The order of work on the drainage device around private homes , types of drainage systems

Many homeowners believe that the presence of waterproofing completely covers the issue of protecting basement and foundation from the effects of groundwater.And some of them are quite right, but only on condition that their house is on the sandy ground.

However, this option is only happy exception, as most of the households in our country is located on the loamy and clay soils where the groundwater level is high enough.If the land was in the valley, the puddles on it will stand even in the summer, so do not do without the drainage devices around your home.

Types of drainage systems

Before starting work, you must determine the type of drainage.Drainage systems, which can be fitted outside the house may be of three types:

• Open systems, drainage of which is carried out by tearing open trench about two feet wide and deep.The advantage of such systems is that such drainage is quite easy to accomplish on their own.However, the open trench dug at the site, look unsightly and pose a danger of falling into them.
• Charging systems consisting of trenching depth from 0.5 to 1.5 m, covered with broken bricks, large rubble, Booth and covered with turf.The advantage of this system is its high durability.The drawback is the impossibility of maintenance during operation.
• Closed systems where drainage is done with the help of pipes lying on a layer of gravel, fill in the trench depth of about two meters.This method is most prevalent, is not the shortcomings of the previous two options.Let us dwell on it in more detail.

order of arrangement of drainage

To equip yourself drainage near the house, you must have a shovel, wheelbarrow, hacksaw, hand rammer and building levels, laser or bubble.

Drainage around the house start to equip with that trench encircling the foundation.Their width should be about half a meter, and they must lie in the 10-20 cm below the base of the foundation.The corners of the trench must be round so as to enable the correct pipe laying.

From annular trench dug around the basement, you should open up to the lowest point of the site other trench.At this point, you should dig a hole and set it well in plastic.Otvodnaja should dig a trench with a minimum slope of 1 cm per meter of its length in order to drain by gravity occurred.

bottom vent trench to fill with sand about 5 cm thick, keeping the bias inherent in it and carefully tamped this layer.At the bottom of the ditch and the wall along its entire length to lay geotextile.Where it webs connect, the overlap should be at least 15-20 cm. Then pour a layer of gravel about 10 cm thick and place it on a perforated tube, if necessary bonding locations in docking with a special tape.

In two of the most far-flung corners of the house, you must install manholes, which made docking tubes via fittings.In operation, data wells may be needed to eliminate blockages and to determine the water level.

Laid pipe covered with a layer of gravel 40 cm thick, wrap this layer of geotextile fabric to the sides of the trench to separate the gravel and cover it with soil to prevent silting of rubble.Top should be laid discharge pipe stormwater.Because the pipe dock with livnevki should not be perforated, the water from it in a trench will not do.

Both pipes laid in a trench in such a way, should go into the drain well, where there is a drain in the roadside ditch.Trench fill up with soil and cover with prepared turf.
