How to make the drainage around the house or prevention of dampness in the area

How do drainage around the house and why is it important?

It often happens that people, to build a private house and make waterproofing think that protect your foundation or basement of groundwater.Indeed, when the ground on which the house is built, is composed mainly of sand, there is a high probability that it will be so.

Unfortunately, the majority of private homes in our country is built on clay and loam soils, in addition to the high water table, but if the site is located in a valley, then it may even be a puddle of water in the summer.

But the worst start in the winter, when the water pressing on the foundation, under the influence of negative temperatures starts to freeze and destroy the waterproofing.

spring, after the melting of the snow mass, the cellar, as a rule, begins to heat a little, and still more every year, and on the walls appear fungus and mold.And only then the owner realizes that he is no longer nothing left to do and drainage, which serves to drain excess water.

Drainage home with their own hands - what we're dealing with?

Drainage systems are divided into three types.

  1. Open .Drainage takes place via the open channel width of about two feet and a depth of 0.5-0.7 meters.The main advantage lies in the fact that the drainage around the house with his own hands to do quite easily.However, an open ditch is very spoil the view area, not to mention the fact that they can accidentally fall.
  2. Sediment .In this system, the drainage ditch digging to a depth of 0.5-1.5 m, backfilled Booth, large rubble, broken bricks and covered with turf on top.The advantages of this system include high durability (especially after the appearance of the geotextile), well, the main drawback is the impossibility of maintenance during operation.
  3. Closed .Dewatering occurs through pipes laid in a layer of rubble, which is poured into the pits to the depth of two meters.This method is the most common, without the drawbacks of previous versions.It we look at.

Drainage hands - take the job

To make the drainage around the house with his own hands, we need the following tools: shovel, wheelbarrow, hacksaw, spirit level, hand tamper.

drainage device around the house with his own hands begins with digging ditches encircling the foundation, moreover they should be 10-20 cm below its depth and width of about half a meter.Angles for correct pipe laying should be rounded.

More from this trench digging a ditch towards the lowest point of the site where unearth the pit and set plastic drain well.The slope of the base of the ditch should be reduced by at least 10 mm to 1 meter in the direction of the lowest point for drainage by gravity.

then pour in the bottom of the trench 5 cm of sand, do not forget about the slope and carefully compacted.We spread out along the entire length of the ditch at the bottom and the walls of the geotextile in the joints that make an overlap of 15-20 cm.

next step pour it on gravel 10 cm thick, again, do not forget about the slope, and lightly tamped it, and thenit should be laid on a perforated tube, if necessary, at the junction of its reinforcing strap.The two opposite corners of the house set the manholes, in which by means of fittings butted tubes, then we need them to determine the level of water and to remove the blockage.

Then fall asleep pipe rubble from the calculation that the total of its layer is about 40 cm and wrap it our geotextiles, fully closing the rubble from the ground and prevent it from silting.On top of it in this way laid the pipe livnёvoy sanitation.It is made of non-perforated, and the water comes from the pipe livnёvki dock.

Then both tubes are held to the lowest point and are joined to the drainage wells, from which in turn derive the drain pipe in the ditch.Then fill up the trench with soil up to ground level and cover all pre neatly cut off the turf.With this guide, now you know the answer to the question of how to make the drainage of the house.
