Project: Private country house
Location: Kaluga
Year: 2017
Duration: 1 day
Technology: DEEP INJECTION
Strengthening the foundation and raising the sunk foundation
Problem
A sagging corner of the house and a crack in the foundation
Solution
Stabilization of deformations
Problem
Task to be solved:
Strengthen the foundation soils and lift settled structures in the shortest possible time.
Initial data
The owners of a summer house were concerned about a settled corner, including a crack in the body of the FBS block foundation. A visual inspection revealed that the corner had settled due to high compressibility of the foundation soil when wetted and a reduction in bearing capacity, which caused cracks between the blocks.
Objective
Restore the operational qualities of the residential house and stabilise deformations.
Strengthen the foundation soils and lift settled structures in the shortest possible time.

The project in detail
Technologies applied:
The solution to the problem was facilitated by the DEEP INJECTION method according to URETEK technology, which involved injecting an expanding polymer mixture into the foundation soil to strengthen it and lift the settled foundation at the corner of the house. In total, 8 injections were performed at different levels under the foundation footing, which ensured strengthening of the foundation soil and lifting of the settled structures by an average of up to 5 mm, with the net work time (injection) taking only 4 hours.

Solution
The effectiveness of the measures taken was expressed in the restoration of normal operating conditions for the residential house. The quality of soil strengthening was verified by probing tests before and after strengthening, and the lift of the structures was verified by laser monitoring.
