The drainage plate is divided into two series: coil and sheet. The coil is divided into two types: "hot melt" and "lap joint". The plastic sheet is pressed out of the closed and convex cylindrical shell by a special process in the shape to form a concave-convex shape. The membrane and the shell are continuous, with a three-dimensional space and a certain support height. The top of the shell is covered with a geotextile filter layer, which is used for water seepage, drainage, drainage and water storage products. Also known as: drainage board, drainage protection board, water filter board, plastic concave-convex drainage board, plastic sandwich board.
