DrainMax prefabricated drains combine a formed polymeric drainage core with a filter fabric bonded to one side. The filter fabric is bonded to each dimple to prevent soil intrusion into the core flow channels while allowing water to freely enter the drain core. The core provides an uninterrupted path for water to flow to designated drainage exits.
The GMX DrainMax Sheet and Base Drain are an economical solution for reducing hydrostatic pressure against structures and protecting and enhancing the life and performance of waterproofing membranes.
