Drainage tunnel
For the construction of cottages, the ideal option would be to use drainage tunnels. Here you can take one or more modules, and during installation the first and last element are mounted on the side where there is a plug and timely made holes for outlet pipes, whose diameter is 110/160/200/250 mm. The installation is quite easy to cope with, since the entire structure is laid on the same level, and each element has a relatively small weight (10 kg).
The drainage tunnel has a fairly high storage capacity – 95%, which is three times higher than that of a gravel system. It turns out that one element of the drainage tunnel replaces about eight hundred kilograms of gravel or 36 meters of drainage pipe.
In addition, drainage systems are capable of natural filtration of water through the soil, which is especially important for places located near large industrial facilities.

It is difficult to find an alternative to drainage – it is used in road construction, the construction of high-rise buildings and low-rise buildings. In addition, it is often used during landscaping work and in agriculture in general.
