The main purpose of the drainage is to drain precipitation and groundwater into a specialized well or ditch. With its help, you can protect the underground part of the building from excess moisture. Corrugated drainage pipe is ideal for the device. It has openings for receiving water inside over the entire surface.
Operational advantages
For laying, double-walled elements are usually used. They are able to withstand the loads exerted by the soil. Perforation is located at the junction of the outer and inner layers. Products can be supplied with a geofilter, which is designed to protect holes from overlapping ground.
Regardless of the material used for production, corrugated drainage pipes have the following advantages:
- operational period up to 50 years;
- convenience in transportation and installation;
- the possibility of laying in trenches with a bend without additional joints;
- the presence of a variety of shaped parts;
- resistance to mechanical influences;
- affordable cost.
Design features allow you to create complex communication systems that take into account the specifics of the area. The project can be easily adjusted during installation work in case of unforeseen circumstances, taking into account the relief pattern.
Polyethylene Products
PND became the most popular polymer material. This abbreviation translates as low-pressure polyethylene. Corrugated drainage pipes made of this material have special stiffeners necessary to withstand the load transmitted by the soil. To reduce costs, the inner wall is usually made of the same polyethylene, but low pressure.
Products can be operated at temperature conditions from -40 to +90 degrees. As a rule, the outer wall is green. The inner surface of the elements is usually black. However, in agreement with the consumer, the product walls are easily painted in other colors.
The cross section of corrugated drainage pipes can be different.

Polyvinyl Chloride Products
Actively used for the installation of drainage systems and corrugated PVC drainage pipes. For placement in the soil, multilayer products marked SN4 or SN6 must be used. Depending on the depth of the conductive elements, the number after the letter can change up or down.
Most often, for individual drainage systems, elements are used, the sizes of which are presented in the table.

Protective shell
So that the holes made do not become clogged after falling asleep with earth, a special layer should be used. Many manufacturers supply the market with corrugated drainage pipes already with it. The most popular are two containment options.
- Geotextile is a water-permeable fabric obtained most often from polypropylene or polyester fibers. In the manufacture of threads are sewn through serrated needles or fastened under the influence of heat.
- Coconut fiber is collected directly from the surface of palm nuts and processed in a special way. The finished material has a porous structure and can withstand significant loads. It features high throughput with minimal exposure to pollution.
Styling recommendations
In most cases, a corrugated drain pipe of 110 mm is selected for work. This section allows you to quite effectively remove moisture from the territory of a suburban area. The diameter of the elements can be increased or decreased depending on the level of groundwater and the amount of precipitation.
For pipes, trenches of the required depth are breaking out. Their minimum width should be three diameters or more. For example, if you intend to use a corrugated drainage pipe of 110 mm, you should dig a ditch with a width of at least 33 cm. Spreading from gravel is carried out in order to protect products from damage and ensure unhindered water penetration.
When laying, the following points should be observed.
- Compliance with a slope of 2 mm per meter is a prerequisite. An increase in this indicator can lead to the appearance of gaps around the pipelines.
- The distance between elements located parallel to each other on clay soils should not exceed 10 m. On other soils, it can be increased to 20-50 m. Decreasing it increases the rate of drainage of the site.
- Depth of laying is determined by the type of soil. However, in any case, it should not be less than 30-60 cm.
- The diameter is selected taking into account the area of the drained territory. For most suburban areas, pipes with a section of 110 and 160 mm are suitable. Pipes with a smaller or larger diameter are laid quite rarely.
High stiffness indicators of PVC and HDPE products allow laying directly under highways. The maximum laying depth can reach 6 m, subject to the basic requirements and the correct selection of diameter.
