Land drainage - the main functions and tasks of
Basically, this system is being arranged to improve poor conditions for plant growth due to too high a level of groundwater. That is why this level should be adjusted and provide an obstacle to stagnation of water. For this, the drainage device is needed on the site.
Excess moisture is generated for various reasons. For example, clay soil or its high moisture capacity, the location of the land in the lowland or near any slope, too deep arrangement of the foundation of the structure and the absence of trees that strengthen the soil and absorb excess moisture can contribute to this.
A similar situation is detrimental to plants, which are constantly in moisture and do not receive enough air. The more groundwater can have a destructive effect on the foundation, constantly washing and destroying it. A wet cellar threatens the house with the appearance of mold, fungus and heat loss. Therefore drainage of the land plot is mandatory in all the above cases.
How to arrange drainage on a site - types of
systems The system device can have several types , each of which is characterized by its features and recommendations for the arrangement. For example, if there is sandy or sandy loam soil, then it is better to equip the linear system. It is necessary to use pipes as a drain.
Wall systems are used to protect underground structures that are threatened by groundwater flooding. They consist of reservoir drainage and pipes. If there is a powerful water layer under the building, then it is best to equip the reservoir system.
This variant is especially effective in soils of layered type with a weak permeability of moisture. Another presented system can protect the structure from capillary moisture. Therefore, before you arrange drainage on the site, you need to evaluate all of its possible parameters.
Before making a drain on the site, you need to determine the type of soil and learn how to properly carry out the procedure. Typically, a classic system consists of a waterproofing membrane, a sand prism and pipes that provide water drainage. The stages of work will be discussed in more detail below.
Area drainage - sequence of works of
Before making a drainage on the site, it is necessary to prepare. To equip the system you need a shovel, sand, gravel, waterproofing materials, pipes. Then you need to strengthen the waterproofing of the foundation: the surface of the base of the house is primed with bitumen, covered with reinforcing mesh, and after drying it is again ground with bituminous mastic.
The device of drainage on the site with their own hands is a simple matter, but the procedure should be carried out in stages. First, the necessary inclination of the system is provided( all the ground changes are adjusted to the level).Further, sand, geotextiles, gravel are laid on the bottom of the dug trench.
In gravel it is necessary to make a small groove into which the pipe( perforated) is placed.
In the pipes, it is necessary to drill the holes so that the water can enter and exit. The elements are joined after the final slope check. And in order to wash the system, it is necessary to put several vertical outlets.
Next, the pipes are wrapped with geotextile, and the system is filled with sand. If there is a need to increase the filtering surface, then a layer of gravel should be poured in front of a layer of sand. About the drainage of the site with the hands of the video can be found at the end of the article, so if you need a visual aid for the arrangement, take this opportunity.
