Product Introduction

PVC drainage board is made by extruding high-density polyvinyl chloride material, which fully utilizes the high density and strength of PVC material A cross shaped drainage board made of material characteristics such as amorphous structure. It adopts a patented design of cross support columns and a middle top column, which is formed by arranging the large plane of the support columns and the middle top column to ensure that the geotextile does not sink after covering the soil, leaving sufficient drainage space. At the same time, the cross support column is reinforced with eight different sizes, greatly increasing its compressive strength. The width of this product is fixed and the length can be customized according to needs. It is easy to construct and lay, and after the laying is completed, a new waterproof layer and a barrier layer are formed.

Product advantages:

PVC drainage board adopts a structure of supporting columns and middle top columns based on mechanical principles. Through the combination of high and low columns, the geotextile does not sink after covering with soil, ensuring sufficient drainage space. Strong root resistance. Due to its high density, PVC drainage boards have strong root separation properties, and the thickness of the film can be adjusted according to the root separation requirements to achieve the root separation effect, with strong tear resistance. High compressive strength, PVC drainage board has a high compressive strength, which is 1.5 times that of PS roll of the same thickness and 2.5 times that of HDPE material. The compressive strength of PVC H20 drainage board with a thickness of 0.7mm should be increased to 300kpa On the other hand, the compressive strength of PS and HDPE materials with the same thickness is only about 150kPa. Due to its unique reinforcement design structure, cars generally do not flatten any of the support columns when driving straight on top. This is something that other PS and HDPE materials cannot achieve. It can be bonded and hot pressed. Due to the amorphous structure of PVC material, the use of special adhesive can effectively destroy the surface structure of the material, thereby enabling the two-layer film to be effectively bonded

Dissolve together to achieve waterproof and root blocking function after construction is completed. Mechanical hot stamping can also be used. Secondary waterproofing function: After the drainage membrane is laid, a new waterproof layer is formed by bonding or hot stamping, which has both drainage and secondary waterproofing functions.
