Deep drainage - modern technology in the fight against waterlogging site

deep drainage - When necessary?

It is worth thinking about what your site needs a deep drainage, if it is swamped or in a place with excessive moisture.For example, if the site is located in a valley, that without a good drainage system can not do, because in the lowland will drain all the water from melted snow and rain.Before the construction of a residential house in the mandatory checks the level of groundwater.

If they occur deep enough, then there is a risk podmytuyu foundation of the house and all of the same area of ​​waterlogging, rotting roots of established plants, etc. Soil quality is also crucial, because if it is dominated by clay, even at low precipitation your site could turn into one big puddle.

So, if you find one or more of the factors determining the need for laying the deep drainage system, and decided on its installation, you will be able to solve the following important problem:

  • protection is not only the foundation of his house, and laid in the groundutilities.
  • Obstruction penetration of groundwater in the basement and basement premises.
  • Reduced humidity level not only in the region but also in the home, especially, at the ground floor.
  • Preventing soil washout, its swelling, subsidence and destruction of the landscape of the root system of trees, shrubs and other plants.
  • Reducing the risk of emergence and breeding in your yard pathogenic bacteria, insects (mosquitoes and black flies), and even frogs.

Closed drainage - its basic elements

So, underground drainage device is a set of measures aimed at laying buried in the ground perforated pipes to absorb excess moisture and installation of drainage wells for their service.In addition to drainage pipes and wells one of the main and most functional elements of the system are drainage tunnels.

They are designed to remove rainwater and filtering it before being discharged into the well.These tunnels contain in themselves a lot of water compared to gravel trenches, so their use in places parking area is most justified.

Modern drainage tunnels can withstand a load of about 3 tons per 1 m2!

However, the basis of the deep drainage system, though, is the pipe for drainage.Just a few years ago, they were made of ceramic or asbestos, but today it was replaced by a practical, easy and convenient to install plastic.Modern perforated pipes perform two functions simultaneously - and its receiving water discharge.

This ensures a proper water balance in your area, and minimizes the risk of adverse consequences associated with excessive soil moisture.If in the vicinity of your home there is a natural pond or other place where water can be discharged rejection, we can assume that you are lucky.The only nuance about which you have to take care - it is pre-treatment of water.

If such a receiver is not present, you will have to install the drainage wells. They are a special container, which deepened into the ground and absorb moisture collected by drainage pipes.

If your site is small in size, and degree of flooding is not too large, it is possible to do one a well. Otherwise, they may need a few pieces.With the help of drainage wells is not only the distribution of water in the system, but also to monitor its functioning.

deep drainage device - observe the implementation of the technology works

stacked subsurface drainage may, in accordance with a particular scheme.Most often, the pipe lay on the perimeter of the land, according to its center, or diagonally."Herringbone" Another way of drainage system of the device is laying pipes.This allows you to quickly and efficiently collect the water from the area of ​​the whole area, not allowing his waterlogged.

for laying drainage pipes need to dig a trench the appropriate depth.As a rule, it depends on the soil quality and the depth of the groundwater.For example, for clay soils optimal depth indicator tab pipe is 60-70 cm and for sand - about 1 meter.Trenching and pipe laying, respectively, is carried out under a slight downward slope towards the sump (drainage well) that allows water without any interference in it is easy to drain.

Before laying drainage pipes at the bottom of the trench lay sand and gravel "cushion"!

then deep drainage device involves filling pipes laid with gravel and sand.They poured excavated pre-ground, and laid the turf.Thus, you get an effective closed (hidden deep in the ground) of your site drainage system.Experts note that the drainage device, you may encounter some problems, but many of them are easy to handle, but will require additional costs.

For example, in the absence of the possibility of laying pipes under the slope will have to purchase and install a drain pump.But the costs will pay off rather quickly, and a quality drainage will delight you with its performance over time.
