Project: A three-storey residential building with underground parking
Location: Kazakhstan, Almaty
Year: 2018
Duration: 5 days
Technology: DEEP INJECTION & SLAB LIFTING
Foundation reinforcement with leveling of the roll of a three-storey building with underground parking
Problem
Progressive uneven foundation settlement with a roll
Solution
Strengthening of the foundation grounds and leveling of the building
Problem
Task to be solved:
Carry out work in the shortest possible time, without excavation.
Initial data
The owner of a country house was concerned about a settled corner and a crack that had developed on the external cladding of the building. A visual inspection revealed that these deformations were the result of high compressibility of the clay soil in the foundation base due to excessive wetting.
Objective
Eliminate the consequences of deformations by strengthening the soil in the foundation base of the residential house, filling micropores.

The project in detail
Technologies applied:
The problem was solved by the DEEP INJECTION method, injecting a polymer composition into the soil under the foundation of the settled corner. Due to expansion, the composition created compaction and consolidation of the weakened soil with partial lifting of the settled structure at the corner of the house, generally providing a moisture‑impermeable foundation.

Solution
The quality of soil strengthening and lifting of the settled corner structure was verified by geodetic survey and dynamic probing before and after injecting the mixture into the soil, as well as by laser monitoring of the vertical lift of the settled structures (average 5 mm) during the project. Upon completion of the last injection, the closing of the cracks with installed markers was visually recorded.
