All buildings are susceptible to water damage. 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. GeoMat Type I / “C” Drain Drainage Board is designed to provide buildings with drainage protection at an economical price point. The board is formed from an impermeable polymeric sheet, which is heated to form a dimpled drainage core. The core is then bonded to a single-layer of non-woven filter fabric.
GeoMat Type I/ “C” Drain 110 Drainage Board are designed to allow water to drain through channels created by the dimpled core, while protecting a foundation’s primary waterproofing membrane from damage by soil and sediment. The 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. Type I Drainage Board is easy to install, and can be fastened directly to concrete in prior to backfilling.
