How to equip wall drainage for a private house

Without wall drainage, any private house is at risk of flooding, so it is necessary in the process construction and commissioning of the building to think about the quality arrangement of the drainage system basement. Wall drainage will protect the house from groundwater and heavy rainfall, as well as significantly increase the life of the building.

Preparation for construction

You can build a drainage around the perimeter of the house with your own hands. To do this, prepare the necessary tools:

• Shovel;
• Level;
• The cart for export of the dug up soil and transportation of building materials;
• Hacksaw for cutting iron rods.

Before starting work, the builder should find out a number of nuances that affect the course of further construction of the drainage. Firstly, it is necessary to determine what depth will be in the system that removes water from the foundation. It cannot be less than the maximum depth at which the soil freezes in the winter season. Secondly, you need to think about what will be the drainage slope. Water should flow through the system at a speed of about 1 m / s. Measurements should be carried out in an already open ditch, but not yet covered with drainage. It is also necessary to consider where the groundwater that is unnecessary in the area near the house will flow. Typically, the slope of the drainage system is directed towards the lake or river, and in the absence thereof, towards the ravines or large slopes.

Getting to work

First you need to dig trenches around the house. The width of the trench should be slightly wider than the diameter of the drainage pipe. The depth of the trench should be several tens of centimeters deeper than the depth of the foundation of the building.
When digging a trench, builders should constantly measure the angle of inclination in order to avoid flooding of the house in the process of arranging wall drainage.

After the ditches are completely dug up, sand must be poured onto their bottom. The layer should be at least 10-20 cm. After that, it is necessary to lay geotextiles on the sand, on top of which a thirty-meter layer of gravel or other similar building material is poured. Then the trench must be carefully rammed. Usually, heavy loads are used for this, for example, bags of cement or sand.

After the soil is compacted into the trench, it is necessary to lay drainage pipes interconnected by fasteners that impede the flow of water. At the corner joints, it is necessary to put manholes. To them it is necessary to attach the branches from the storm water inlets so that the water from the roof does not flow to the site during a shower, but falls directly into the wall drainage system.

After the pipes are laid and connected, they need to be led out towards the lake or a cliff, and then they should be covered with gravel about halfway. After this, you need to lay on top another layer of geotextile that protects the body of the drainpipes from contact with the ground.

The system is ready for use, it remains only to fill the ditch with sand about 15 cm, and then compact it. The rest of the pit should be covered with excavated soil at the initial stage of construction. In order not to spoil the appearance of the adjoining area on top of the trench, lay a layer of turf.
