Armourflow is an advanced geocomposite drainage board. Protects waterproofing coatings and channels water efficiently to the drainage system, preventing hydrostatic pressure build-up. Armourflow is comprised of a dimpled high crush resistant plastic core with a geotextile filter bonded to the core. It provides a drainage sheet that can collect and filter water ingressing from backfill soils.

Armourflow can often be used to replace conventional mineral drainage aggregate and saves time and money due to its light weight structure and quick and easy installation without the need for heavy machinery.
