The use of drainage board grid, non-woven geotextile, can generate an excellent overhead layer, so that unnecessary rainwater and irrigation water are going, and the drainage board can reasonably prevent the growth of plant roots and play a root-blocking role. The drainage board is made of high-density poly (HDPE) and polypropylene (pp), which is molded by heating and pressing to produce a light-weight sheet that has a drainage channel with corresponding three-dimensional space support strength and can store water. It is easy to construct, and it is the key to planting roofs.

The role of drainage board.

The key role of drainage board is to have water conductivity drainage, anti-drainage protection board have the concave and convex hollow standing rib structure, can quickly and reasonably export rainwater, reduce or even eliminate the hydrostatic pressure of the waterproof layer, according to this type of active water conductivity principle can do the actual effect of active waterproofing.

Anti-drainage protection board can reasonably protect the house building and waterproof layer, and it resists various acids and alkalis in the soil layer and the root thorns of plants. The practical effect of the overhead of the drainage board, which can isolate the heat, is obvious for the benefits that can be brought by the balcony.

How to create the landscape of the balcony.

The first step; do a good job of underground drainage problems, do a good job of underground waterproofing and then lay a layer of drainage board

The second step; spread a layer of geotextile to avoid the flow of soil and stones, water can drain away

The third step; according to the size of the area is divided into a good planting area, first with a good partition tile, set up a good shape

The fourth step; the main tree plants in place, large plants pay attention to the ornamental surface, more from multiple angles to watch

Drainage board project construction precautions.

1、Remove the garbage, cement and level the site so that there are no significant hard blocks on the site.

2、The bottom layer of the basement is impervious to water, and the bottom layer is on the upper side of the foundation base.

3、When laying drainage board in any area, care must be taken not to let the soil layer, cement, sand and other garbage enter the front space of the drainage board to ensure that the space of the drainage board is not obstructed.
