So that such a design is as functional as possible and for a long time pleasing the eye, it is necessary to observe some rules for its construction. First of all, it is necessary to make sure that drainage is arranged between the slope and surface of the wall. For this, coarse gravel or gravel is usually used. To increase the efficiency of the functioning of the drainage system, a drainage pipe should be lived on the lower layer of drainage (you can use steel water and gas pipes). For this pipeline, precipitation will freely be displayed outside the support wall.
Features of the design of the retaining wall directly depend on its height. If the wall height exceeds 0.8 m, then it should be slightly (10% – 15%) to dodge the slope. The upper edge of the retaining wall should be slightly above the slope. This will help to avoid water overflow over the edges of the wall during the rain.
