HDPE Dimple Drainage Board is a waterproof plastic drainage sheet widely used for foundation protection and landscaping drainage systems. It is manufactured from 100% pure high-density polyethylene (HDPE) using advanced blow molding or extrusion techniques. The board features a unique three-dimensional dimple structure, where each dimple is shaped like a truncated cone with a closed top.
This special design creates a stable three-dimensional space that provides excellent support stiffness while allowing liquids and gases to flow freely within the drainage layer. The dimpled surface efficiently channels water away, preventing water accumulation and ensuring effective drainage and waterproofing performance. The HDPE material offers outstanding chemical resistance, durability, and long-term stability, making the drainage board ideal for various civil engineering and construction applications.
