Dimple Drain board is made by 100% pure HDPE, 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.

Plastic drainage boards are lightweight, high-strength, and have excellent drainage capabilities, effectively preventing water accumulation in soil and structures, thereby reducing water pressure. They are widely used in underground projects, green roofs, and slope drainage, enhancing soil stability and the durability of the engineering structures.
