A breakthrough occurred during the construction of the metrotram in Krasnoyarsk - technical fluid reached the surface near the intersection of Gorky and Karl Marx, near the future station at Revolution Square, the manager of the construction of the metrotram explained that "bentonite came out" at the site. In tunnel construction it is used to prepare drilling fluids. They also added that they knew about the incident in advance, since it happens when the work is carried out at a shallow depth (in the Revolution Square, the depth of the station is 16 meters) and in technogenic soil (that is, not natural rock, but in a cultivated layer of "soil"). With the removal of the mixture from the road, the road there will be compacted and the crossing will be opened, the administration added.
