Description

Introduction

Drainage board is the board with stiffened concave-convex hollow-structure nub produced by using pleasant high-density polyethylene in the technological know-how of warm melting and extrusion. The product ought to discharge rainwater rapidly and effectively,greatly decrease or even put off the hydroststic stress of water-resistant layer,the indispensable welding should additionally advantage water-resistant layer,the vital welding should additionally gain waterproof.This initiative drainage idea ought to obtain initiative water resistant effect.

Working Drawing

Drainage board designed for vertical / horizontal functions at shallower depths the place reasonable compressive power and glide ability are adequate.
1. Water Drainage, Drainage board abon be used in aggregate with non woven to get rid of the rain right away and efficiently relieve the roof's strain precipitated through the instanteous rainfall.
2. Ventilation, Special diagram helps the plant layer to have accurate air-ventilation potential at the bottom, improves ventilating state of affairs and ensures the oxygen demand for root.
3. Environment Protection, It is a hundred percent recyclable, might not purpose secondary air pollution to the environment.
4. Safety & Light Weight, Plastic storage and drainage plate's mild weight will no longer decorate load for roof structure. It required no cranes or lifting equipment.
5. Water Storage, Absorb and keep redundant moisture leaking from the planting layer and provide wished moisture for the plant when the soil missing of water to enhance plant's drought-resistance ability.
6. Heat Insulation, The storage location for the Drainage Cell is at the backside of the plant, supporting the plant to cease from the solar direct illuminating and structure a cool space, which can soak up warmth from shape layer to shape air troposphere.
7. Low Price & Quick Installation, Ultra-light weight, handy installation, speedy construction, low building value and easy maintenance.
