Advanced Drain® is our multi-purpose drainage and ventilation mat used in a number of applications. Available in .125”, .25”, .4”, and .5” thicknesses, these drainage composite mats consist of parallel geometric drainage channels backed with a nonwoven filter fabric designed to eliminate hydrostatic pressure from behind below grade foundation walls, retaining walls, and planters.
Advanced Drain® is produced from an extruded polymer matrix of randomly entangled monofilaments. The polymer matrix is then shaped into a series of parallel channels designed to allow air and moisture flow in all directions. A nonwoven filter fabric is then heat bonded to the entangled net to prevent soil from entering the matrix of the system, while providing ample air and moisture flow.
