Description

Introduction

A Composite Drainage Board is a type of drainage system used in construction and civil engineering projects. It is typically made up of multiple layers of materials designed to efficiently manage water runoff and prevent waterlogging in various applications, such as green roofs, retaining walls, underground structures, and landscaping projects.

Drainage board is the board with stiffened concave-convex hollow-structure nub produced by quality high-density polyethylene in the technology of hot melting and extrusion. The product could discharge rainwater quickly and effectively,greatly reduce or even remove the hydroststic pressure of waterproof layer,the integral welding could also benefit waterproof layer,the integral welding could also benefit waterproof.This initiative drainage theory could achieve initiative waterproof effect.

Working Drawing

After the construction of the waterproof layer and its protective layer is completed, start laying the drainage board. Require the slope of grassroots drainage to meet a range of 2 ‰ to 5 ‰;
2. Lay the drainage board with the cup shaped mouth facing upwards and the teeth interlocked;
3. Cover the drainage board with geotextile, overlapping 10-20cm to prevent mud and water from passing through the geotextile, clogging the water storage and drainage system, causing poor drainage and reduced water storage capacity;
4. Lay 10-20mm medium coarse sand on the geotextile to form a permeable filter layer, which can prevent the loss of planting soil;
5. Cover with appropriate thickness of planting soil.
6. It is necessary to ensure the protection of finished drainage boards. After the installation of the drainage board, it should not be allowed to directly push hand carts on the drainage board. When transp
