Description

Introduction

The water storage and drainage board is made of polyethylene plastic injection molding. It is a new kind of drainage fabric that integrates drainage and water storage functions. It additionally has a couple of features such as water storage, drainage, ventilation, insulation, and root resistance (preventing plant roots from destructive concrete structures). When mixed with geotextiles, it can stop great particle matrix from blockading water storage tanks and drainage channels, keep clean drainage and air circulation, and shape a entire and new kind of water storage and drainage system, which is extensively used in city landscaping projects.

Working Drawing

After the building of the water-resistant layer and its shielding layer is completed, begin 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 formed mouth going through upwards and the tooth interlocked;
3. Cover the drainage board with geotextile, overlapping 10-20cm to forestall mud and water from passing via the geotextile, clogging the water storage and drainage system, inflicting terrible drainage and decreased water storage capacity;
4. Lay 10-20mm medium coarse sand on the geotextile to structure a permeable filter layer, which can forestall the loss of planting soil;
5. Cover with gorgeous thickness of planting soil.
6. It is critical to make sure the safety of completed drainage boards.
