Drainage boards allow water that has reached the walls of a structure to flow harmlessly away. Without drainage boards, water can saturate a building’s walls or pool around its foundation. ArmorDrain 400 Drainage Mat provides commercial and residential buildings alike with drainage protection at a value price. The board is formed from a heavy-duty, high-density polyethylene drainage core which is impenetrable to water. The drainage core is molded into durable ridges and bonded to a single layer of non-woven filter fabric.

ArmorDrain 400 Drainage Mats are designed to provide drainage in extreme cases involving heavy loads or heavy traffic, such as under slabs, planters, retaining walls, bridge abutments, foundation walls and roof gardens. The heavy fabric prevents rocks and dirt coming entering the drainage channels. The result is a cost-effective addition to a drainage system which reduces hydrostatic pressure, allows water drain away from foundations and protects waterproofing membranes. ArmorDrain 400 Drainage Mat is also easy to install, and can be fastened directly to concrete.
