In which case should you think about drainage on the site?
Drainage should be done if the groundwater is at a depth of 2.5 meters from the ground level - the roots of the trees grow so much. If the depth of groundwater is lower, then drainage is not needed. Determine this depth can be an experienced way - to drill a trial hole.
You can do and it's easier - find out from neighbors how things are or see the condition of trees - if the high crown feels fine, you can calm down. If the soil is clayey, the area is sloping or is located on a slope and water flows intensively through it during the melting of snow - the drainage device is mandatory.
We organize the correct workflow
The drainage system in the cottage has its own characteristics:
- It is carried out before planting and building up - it is necessary to remove a large amount of land;
- Work must be preceded by a calculation;
- Drain wells are mandatory for revision of the system;
- The slope towards the spillway is respected from 2 to 10 mm, the pipes are wrapped with geotextile, and the trenches are sprinkled with gravel.
First of all, you need to determine the slope of the site - to see where the water drains after the rain. Drainage in the country with their own hands can be done using simple tools and materials:
- rack for checking the level of installation of pipes;
- shovel;
- garden wheelbarrow;
- pipe cutting knife;
- ramming;
- drains - plastic pipes with holes;
- corners for pipes;
- rotary shafts;
- geotextile;
- rubble.
Drainage consists of main and additional drainage trenches and catchment - a ditch or a well. The main trenches are oriented to the catchment area, additional ones are laid with a "Christmas tree".That is, the main trenches must end in a catchment well or ditch, and they should be placed with the future house and garden in mind, leaving room for them.
Stages of the organization of the drainage system in the country
After the marking, it is necessary to excavate the trenches. In clay soil - about 70 cm deep, in loam - about 90 cm, and in sandy soil - about a meter. How to make drainage correctly? First of all, you need to observe the necessary bias. For each linear meter of the system, the slope towards the catchment area should be from 2 to 10 mm. If the area is flat - the slope should be greater, if there is a natural slope - less.
Then you need to wait for a heavy rain or pour the entire system with plenty of water and check each section - whether the water runs off well. All areas where water stagnates should be deepened and corrected. This stage is a time-consuming, but necessary, properly arranged system that works without fail for many years.
Then we determine how to properly make drainage in the country - open or closed way, that is, we compact the trenches and leave them open without pipes, or still lay drains and close the system. An open system can be used with a lack of funds to finish later.
The device of drainage in the suburban area in full volume implies the final stage - the wrapping of pipes with geotextile, connecting the sections with corners and joining the swivel wells. It is necessary to watch, that the pipe lay in a pillow from rubble - so water passes without obstacles. On sale there are pipes already packed in geotextiles, this shortens the time.
Above, the pipe is also covered with rubble, and on top - a layer of earth with a mound, the ground will settle, and the surface will be leveled. Drainage of the suburban area with their own hands requires time and effort, but pays off with a blossoming view of the site, the ability to build and grow anything, as well as the wonderful time spent with family and friends.
