Drainmat BG
DRAINMAT BG is an HDPE composite dimple board with a geotextile filter fabric, designed to efficiently allow water to pass through, providing both hydrostatic relief and protection of waterproofing materials from backfill such as soil, sand particles, or fresh concrete. Water is able to penetrate the fabric on all sides, while the dimpled core provides flow channels to pass water to the appropriate collection system.
Drianmat BG is an upgraded, cost-efficient solution to traditional dimple board products. The impermeable HDPE core makes it superior in strength and longevity, especially in brackish conditions, while the high compressive strength and high flow capacity make it the perfect solution for both backfilled walls and horizontal applications.
