Everyone who has purchased his own house knows that the maintenance of the building and the adjacent area in perfect condition requires a number of systems and various communications. Here it is impossible to overestimate the importance of the drainage system. Naturally, all buildings must be protected from flooding, so the drainage around the house is an actual topic.
Before deciding to make drainage around the house yourself, you need to determine how it will be. There are three types: open, vertical and trench.
Drainage
Types of drainage - open drainage
Clear view is the easiest to perform. To arrange it, it is necessary to dig the drainage ditches along the designated perimeter, the functional value of which is the collection of water on the site. Open ditches are well "functioning" on the site, if it is on flat terrain. Those surfaces where the gradient is observed are excellent for drainage using pipes. The water collected in the ditches, eventually evaporates or is diverted to the water basin.
Open drain
Vertical drain
Vertical drainage is often called walled, as it draws water from the foundation of the building to prevent flooding of the basement of the building. The location of the pipe in this case is located below the floor in the basement. This kind of drainage is very reminiscent of an open system. The main difference is the need to dig a foundation for the width of the former pit. In addition, it is necessary to install a clay lock with a width of 0.5-1 meter. In addition, in the total mass of work on the construction of vertical drainage increases by the amount of additional excavation.
Vertical drain
Trench drainage
The next type of drainage is trench. The most common way of draining is laying drainage pipes. They can be made from a variety of materials, but the best option is a special drainage perforated pipe. Its use makes it possible to abandon additional hardware, avoid technical limitations during the execution of work, and also very quickly and simply lay the drainage pipeline.
Start of preparatory work.
Before making a drain around the house, it is necessary to perform a number of activities. First, it is necessary to primer the outer surface of the basement with a bitumen-kerosene solution. Over this, it is necessary to apply a layer of bitumen mastic with a spatula. Without letting the mastic solidify, it reinforces the reinforcing mesh made of fiberglass.
After a day, as the first layer of the coating dries, the surface needs to be re-processed with mastic to hide the mesh.

Before making a trench drainage around the house, you need to prepare the base. With the help of a laser level, it is necessary to measure all the altitude differences and install the poles in these places. On the marks made sand is poured, providing the necessary slope of the pipeline. Such measures provide an opportunity to ensure the correct diversion of water into a specially constructed drainage well.
On the prepared base, it is necessary to lay a special geotextile cloth on which the washed gravel is poured. In the poured layer of gravel is a groove, where the drainage perforated pipe is laid.
Drainage pipes are connected and the uniformity of the slope is checked with the help of a stretched cord.
Vertical pipes are installed at each turn of the pipeline. This makes it possible to flush the system. The pipes are closed with dense lids and carefully wrapped with geotextile. The material is fixed on the pipes using polypropylene or kapron lashing.
To increase the filtration surface of the drainage, its surface must be covered with a layer of gravel of 20 cm. Around the gravel, the geo-panel turns around. The final filling of the drainage system is carried out by river sand, which acts as a drainage filter.
Install a drainage system well.
Where a drainage branch is connected, a precast well is installed. The most common use of reinforced concrete rings. Ground for the base is selected at the intersection of the drainage pipes. In the process of backfilling, the insulation of the domestic sewerage with foam is a prerequisite.
