Project: Private residential building (annex to the building)
Location: Moscow region
Year: 2020
Duration: 2 working dayы
Technology: DEEP INJECTION
Reinforcement of the foundations in the area where the residential annex is attached to the building
Problem
Elimination of subsidence of foundations
Solution
Reinforcement or stabilization of the base soils
Object:
3-storey residential building with a basement floor, total area 600 m². The foundation is a monolithic strip foundation with a depth ranging from -1.8 m to -2.2 m.
3-storey residential building with a basement floor, total area 600 m². The foundation is a monolithic strip foundation with a depth ranging from -1.8 m to -2.2 m.
Problem
During a visual inspection, through vertical cracks were found at the junction of the additionally erected wall structures of the building, as well as opening of the joints of the precast floor slabs. The nature of the crack formation indicated uneven deformation in the foundation base of the part of the building attached to the main volume.
Task:
Partial strengthening of the soils under the extension and capture of the wall at the junction point.
Task:
Partial strengthening of the soils under the extension and capture of the wall at the junction point.
Solution
Strengthening of the foundation soils was carried out in two levels to depths of 2.9 m and 2.3 m directly under the footing of the strip foundation. The work area was under constant real‑time control using a laser level during the filling of voids in the foundation base.
