HOW TO MAKE A POOL

Work begins by determining the appropriate location for the construction of the pool. It is necessary to take into account the depth of groundwater. In areas where their level is located at a distance of 0.5-1 m from the surface of the ground, it is not recommended to erect a stationary concrete basin. It is undesirable to have the structure next to the foundations of the buildings on the site.
Further, they are determined with the shape and size of the future structure, while proceeding from the fact that the more complex the configuration of the basin and the larger its dimensions, the more funds will be required. From this point of view, ponds having a rectangular shape are cheaper. Such pools are easier to build with their own hands, we only need to carefully mark out the layout so that all sides of the structure correspond to the design calculations.

At the next stage, they begin digging the excavation. To speed up earthworks, it is better to attract special machinery, if, of course, its access to the construction site is possible. If there is a risk of collapse of the pit walls, they are placed under a slight slope towards the center. The bottom of the excavation should also be inclined towards the drainage pit. This will facilitate further drainage of water in the operation of the structure. Digging an excavation for the pool
Experts recommend to arrange additional drainage of the pit. For this purpose, in the middle, a small depression is made, which is filled with rubble. Then the bottom is covered with a sand layer, the thickness of which is from 20 to 30 cm. The sand is carefully compacted. After pour a ten centimeter layer of gravel on top of the sand, which also needs to be compacted. Do not forget to pack all the necessary drainage and liquid communications.
Next, pour the bottom with concrete, for the preparation of which take cement grade not less than 400. The concrete solution is poured into a five-centimeter layer. Above lay a reinforcing mesh, for the manufacture of which use a metal wire 6-8 mm thick. The grid cells should have a size of about 15-20 cm. The intersections of the grid elements are curled by a soft wire. On top of the grid, another layer of concrete mix is ​​poured, the thickness of which is also equal to 5 cm. As a result, the thickness of the bottom of the pool will be 10 cm. To ensure uniform drying of the concrete, it is wetted with water.
