Drainage Board
Drainage Board is a protective material used in construction to manage water around building foundations and walls. It's like a plastic sheet with dimples or channels that creates space between the building and surrounding soil, allowing water to flow down to drainage systems instead of pressing against the structure. People might also call it foundation drainage board, dimple board, or waterproofing membrane. This product is essential in preventing water damage and maintaining dry basements and foundations. Think of it as a rain jacket for buildings that helps water move away from the structure.
