Commercial Projects

We perform injection works on commercial and industrial facilities of various purposes — from retail and public buildings to warehouses, logistics, and production complexes. Soil injection technologies, base stabilization, lifting of concrete structures, and excavation pit protection allow us to effectively work with facilities at any stage of construction or operation.

Our solutions are used to eliminate settlement, deformations, and risks of loss of load-bearing capacity, as well as to reinforce excavation walls in complex soil conditions. Inject operates under high loads, limited access, and active infrastructure, ensuring predictable results and long-term structural stability without stopping facility operation.

Operating fuel station complex

Restoration and strengthening of the base of a concrete slab and the foundation of a fuel dispenser at an operating fuel station complex

During the inspection of the roadway and the foundation of the fuel dispenser, local settlement of the concrete slab, the presence of voids beneath it, and loss of contact with the soil base were identified. Additionally, soil loosening was recorded in the foundation area of the dispenser, caused by prolonged transport loads, vibrations, and washout of fine soil particles, creating risks of further pavement deformation and reduced structural stability.

To restore full slab–soil contact, eliminate voids, increase the load-bearing capacity of the soil, and stabilize the foundation of the fuel dispenser without dismantling structures and without interrupting the operation of the fuel station, injection strengthening with a gel composite solution in two levels was applied.

Completed works:

During the execution of works, geodetic marking of drilling points was carried out in accordance with the design scheme, Ø45 mm boreholes were installed through the concrete slab and in the area of the fuel dispenser foundation, followed by staged injection of the gel composite solution at two levels with control of pressure and material consumption.

In the upper zone (−0.3…−1.2 m), injection was performed to fill voids under the concrete slab and restore slab–soil contact, while at depths up to −6.0 m, borehole injection compaction of loosened soil layers was carried out under pressure up to 8.0 MPa, ensuring the formation of a spatially compacted soil mass beneath the structures.

As a result, voids under the slab were eliminated, slab–soil contact was restored, deep compaction of weakened soil layers was achieved, and technological openings were sealed with restoration of the surface. The works were performed under continuous operation of the facility.

METRO shopping center

Lifting and stabilization of a sunken industrial floor 

During the technical inspection and geodetic survey at the shopping center, local and extended zones of settlement of the reinforced concrete floor slab were identified, with deviations reaching −50–60 mm from the design levels.

The investigation determined that the causes of deformation were unevenly compacted soil base during construction, as well as leaks from underground utilities during operation, which led to soil washout, additional compaction, and the formation of sub-slab voids with depths of 100–200 mm. The identified condition created a risk of loss of load-bearing capacity of the floor slab and further development of floor deformations, causing operational inconvenience.

Completed works:

To restore structural stability, deep injection of a gel composite solution was carried out to a depth of −2.0 m from the floor surface, according to a specially designed volumetric planning scheme.

To return the reinforced concrete floor to the design level and eliminate voids, gel composite injection was performed under pressure up to 8 MPa at a depth of −0.5 m from the floor surface.

All works were carried out without dismantling the existing floor covering and without interrupting the operation of the shopping center.

The total area of stabilization and restoration of the industrial floor level using the injection method amounted to 4,500 m².

Fuel station

Restoration of the load-bearing capacity of the roadway slab and fuel dispenser foundations

During the operation of the fuel station, uneven settlement of fuel dispenser foundations and local deformations of the reinforced concrete roadway slab were recorded. Engineering investigations revealed the presence of voids beneath the slab up to 500 mm deep, formed as a result of soil washout due to damaged underground utilities and dynamic loads from traffic. The load-bearing capacity of the soil in the affected area was 0.7–1.0 kg/cm², which was insufficient to ensure stable performance of the structures.

To prevent further development of deformations, a decision was made to perform injection strengthening of the base with simultaneous filling of voids under the slab without interrupting the operation of the fuel station.

Completed works:

Geodetic marking of drilling points was carried out taking into account the location of underground utilities, and 47 injection boreholes Ø45 mm with a depth of up to 5.0 m were drilled. Staged injection of a gel composite solution was performed under controlled pressure up to 8 MPa, with monitoring of consumption and injection volumes at each borehole.

During the works, layer-by-layer filling of voids beneath the slab, compaction of loosened soil layers, and stabilization of fuel dispenser foundations were ensured. Throughout the injection process, geodetic and visual monitoring of slab position was carried out. After completion, packers were removed, and technological openings were sealed.

Grocery and non-food store

Gel composite stabilization of the soil base and lifting of the reinforced concrete floor slab to the design level

During the construction phase of the store, visual inspection revealed local settlement from the design level and the formation of cracks in the concrete floor slab.

Geodetic surveys identified unevenly compacted soil and a water-saturated base zone beneath the slab down to −4.0 m, which led to loss of load-bearing capacity and uneven slab deformation up to −65 mm from the design level.

This technical condition created hazardous operating conditions for the retail space.

Completed works:

To ensure stable operation, a technical solution was adopted with localized impact on the cause of deformations — specialized gel composite soil stabilization within the defined zone beneath the slab, without dismantling structures and without affecting the load-bearing elements of the building.

To fill voids and strengthen the base beneath the floor slab, gel composite injection was carried out to a depth of up to −4.0 m from the zero design floor level under pressure up to 8 MPa.

The total area of stabilization and restoration of the floor to the design level using the injection method amounted to 350 m².

Production and warehouse facilities of Umanpivo

Comprehensive strengthening of the foundation base of production buildings

During technical monitoring of the buildings, uneven settlement of foundations was identified in areas with heavy brewing equipment, along with the appearance of cracks in load-bearing walls and floor slabs, local reduction in soil density, and uneven floors in warehouse areas.

The main causes were determined to be long-term operation of the buildings, significant static and vibration loads from technological equipment, periodic soil moisture, and seasonal temperature fluctuations. To prevent further development of deformations and stabilize the structures, it was decided to perform injection strengthening of the soil base of foundations without stopping the production process.

Completed works:

To stabilize the foundation base, borehole injection technology by Inject was applied using injection solutions that ensure soil compaction and structural reinforcement of the soil mass. As part of the works, geodetic marking of strengthening zones and drilling of Ø45 mm boreholes up to 8.0 m deep were carried out in a staggered pattern in the most loaded areas of foundations and floor slabs.

Through the boreholes, staged injection of the solution under controlled pressure up to 8.0 MPa was performed, ensuring elimination of voids, compaction of loosened soil layers, and formation of overlapping reinforcement zones beneath the foundations.

After completion of the injection works, technological openings were sealed, a control geodetic survey was carried out, and all works were performed without dismantling equipment and without stopping production.

Retail premises

Injection works to eliminate moisture in basement walls

During rainy conditions, a visual inspection of the basement level revealed local areas of wall moisture penetration. The moisture appeared as wet spots on the masonry surface, darkening of the finishing layer, and increased moisture content of wall materials in the lower part of the premises. The affected zones had clear localization and were concentrated near structural joints and areas of potential leakage points.

The nature of the defect during rainy periods indicates penetration of atmospheric and groundwater moisture through the enclosing structures due to the capillary-porous structure of materials, as well as through existing microcracks and discontinuities.

Completed works:

To eliminate the causes of wall moisture penetration in the basement, a complex of injection waterproofing measures was carried out.

Gel composite injection was performed into the thickness of the masonry with extension beyond its boundaries to form a waterproof barrier in the adjacent soil mass. The waterproofing composition was injected under controlled pressure up to 8 MPa in areas of intensive moisture penetration.

After completion of the injection works, packers were removed, and the integrity of the masonry was restored by filling the holes with a specialized repair compound.

Educational Complex No. 209 “Suzirya”

Protection of the excavation pit against collapse and ensuring safe construction of a dual-purpose facility (radiation shelter)

During earthworks for the construction of an excavation pit with a depth exceeding −6.0 m, it became necessary to ensure its stability under conditions of sandy and sandy loam soils and dense urban development. The immediate proximity of an existing educational building and the significant excavation depth created increased risks of pit wall collapse, local soil slides, and possible deformations of adjacent structures.

To prevent these risks, a decision was made to perform injection soil stabilization along the perimeter of the excavation pit with the formation of a spatial protective soil mass acting as an injection-based retaining system.

Completed works:

To stabilize the pit walls, borehole injection technology by Inject was applied using a cement-silicate solution injected under pressure up to 8.0 MPa. As part of the works, geodetic marking of drilling points was carried out, followed by drilling 909 boreholes with a diameter of 45 mm to a depth of up to −8.0 m along the perimeter of the excavation pit.

Through the boreholes, controlled injection of calculated solution volumes was performed with monitoring of material consumption at each point. This ensured soil mass compaction and the formation of overlapping injection zones, creating a continuous reinforced contour that protects the excavation pit from collapse.

Secondary General Education School No. 158 (Grades I–III)

Strengthening of the foundation base of shelters and engineering preparation of the building for further arrangement of a civil protection facility (bomb shelter)

During the technical inspection of the basement premises of the school, intended for further conversion into a civil protection shelter, local settlement of the soil base of foundations, cracks in walls and partitions, and a decrease in soil density beneath certain foundation areas were identified.

The detected defects were caused by changes in hydrogeological conditions, the influence of groundwater, and natural soil settlement processes, creating risks of further structural deformations, local soil slides, and soil collapse in the foundation zone during operation and construction works.

To ensure safe operation of the building and create the necessary engineering conditions for the arrangement of a bomb shelter, a decision was made to perform injection strengthening of the soil base of foundations.

Completed works:

Preschool Educational Institution No. 395

Installation of a waterproofing barrier and partial base strengthening 

The basis for the engineering and technical inspection was the recorded cases of groundwater penetration into the basement premises, where a civil protection shelter is located. This required an assessment of the condition of the soil base of foundations and the existing waterproofing system.

The inspection revealed increased soil moisture in the foundation zone, signs of capillary moisture penetration into building structures, local areas of soil loosening, and risks of further deformation development. The main causes were identified as a high groundwater level, partial loss of effectiveness of the existing waterproofing layer, and malfunction of the drainage system.

To prevent further moisture penetration and stabilize the soil base, a decision was made to perform injection installation of a waterproofing barrier combined with local foundation base strengthening.

Inclusive Resource Center

Strengthening of the soil base of foundations and prevention of excavation wall collapse

During the technical inspection of the building, manifestations of uneven foundation performance were identified, expressed in cracks in foundation structures, cracks in load-bearing walls, and damage to the integrity of the blind area. The analysis of causes showed that the upper layers of the soil base had lost density due to natural settlement and washing out of fine particles, which led to a decrease in their bearing capacity.

As part of the reconstruction, the construction of an excavation for a shelter extension near the existing foundations was planned. Given the current soil condition, earthworks could have caused excavation wall collapse and additional deformation of the building. This determined the need for preliminary engineering stabilization of the soil mass by deep injection using Inject technology. Solving such engineering challenges is a core specialization of our company.

Completed works:

The works were carried out in accordance with the design scheme in two stages by installing bored injection holes Ø 45 mm with a depth of up to 4 m.
