Topic: Difficulties of building

If to build something on a permafrost either on bogs or through the rivers - continuous engineering problems. Whether it is possible to tell, what since any depth all these problems leave and there only solid breeds? Well, that once and for ever tunnels to do.

On the average in the north it is depth to 800 meters, sometimes reaches 1000 meters, and peak depths in individual places of 1200-1300 meters. It is a lot of  delivers at drilling of the slits, therefore the first kilometer try to drill very quickly and to surround (on simple speaking to cement).
