Product Description

Introduction

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

Drainage board designed for vertical / horizontal applications at shallower depths where moderate compressive strength and flow capacity are adequate.
1. Water Drainage, Drainage board abon be used in combination with non woven to get rid of the rain immediately and effectively relieve the roof's pressure caused by the instanteous rainfall.
2. Ventilation, Special design helps the plant layer to have good air-ventilation ability at the bottom, improves ventilating situation and ensures the oxygen demand for root.
3. Environment Protection, It is 100% recyclable, won't cause secondary pollution to the environment.
4. Safety & Light Weight, Plastic storage and drainage plate's light weight will not enhance load for roof structure. It required no cranes or lifting equipment.
5. Water Storage, Absorb and store redundant moisture leaking from the planting layer and supply needed moisture for the plant when the soil lacking of water to improve plant's drought-resistance ability.
6. Heat Insulation, The storage place for the Drainage Cell is at the bottom of the plant, helping the plant to stop from the sun direct illuminating and form a cool space, which can absorb heat from structure layer to form air troposphere.
7. Low Price & Quick Installation, Ultra-light weight, easy installation, quick construction, low construction cost and simple maintenance.
