Deep drainage

Everyone knows about the destructive power of water, and many firsthand. When moisture affects the material for a long time, even basalt is extremely difficult to resist, and it is considered only the most strong natural formations. Talking about brick and concrete, which differ in a much lower level of strength, do not have to.

You can expand the operational resource of such building materials only by minimizing their relationship with water. In this case, if not unique, then the most effective solution to this problem will be drainage at home.

To arrange drainage around the house, as a rule, polymer pipes are used, which differ significantly from traditional water or sewer. Firstly, such pipes are equipped with special holes through which water seeps inside them. Secondly, the technological design of these pipes implies protection against complete siltation above the mentioned holes, since water turns the soil into a slurry.

In the cold season, a problem with ice on the roads appears. So that the ice does not become a headache for you, we advise you to purchase anti -icing agents. They are of different types and type. Go to the above link and you will find detailed information about which means to use, methods of their use and a lot of useful tips.

Additional protection against siltation is ensured by the method of installing drainage systems. Given the type of foundation, a trench is born, the depth of which is from 0.8 to 3.5 m, and the width of the base 50 cm. A layer of gravel (about 10 cm), granularity no more than 20 mm must be poured to the bottom. This “pillow” will be the foundation for the installation of a drainage pipe. All the resulting design is covered with crushed stone on top, it is necessary to pour sand to the remaining height. To divide crushed stone and sand in drainage systems, as a rule, experts use a geotextile filter.

The diameter of the pipes directly depends on the purpose. If the drainage calling is the protection of the foundation, then throughout the perimeter you need to lay pipes with a dimeter11 cm. If you need to protect the site or garden, the diameter of the pipes should be at least 0.8 m.

Usually, in tandem with deep drainage, a livery is also performed. With the aim of some savings on excavation, it is laid in that trench as the drainage system.
