Capillary drainage board is a cross drainage board made by extrusion molding of high-density polyvinyl chloride material, which fully utilizes the material characteristics of high density, high strength, and amorphous structure of PVC material. It adopts a patented design of cross support columns and a top column added in the middle, utilizing the large plane of the support columns and the arrangement of the middle top columns to ensure that the geotextile does not sink after covering the soil, leaving sufficient drainage and unobstructed space. At the same time, the cross support column has eight reinforcing bars of different sizes, greatly increasing its compressive strength.
The product has a fixed width and can be customized in length according to needs. The construction auxiliary equipment is convenient, and after the auxiliary equipment is completed, a new waterproof layer and root layer are formed.
