Project: Construction Materials Store (floors of the warehouse and sales areas)
Location: Ryazan region
Year: 2015
Duration: 3 days
Technology: SLAB LIFTING
Stabilization of floors after the foundation of a building materials store sinks
Problem
Floors sagged inside the warehouse
Solution
Restoration of the design floor levels
Problem
Task to be solved:
Levelling a section of settled floor surface in a building materials store with a total area of 125 m², strengthening and stabilising uneven soil settlement beneath them without excavation or stopping operations.
Initial data:
In a heated warehouse of a store, during the installation of utility networks inside the warehouse, the floors settled. These deformations were caused by systematic wetting and increased compressibility of the underlying soils due to leaks from nearby water supply pipes. Using geodetic levelling of the floor surface, level differences of up to 26 mm with gaping cracks were identified, and when the floor was opened, voids between it and the soil of up to 40 mm were found. The results of dynamic probing indicated significant soil loosening.
Goal:
Restore the design levels of the floors and shelving in the warehouse premises to ensure normal operating conditions in the shortest possible time.

The project in detail
Technology applied:
The problem was solved by the SLAB LIFTING method according to URETEK technology by injecting a special expanding polymer composition under the floor slabs through small‑diameter holes drilled in them, which filled the existing voids and strengthened the soil while lifting the settled floor sections to the design level.

Solution
The quality and effectiveness of the soil strengthening and lifting of settled floor slabs (up to 20 mm) in the warehouse were verified by dynamic probing and geodetic surveying before and after injecting the mixture into the soil. The repair lasted 3 working days. Geotechnical monitoring of the floor level confirmed the quality of the work one year after the completion of the repair and restoration work.
