Project: Cinema (Shopping and Entertainment Complexes)
Location: Smolensk region
Year: 2020
Duration: 2 days
Technology: DEEP INJECTION
Strengthening the foundation and stopping the sinking of the supporting columns inside the building
Problem
The internal load-bearing columns have settled
Solution
Stopping uneven precipitation of column foundations
Problem
During the operation of the building, the internal load‑bearing columns underwent settlement. The cause was uneven compaction of the foundation soils (backfill soils).
Task
Strengthen the foundation soils, stop uneven settlement of the column foundations.
Method
Uretek Deep injection.
Task
Strengthen the foundation soils, stop uneven settlement of the column foundations.
Method
Uretek Deep injection.
Solution
Before starting the foundation strengthening work, a series of geodetic surveys was carried out to accurately determine the position of the columns in space (in the vertical and horizontal planes). Loosened horizons of the foundation soil were also identified using dynamic probing. A separate study made it possible to detect local zones of voids under the floor slab. To solve the task, the deep injection method – Uretek Deep Injection – was chosen. All work was carried out from the surface of the first‑floor slab, with injections performed at calculated angles using the "wave principle". Void filling was performed strictly vertically. All work was carried out under constant supervision of the surveying service.
