Drainage systems on the site

The construction of residential buildings in the private sector and outside the city is usually associated with the danger of groundwater located close to the surface. There is also a risk in the water under the turf, which can cause the death of green spaces, damage to the foundation or basement. Excessive humidity is often characterized by low-lying areas, as they are prone to waterlogging if preventive measures are not taken.You can't do without drainage if:- the level of the basement or technical floor is below the groundwater level;- the house is located at the foot of a hill (stormwater flows down the slope to the site);- on the land plot, the soil is clay or loamy, which practically does not allow water to pass through.According to experts, about 60% of problem areas are in private construction.Drainage works. Their features, first of all, it is necessary to protect residential premises from flood, meltwater, stormwater and groundwater by drainage at the walls, thus it is possible to extend the duration of operation of building structures, isolating them as much as possible from water ingress. After that, the land plot should be equipped with drainage trenches and drainage pipes should be laid. In order for the water collected by the drainage system to concentrate in a certain place, it is necessary to dig and strengthen a well or divert water to a nearby reservoir.To get acquainted with the description of drainage works in more detail, you should refer to the literature, which describes the construction of drainage and drainage devices and structures. We recommend the book "Drainage and wastewater treatment", written by V.S. Samoilov, as well as GOST 8411-74 and 1839-80. Novice enthusiasts need to devote some time to studying the theory, since it can be used to solve problems that they will later encounter in practice.Types of drainage, according to their device, there are 3 types of drainage systems: reservoir, wall and ring.The cheapest option is open drainage due to ditches that can be dug on the border of the land plot. It is necessary to save wisely, ordinary trenches can cause increased injuries.It is worth considering a safe backfilling option as an alternative, in which an inclined layer of gravel is formed under the turf with a thickness of 10-15 centimeters. Due to the porosity of the layer, water drainage is ensured.Another popular option is a closed drainage system, in this case a special pie is used to hide the pipes, and the channels are filled in.For example, for wall drainage, you should dig a trench about 2 meters deep along the entire perimeter of a structure or building. At its bottom, it is necessary to pour sand and tamp it well, adhering to the slope of the bottom - 1-2 centimeters per meter. Then granite rubble is poured 20 centimeters thick and a drainage pipe is laid, forming another layer of rubble. In conclusion, this "pie" is supplemented with geotextile (despite its small thickness, it has good strength, it does not decompose under the influence of water) or another filtering analog to protect the crushed stone from flooding and clogging with alluvial soil. Eventually, the trench is filled with earth.Reservoir drainage is installed under the house. It is built to protect basements and technical floors (below ground level). It can be used both independently and in combination with other drainage systems. When choosing a combined option, reservoir drainage should be combined with pipes from drainage systems located outside. It is advisable to build such a drainage if the house is located on heavy soil that does not allow water to pass through or if there are springs or keys in the ground.Reservoir drainage is a layer of sand above the pipe drainage. Sand is laid out throughout the territory, its edges should go beyond the boundaries of the foundation being erected. The thickness of the drainage layer is selected based on the characteristics of the soil. Bahisbey Casinos Canlı Bahis <br>
