LLC WINNER AUTOMOTIVE

In this project, Georesin specialists solved the problem of restoring the foundation’s load-bearing capacity without dismantling structures or interrupting business processes.

Symptoms and engineering audit

The customer contacted us during the active deformation phase. A visual inspection revealed:

• Vertical and inclined cracks on load-bearing walls are a clear sign of uneven foundation settlement.
• Subsidence of the concrete floor caused equipment to become distorted and disrupted logistical routes within the building.

Technical analysis revealed a complex problem:

• Hydrogeological factor:Long-term soil waterlogging resulted in the loss of the calculated soil deformation modulus.
• Structural defects of the foundation:Voids (“lenses”) formed under the concrete slab due to the erosion of fine soil particles and the natural shrinkage of the uncompacted base.
• Heterogeneity:The soils under the foundation had different densities, which caused subsidence.

Renovation methods used

To solve the problem, a combined injection strategy of Georesin geopolymer resins was chosen, which allows for precise and “surgical” work.

Deep Lifting Method

It was used to stabilize the foundation.Expanding under high pressure, the material fills the soil’s micropores, displaces moisture, and instantly compacts the soil. This creates a rigid “cushion” that absorbs the load from the building’s walls and columns.

Floor Lifting Method (Leveling Slabs)

Used to restore the geometry of the floor.The composition is introduced directly under the concrete slab, filling the cavities and restoring 100% slab-to-soil contact.The expansion force of the geopolymer allows the slab to be smoothly raised to the design marks, leveling the floor plane.

Benefits of project implementation

Working in a non-stop production environment is always a challenge. Georesin technologies provide a number of critical advantages:

1. Zero Downtime Principle:All work was carried outwithout stopping business processesAll employees continued to perform their tasks.
2. Strength gain rate:Geopolymer reaches 90% of the calculated strength after only15 minutesafter insertion. This allows the floor to immediately bear the calculated operational load.
3. Geodetic control:To ensure perfect accuracy, real-time monitoring was conducted using laser levels and high-precision sensors. Any movement of the structure was tracked with high precision..
4. Cleanliness and eco-friendliness:No excavation work, concrete dust or dirt.

The result of the work performed

As a result of engineering intervention, complete stabilization of the object was achieved:

• The cracks have stopped opening up.on the walls of the building.
• The floor geometry has been restoredOn a plot of 330 m2, level differences have been eliminated.
• Reinforced foundationunder all types of foundations (strip and columnar).
• Money savedcustomer due to the absence of the need to dismantle the floor and downtime during work.
