concept of the drainage system

Before you ask - and whether drainage is needed at home, let's understand that the meaning of this concept. site drainage system - is a branched network of pipes beneath the ground (under the construction area).

Its main purpose is to remove excess moisture from the soil.Water flows from the drain pipes in the soil, and further enters into a special receiving water (well) which is an important element of the system and must be located in its lowermost point.

If drainage is made incorrectly or not done at all, it will bring serious damage to a house foundation, and plants.The fact that water accumulates winter begins to freeze, and this leads to deformation of the foundation (cracks appear).In addition, moisture can enter the basement, cellar, garage inspection pit.

a result, will apply the processes of decay, the development of mold and mildew.Plants in the garden area can also die from excessive moisture.Vegetables planted on beds, just do not die before their maturity.List the problems of flooding can be infinitely more important to understand at once - whether the system needs to built-up area, and how to design it.

In some cases it is necessary to use drainage?

  • When the land is located in areas with high groundwater levels.
  • In case portion consists largely of clay soils (especially during precipitation).
  • If there is a need to challenge the melt water in the spring season.

When designing the system takes into account features of the soil and climatic conditions.When visiting the area, take the figures on its slope, depth, diameter and distance between soil layers.In particular, it is important to familiarize yourself with the rules of SNP.Drainage made to these standards will be of high quality and reliability.

Required data for the project: hydrogeological conclusion (or the conclusion.), Site plan in scale 1: 500, the foundation plans to sweep (it cuts), basements, organizing relief project plans underground channel sections.Plus should be given some of the characteristics of groundwater and soil.Only after the complete collection of all the data is determined by the type of drainage system for a specific site.

types of drainages

Conventionally the system can be divided into the following types: open, closed and deep .The simplest is considered first - open system or otherwise it is called a drainage ditch.It consists of ditches, slightly recessed into the ground.Each of them has a size of 0.6 meters wide and 0.5 meters deep.Further, these ditches derive water ditch in general (for multiple hosts).Open drainage will only get rid of the surface water and does not solve the issue with the problem areas.

Closed system involves laying pipes at a depth of about 1.8 meters, while the width of the pipe is only 0.25 meters.The ramifications of the tubes in the roll of geotextile, poured gravel and sand, and then the ground.This type of drainage is able to gather a significant number of water, but will not solve the problems with wet areas or located in a valley.In such cases, do deep drainage .

Over tab and the design of the system are working engineers, hydrogeologists.Pave trench 20-30 centimeters from the required depth (determined individually).In the trench lay sand pillow, and then lay the pipe.From above they are covered with geotextile and sand.Slope systems make towards a well or water intake, which may be a pond, lake or a ravine.If the water intake is not present, then make a well, located at the lowest point of the system.

Attention!The depth of the system is not recommended to perform with his own hands.Design and installation should carry out specialized experts.Drainage, laying videos are presented at our site, to help resolve issues with problem areas.
