For a logistics hub of this scale, the floor is more than just a surface, but a key infrastructure element. Any uneven settlement of the concrete slab turns the perfectly functioning automated systems and loading equipment into a risky and costly operation.
Reason for contacting: “Waves” on a concrete ocean
The owner of a logistics center faced a systemic problem: uneven floor settlement across the entire facility. This resulted in:
- Malfunction of high-rack storage (deviation of racks from the vertical);
- Increased wear of wheels and chassis of warehouse equipment;
- Reduced cargo handling speed due to vibrations and level changes.
Technical Survey: The Treachery of Heterogeneous Soils
A technical inspection of an area of almost 4,500 square meters confirmed that the root of the problem lies inheterogeneity of foundation soils.
- Zones with different load-bearing capacities were formed under the concrete slab.
- In areas of the weakest soil, the slab suffered damage due to voids forming beneath it. Without direct slab-to-soil contact, the concrete structure began to experience extreme bending stress, inevitably leading to failure.
Technical Solution: High-Precision Floor Lifting
Restoring the floor geometry on such a huge area, traditional methods (dismantling and re-pouring) would have meant shutting down business for several months and incurring colossal losses. The solutionGeoresin allowed the work to be carried out with “surgical” precision.
Methodology for performing work:
- Injection of geopolymer composition was carried out to a depth0.5 mfrom the bottom edge of the slab. This made it possible to create a consolidated “cushion”—a geopolymer-reinforced soil mass—under the entire floor.
- By expanding, the GeoResin material instantly filled all hidden cavities and voids, ensuring 100% load transfer from the slab to the ground.
- Thanks to the controlled expansion of the composition, the subsided sections of the slab were smoothly returned to the design plane.
Why was this solution optimal?
Work on the square4495 sq. mrequires flawless process organization. Floor Lifting technology provides advantages unavailable to traditional renovation methods:
- Business Continuity:The logistics center and administrative building continued operating. We did not need to clear the warehouse of shelves or evict the administrative building staff.
- Speed and mobility:The injection equipment moved around the facility without interfering with the movement of other equipment.
- Millimeter accuracy:The lift was controlled by laser levels in real time. This allowed the floor in axes A-H/1-14 to be leveled to the standards required for high-rise stacker operation.
- Purity:No dust, concrete chips, or construction debris. The injection holes are so small that once sealed, they are virtually invisible against the overall industrial floor.
Result of the project implementation
As a result of comprehensive work in the logistics center:
- 4495 sq.m of foundation stabilized. The soil under the slab became homogeneous and resistant to static and dynamic loads.
- The floor slab is leveled and contact with the base is restored over the entire area.
- GeoResin geopolymer does not shrink over time and is not affected by moisture, which eliminates the risk of repeated subsidence.
This case proves that even on large surfaces, industrial flooring can be restored without disrupting operations. We transformed a problematic warehouse into a stable site ready for any logistical challenges.
