The main purpose of drainage is to drain precipitation and groundwater into a specialized well or ditch. With it, you can protect the underground part of the building from an excess of moisture. A corrugated drainage pipe is ideal for the device. It has holes for receiving water inside over the entire surface.

Operational benefits

Double-walled elements are usually used for laying. 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 the holes from being blocked by earth.

Regardless of the material used for production, corrugated drainage pipes have the following advantages:

• operational period up to 50 years;
• ease of transportation and installation;
• possibility of laying in trenches with a bend without additional joints;
• the presence of a variety of shapeddetails;
• resistance to mechanical stress;
• 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, while taking into account the relief pattern.

Polyethylene products

HDPE has become the most popular polymer material. This abbreviation translates as low pressure polyethylene. Corrugated drainage pipes made from this material have special stiffening ribs 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 temperatures 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 walls of the products can be easily painted in other colors.

Section of corrugated drainage pipes may vary.

Diameter in millimeters
Internal	External
172	200
137	160
107	125
94	110
77	90

PVC products

Actively used for drainage systems and PVC corrugated drainage pipes. For placement in the ground, multilayer products marked SN4 or SN6 should be used. Depending on the depth of the conductive elements, the number after the letter may change up or down.

Most often, for individual drainage systems, elements are used, the dimensions of which are presented in the table.

Section in millimeters	Volume in cubic meters
110	1, 75
90	1
63	0, 7

Protective shell

So that the holes made do not become clogged after falling asleep with earth, a special layer must be used. Many manufacturers supply corrugated drainage pipes to the market already with it. The two most popular protective shell options.

1. Geotextile is a permeable fabric, most often obtained from polypropylene or polyester fibers. The threads are sewn through with serrated needles or heat-sealed.
2. Coconut fiber is harvested directly from the surface of palm nuts and processed in a special way. The finished material hasporous structure and can carry significant loads. Features increased throughput with minimal exposure to contamination.

Installation tips

In most cases, corrugated drainage pipe 110 mm is selected for work. This section allows you to 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 dug. Their minimum width should be three diameters or more. For example, if a 110 mm corrugated drain pipe is to be used, a ditch of at least 33 cm wide should be dug.

When laying, the following points should be observed.

1. Compliance with a slope of 2 mm per meter is a must. An increase in this indicator can lead to the appearance of gullies around pipelines.
2. 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. Reducing it increases the rate of drainage of the site.
3. The depth of laying is determined by the type of soil. However, in any case, it should not be less than 30-60 cm.
4. The diameter is selected taking into account the area of the drained territory. For mostsuburban areas suitable pipes with a cross section of 110 and 160 mm. Pipes with a smaller or larger diameter are rarely laid.

The high rigidity of PVC and HDPE products allows laying directly under roads. The maximum laying depth can reach 6 m, subject to the basic requirements and the correct selection of the diameter.

Final part

In areas with difficult terrain, corrugated drainage pipes can be the best solution. They make it possible to bypass all sorts of bends encountered on the way. When they are used, the time of work is significantly reduced, especially when it comes to engineering systems that are complex.
