Description

Introduction

A Composite Drainage Board is a kind of drainage machine used in building and civil engineering projects. It is usually made up of more than one layers of substances designed to successfully manipulate water runoff and forestall waterlogging in a number of applications, such as inexperienced roofs, keeping walls, underground structures, and landscaping projects.

Drainage board is the board with stiffened concave-convex hollow-structure nub produced by way of nice high-density polyethylene in the science of warm melting and extrusion. The product ought to discharge rainwater shortly and effectively,greatly decrease or even dispose of the hydroststic strain of water-resistant layer,the essential welding ought to additionally advantage water-proof layer,the crucial welding should additionally gain waterproof.This initiative drainage principle should gain initiative water resistant effect.

Working Drawing

After the development of the water-proof layer and its protecting layer is completed, start laying the drainage board. Require the slope of grassroots drainage to meet a vary of two ‰ to 5 ‰;
2. Lay the drainage board with the cup fashioned mouth going through upwards and the enamel interlocked;
3. Cover the drainage board with geotextile, overlapping 10-20cm to stop mud and water from passing thru the geotextile, clogging the water storage and drainage system, inflicting negative drainage and decreased water storage capacity;
4. Lay 10-20mm medium coarse sand on the geotextile to shape a permeable filter layer, which can forestall the loss of planting soil;
5. Cover with splendid thickness of planting soil.
6. It is indispensable to make sure the safety of completed drainage boards. After the set up of the drainage board, it need to now not be allowed to at once push hand carts on the drainage board. When transp
