FIELD: construction.
SUBSTANCE: method of underpinning of subfoundations erected on the weak water-saturated ground and in a space-limited environment involves charging of a quick-setting cement mortar into the pipes installed in the holes drilled through the foundation support and the ground. The pipes are manufactured of flexible plastic with closed bottom ends, and the middle part of these pipes is equipped with steel pipes located between the foundation base and the layers of the ground with enhanced bearing capability.
EFFECT: underpinning of foundations.
