Can These Boards Be Used Below Ground?

Yes, HDPE Dimple Drainage Boards are particularly suitable for many below-ground applications. They can be installed alongside basement walls, foundation structures, retaining walls, and other buried surfaces where water accumulation may create pressure or moisture concerns. The board establishes a drainage cavity that helps direct water toward collection systems. It can also protect waterproofing layers from soil contact and mechanical stress. For successful underground use, the board should be selected according to anticipated loading, drainage requirements, installation conditions, and compatibility with the complete waterproofing and drainage assembly specified for the project.
