Dimpled drainage board is also called “Building Sandwich Plastic Board”. It is made of HDPE or PVC plate through stamping, which is finally a plate with conical dimples. Our dimpled products including HDPE single side type and HDPE/PVC double side type, without holes or one side with holes at the top. Good drainage system is very important to the construction period and the normal usage of surrounding building. Together with porous water pipe, or non-woven geotextile, dimpled drainage board can form an effective drainage and saving system. It can also greatly reduce the hydrostatic pressure of the waterproof layer, and reach the result of initiative waterproof. By the reliable joint method, dimpled drainage board becomes a suitable waterproof adminicle.
