drainage system protects the building from the basement flooding and damage caused by snowmelt, stormwater or groundwater.Drainage of the foundation can be trim and formation.Trim consists of perforated drainage pipes laid along the perimeter of the structure in the trench.Formation drainage air gap is disposed around or underneath the foundation.He arranged with the help of special drainage materials (plates, membranes) or a layer of gravel covered with geotextile.The reservoir drainage is recommended to focus on areas with complex hydrogeological conditions (eg, artesian groundwater).In all other cases, you can do near-wall version.If necessary, take only rain and meltwater from the loamy and clay soils arranged melkozaglubnenny drainage (storm sewer system).

drainage methods: Formation and trim the basement of a private house drainage

foundation drainage device is as follows: Perforated pipe laid in a layer of gravel around the foundation.To ensure the water drainage by gravity, the tube mounted
at an angle.Pipes are displayed off-site or in the special collector wells.It is advisable to use drainage pipes with a filter of geotextile, which prevents silting and clogging the holes in the pipes.

Prifundamentny drainage is melkozaglublenny and depth.Drainage melkozaglublennogo strip foundation - it's the same storm water drain, consisting of pipe located in the upper soil layer.This drainage collects and diverts the water drained from the roofs (linear) and roof catchments (point).Melkozaglublennye systems are effective only for clay and loamy soils with poor absorbency.Deep drainage is more popular, it is used for buildings constructed on soils with closely spaced aquifers.Perimeter drainage collects and removes dirt, rain and melt water rises close to the line of foundation to prevent the flooding of basements.

Plast drainage is recommended for problem soils with a layered structure vodonosnosnogo horizon or for areas with artesian groundwater.Formation drains are often used to protect against drowning important facilities (library holdings, museum storage, etc.).This type of drainage system is a filter pad, laid at the base of the foundation.For drainage layer device can use special drainage platform membrane, geogrid.A cheaper option - a mound of gravel, closed geogrid.The latter option, despite a reasonable cost, have several disadvantages.And chief among them - a fast strain under the weight of the foundation.

Video instruction on how to make the drainage of the foundation with his hands

Let's look at how to make their own drainage.The algorithm works can be viewed on the drainage of foundation with his hands video.The approximate scheme of drainage of the foundation is as follows: perforated pipe in the filter layer of crushed stone, angled and bred in the collector well, or just outside the area.The system should be equipped with rotary wells, allowing units to clean the pipes from clogging and siltation.

device for drainage around the perimeter of the building (at a distance of 1 m from the base) dug trenches.Their width should exceed the pipe diameter 20 cm, depth depends on the foundation.The system can function properly only if the tubes are located 0.5 m below the bottom point of the base.Trenches pillows compacted sand, over which is laid geomaterial.The next step - the creation of mounds of gravel and pipe laying obliquely.Pipes connect fittings with a press fit with the mandatory Retake insulating tape.On top of a mound of pipe another layer of gravel.Finally, the edges are wrapped and stitched geomaterial.As seen from the foundation drainage video, in some cases, the construction of the drainage system can be avoided if instead of a belt stop on the pile foundation.
