Plastic Drainage Plate, Brand Name : Ruimin

Plastic drainage boards are made of polyethylene or polyethylene plastic base plates that are stamped into conical protrusions (or hollow cylindrical perforated plate). Plastic drainage boards are divided into two series: roll and sheet materials. In terms of shape, special techniques are used to press the plastic board out of the enclosed raised cylindrical shell, forming a concave convex film. The shell is continuous, with three-dimensional space and a certain support height. The top surface of the conical protrusion is bonded with a layer of filter geotextile to prevent soil particles from passing through, thereby avoiding blockage of the drainage channel and ensuring smooth drainage of the hole.
