Drainage Boards

Drainage boards is divided into two series: coil material and sheet material. Among them, the coil is divided into three types: “hot melt”, “lap joint” and “self-adhesive”. In terms of shape, a special process is used to press the plastic sheet out of a closed and convex cylindrical shell to form a concave-convex film with three-dimensional space and With a certain support height, the top of the shell is covered with a geotextile filter layer for water seepage, hydrophobicity, drainage and water storage. Also known as: self-adhesive PE drainage board, drainage board, drainage protection board, water filter board, plastic bump drainage board, plastic sandwich board.
