Project: Logistics complex
Location: Moscow Region, Russia
Year: 2025
Duration: 7 days
Technology: DEEP INJECTION & SLAB LIFTING
The floors were going down — the engineers had lifted the slab without heavy equipment
Problem
Uneven floor subsidence has become critical for the warehouse's operation
Solution
Stabilization of the foundation and leveling of sagging floors under load
Problem
Spring 2025. The owners of a large warehouse building faced an alarming signal: concrete floors began to noticeably sink in different zones of the complex. The facility itself had existed for almost a decade, and the first minor deformations were perceived as inevitable “natural settlement”. But time put everything in its place – uneven settlement became critical. The threat to personnel safety and cargo integrity turned from potential to real. At this point, engineers got involved. Their task was not just to stabilise the floors, but to restore the customer’s confidence in the operational reliability of the building.
The project in detail
Diagnostics: a look into the depth
The first stage was detailed exploration. A visual inspection revealed multiple signs of deformations, but the picture was incomplete. The engineers went further: a set of geotechnical investigations was launched using dynamic probing. The goal was to understand exactly where voids had formed under the slab and which layers of the foundation had lost density. For this purpose, probing points were placed according to a pre‑prepared engineering plan, covering the entire floor area. This approach made it possible to see the real structure of the underground mass – not abstract indicators, but precise values of density and bearing capacity at different depths.
The results confirmed the assumption: loosened zones had formed in the foundation. These hidden areas acted as “soft spots” – exactly where the load from the reinforced concrete slab fell, causing uneven settlement.

Solution
Development of the solution: from data to technology
Once the soil picture was revealed, it became clear that classic methods such as additional surcharging or mechanical compaction would not work here. A technology was needed that could work pointwise, at depth, and without stopping warehouse operations. The choice fell on deep injection of Uretek polymer material. This solution was not accidental: the material, injected under pressure, penetrates the loosened zones, fills voids, contacts soil particles and, expanding, forms monolithic inclusions. As a result, the weak mass turns into a strengthened structure, ready to once again bear the foundation load. This solution meets the principles of modern engineering: minimal intervention, maximum efficiency, long‑term stability.
Implementation: engineering without stopping processes
After the project was agreed, specialists went to the site. The key task was to stabilise the floor slab and return it to the design level. The work was carried out without heavy equipment, without noise and dust, without stopping warehouse operations. The injection units were compact, mobile and allowed work directly in storage areas. Employees continued to perform their duties, cargo flows were not interrupted. For the customer, this was a critical factor: the warehouse not only did not lose productivity, but also continued to generate profit during the engineering intervention. Injections were carried out layer by layer, with constant monitoring of pressure and structural lift. Surveyors recorded every change in real time. This process can be compared to precision surgery: the intervention is invisible from the outside, but profound transformations occur inside the system.
Project completion and subsequent monitoring
When the injection work was completed, the facility underwent a final geodetic survey. The floor slab returned to its design position, deformations were eliminated. The foundation acquired new strength, and the risk of further settlement was removed. The customer received a package of operational recommendations and a scheme for further geomonitoring. Specialists scheduled regular control measurements to eliminate the possibility of recurring problems.
Conclusion: a high level of engineering
The story of this warehouse clearly shows that modern engineering is no longer limited to crude repairs. It is already a high‑tech field using new‑generation materials, and interventions resemble a precision operation. The method of deep polymer injection has become not just a solution to a local problem. It turned a potentially emergency facility into a reliable and safe complex, preserving its operation in real time. This is how Uretek engineering works: without stops, without excessive costs, with full control over processes and a durable result.
