Below Grade Drainage Systems
ABP Advanced Drain® .250
ABP Advanced Drain® .250 is a 0.25 inch thick drainage composite consisting of parallel geometric drainage channels backed with a nonwoven filter fabric designed to eliminate hydrostatic pressure from behind below grade foundation walls, retaining walls, planters and plaza decks.
The product is produced from an extruded polymer matrix of tangled randomly oriented monofilaments. The polymer matrix is then shaped into a series of parallel porous channels designed to allow flow in all directions, and then attached (heat bonded) to a polyester nonwoven filter fabric designed to prevent soil from entering the matrix of the system while providing ample flow of water.
