waterproofing HDPE drainage dimpled membrane
Product introduction
HDPE dimple drain sheet/ drain matting/ drain board/ cavity drains/ drainage membrane for waterproofing of railway tunnels, road base, foundation floor, building basement top, retaining wall and roof drainage. It is produced by railway standard hdpe material, virgin material. Plastic HDPE dimple drainage board is the use of foundation or blow molding method to produce high density polyethylene (HDPE) geomembrane, pressed on geomembrane pressure after the special craft the closed swelled the frustum of a cone shape, having a three-dimensional space and some support stiffness,liquid, gas can flow excreted within its plate.
