it plays a specific role in collecting and evacuating surface drainage water.
