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.
This is a latent many functions materials, the use of this plate can be easily constructed out of the overhead layer, using overhead layer formed drainage, exhaust passage, at the same time to use the overhead layer reaches low noise, vibration isolation function; drainage drain board water permeability in the field of civil construction can be widely used in the overhead layer of roofing systems, roof planting, drainage protection building basement waterproofing system, and interior.
