Residential Projects

We perform injection works at private residential properties — from individual houses and cottages to multi-apartment buildings and extensions. Technologies of soil injection, base stabilization, lifting of concrete structures, and protection of excavations from collapse allow effective elimination of settlements, cracks, and deformations without large-scale dismantling or intervention in building structures.

Our solutions are applied to restore the bearing capacity of foundations, stop further settlement, and strengthen the base in complex soil conditions. Inject operates carefully, with minimal impact on landscaping and interior finishes, ensuring a predictable result and long-term structural stability.

Strengthening of the soil base under two swimming pools and adjacent recreation areas

During the visual inspection, signs of local subsidence of the soil base were recorded in areas adjacent to the swimming pool bowls on both sites.

The following was identified:

• local irregularities of the surface leveling;
• signs of loss of soil density in the near-edge zones of the bowls;
• potential risks of uneven deformation affecting the pool structures and their waterproofing.

There was no pavement in these zones, which made it possible to perform the works without dismantling measures.

Completed works

To increase the bearing capacity of the soil base under the bowls of two swimming pools and in adjacent areas, bored injection gel composite compaction and stabilization of soils were carried out.

Injection depth was up to 3 m and 5 m from the surface of the near-edge zones of the bowls, with pressure up to 8 MPa.

Injection of the solution was performed under geodetic control using a laser level within the regulated lifting limits of the near-edge zones to prevent deformation of the pool structures.

Within the soil mass, overlapping zones of compaction were formed under the pool bowls and within the adjacent planning areas.

Private residential house

Elimination of floor subsidence by controlled injection method

In the premises, uneven floor subsidence of up to –70 mm from the design level was recorded.

During the inspection, local voids beneath the concrete floor with a depth of up to 100 mm were identified, formed as a result of loosening of the soil base.

The identified defects indicated:

• loss of contact between the floor and the base;
• presence of loosened zones and voids;
• risk of further development of deformations and damage to finishes.

Dismantling of tiles, furniture, and floor structures was not acceptable.

Completed works

To restore the design elevations of the floor and stabilize the soil base beneath the concrete slab, the method of controlled injection of a gel composite solution with simultaneous geodetic monitoring of the lifting process was applied.

Within the subsidence zone, a drilling grid was marked and 25 injection boreholes Ø43 mm with a depth of up to –7.0 m were installed — reaching dense soil layers to prevent further deformations. Through the boreholes, stage-by-stage injection of the gel composite solution was carried out under regulated pressure.

During the injection process, the following was ensured:

• filling of voids beneath the concrete floor;
• compaction of loosened zones of the soil base;
• gradual controlled lifting of the structure to the design elevations.

The floor lifting was carried out under continuous geodetic monitoring, which made it possible to accurately track elevation changes and timely stop the injection after reaching the required level.

Private residential house

Strengthening and stabilization of the foundation base of a private house

During the operation of the building, the owner recorded signs of structural deformation — cracks in the walls and local foundation settlement, which became the basis for conducting an engineering inspection and developing strengthening measures for the base.

According to the inspection results, a decrease in soil density beneath individual sections of the foundation and the development of uneven deformations caused by rising groundwater levels, uneven moisture conditions, and natural soil settlement processes were identified.

Further development of deformations could have led to deterioration of the load-bearing structures of the house, which determined the need to perform foundation base stabilization works without dismantling structures and without relocating residents.

Completed works

To strengthen the foundations, the Inject bored injection technology using a gel composite solution was applied. Within the scope of the works, marking of injection zones and drilling of boreholes Ø45 mm with a depth of up to 5.0 m along the perimeter of the building were carried out.

Through the boreholes, layer-by-layer injection of the gel composite solution was performed under regulated pressure, ensuring compaction of loosened soil layers and formation of overlapping injection zones beneath the foundations.

The works were carried out using compact equipment without excavation and without intervention in the interior of the house, with continuous monitoring of the structural condition.

After completion of the injection, the technological openings were sealed, and the territory was restored to operational condition.

Injection strengthening of foundations and stabilization of a load-bearing wall

During the operation of the house, signs of uneven performance of the foundation soil base were identified, manifested by cracks on the facade, local distortions of openings, and subsidence of the blind area.

Additional inspection revealed the need to strengthen the load-bearing wall of the basement to prevent further development of deformations and to ensure uniform load transfer from the above-ground structures.

Completed works

To stabilize the structures, drilling of 118 injection boreholes Ø45 mm with a depth of up to 4.0 m was carried out along the external perimeter of the foundation and within the internal basement zone.

Through the boreholes, stage-by-stage injection of a gel composite solution was performed under controlled pressure, ensuring compaction of loosened soil layers and formation of stabilizing injection masses beneath the foundations.

The works were carried out with continuous geodetic monitoring of the structural condition, without excavation and without disturbing the existing landscaping.

Private residential house

Stabilization of foundations and lifting of the floor of a residential house with a swimming pool

During the operation of the residential building, cracks appeared in the load-bearing walls of the first and second floors, as well as local subsidence of the first-floor slab. Inspection revealed uneven compaction of the soil base beneath the foundations, local zones of over-saturation due to deficiencies in the drainage system, and additional loads from the swimming pool, which led to uneven settlement of the building structures.

Completed works

To stabilize the foundations and restore the floor geometry, the Inject bored injection technology was applied. At the site, 312 injection boreholes Ø45 mm with a depth of up to 5.0 m were drilled, through which stage-by-stage injection of a gel composite solution under regulated pressure was carried out.

During the injection process, compaction of loosened soil layers, filling of voids beneath the foundation base, and stabilization of the structures were ensured. At the same time, controlled lifting of the subsided first-floor slab was performed with restoration of the design elevations.

After completion of the works, the technological openings were sealed and the coating was restored.

Private residential house

Stabilization of the foundation base and floors by injection method

During the operation of the building, local deformations of floor structures and signs of loss of stability of the soil base in certain areas of the house were recorded. Inspection revealed the presence of loosened soil zones and disruption of uniform load transfer from the structures to the base, which created a risk of further settlement and development of deformations in foundations and floors.

Considering the need to perform the works without dismantling structures, a decision was made to apply injection technology for stabilization of the soil base with the formation of a compacted mass beneath the problem areas.

Completed works

Within the site, engineering marking of stabilization zones was carried out and 154 injection boreholes with a depth of 2.0 m were drilled in accordance with the design scheme.

Through the boreholes, stage-by-stage injection of a gel composite solution under regulated pressure was performed, ensuring filling of local voids, compaction of loosened zones of the soil base, and restoration of uniform performance of foundations and floor structures.

Injection was carried out under continuous geodetic monitoring, which made it possible to track possible structural movements in real time and ensure uniform stabilization of the base.

After completion of the injection, the technological openings were sealed and the surfaces at the work locations were restored.

Strengthening of foundation bases and stabilization of floors by injection reinforcement method

At the stage of house construction, cracks in load-bearing walls and local deformations of floor slabs were identified. Inspection revealed uneven compaction of the soil base and formation of loosened zones beneath the foundations, which created a risk of further settlement of structures and widening of cracks.

To promptly eliminate the causes of deformation without dismantling structures, a decision was made to apply injection technology for strengthening the soil base with geodetic monitoring of the stabilization process.

Completed works:

Within the project, marking of strengthening zones for foundations and floor slabs was carried out, followed by drilling of injection boreholes Ø45 mm with a depth of up to 2.0 m.

Each house was equipped with 54 boreholes, with a total of 324 injection boreholes completed across six houses.

Through the prepared boreholes, stage-by-stage injection of a gel composite solution under controlled pressure was performed, forming stabilizing injection masses beneath the foundations and floor slabs.

During the execution of the works, continuous geodetic monitoring of elevation changes was carried out, allowing control over the stabilization process of the base.

After completion of the injection, the technological openings were sealed and the surfaces of the structures were restored.

Private residential complex (6 houses)

Leveling of floors and strengthening of foundations

During the operation of several houses within the complex, local and extended subsidence of floor slabs was recorded, indicating uneven performance of the soil base. Additionally, in two houses, strengthening of foundations beneath swimming pool bowls was required due to increased loads on the base and the risk of further deformations.

Engineering inspection revealed the presence of loosened zones and voids in the sub-slab and near-foundation areas, resulting from uneven soil compaction and additional loads from the pools.

Completed works

Specialists of Inject carried out a complex of injection works for leveling floor slabs and strengthening foundations. Within the houses, marking of drilling zones was performed, followed by drilling of injection boreholes Ø45 mm. Each house was equipped with an average of 25–30 boreholes, with a total volume of approximately 160–180 boreholes.

Through a system of injection packers, stage-by-stage injection of a cement-silicate solution was performed under controlled pressure, forming compacted injection masses within the soil base.

In the zones of pool foundations, injection was carried out to a depth of up to 7 m to ensure sufficient bearing capacity of the base. Floor slab lifting was performed gradually using laser geodetic monitoring, which made it possible to achieve precise design elevations without overloading the structures.

After completion of the works, the technological openings were sealed, and the floor coating was restored.

Residential complex “Taychyk”

Stabilization of soils beneath the foundation and the slab of the future floor

At the stage of construction of a private residential house, located in a coastal zone with sandy and water-saturated soils, an increased risk of uneven compaction of the base beneath the foundation and the floor slab was identified.

Taking into account the high groundwater level and the potential risk of future settlement, a decision was made to perform preventive injection strengthening of the soil base before the installation of floor structures. The objective of the works was to form a stable and uniformly compacted base beneath the entire foundation area to prevent possible deformations during further operation of the building.

Completed works

Within the area of the foundation slab and along its perimeter, marking of the injection field was carried out, followed by drilling of 340 boreholes Ø45 mm with depths ranging from 3 to 6 m.

Through the boreholes, stage-by-stage injection of a gel composite solution was performed under controlled pressure up to 8.0 MPa, ensuring uniform penetration of the solution into loosened soil layers and their compaction.

The works were carried out without interruption of the construction process, with continuous monitoring of material consumption and injection parameters, after which the technological openings were sealed.

Private residential house

Stabilization of the terrace and the foundation part of the house

In the area of the terrace, external stairs, and the junction with the facade of a private residential house, local deformations of the coating were recorded: formation of cracks between slabs, opening of joints at the building junctions, distortion of the stairs, and partial detachment of cladding from the plinth.

Engineering inspection revealed that the cause of the defects was local settlement of the soil base, resulting from insufficient compaction of sandy layers and periodic moisture impact in the landscaping zone.

Completed works

Engineering marking of injection zones within the terrace, stairs, and facade junction areas was carried out. Drilling of injection boreholes Ø45 mm with a depth of up to 4 m was performed.

Through installed injection packers, stage-by-stage injection of a gel composite solution was carried out under controlled pressure up to 8 MPa, ensuring filling of voids and compaction of the soil base.

The works were performed without dismantling the cladding and without disturbing the landscaping of the territory.

Private residential house

Strengthening and stabilization of the foundation base without excavation

During the operation of the building, characteristic signs of uneven foundation settlement were recorded: formation of cracks on the facade and internal walls, local differences in floor levels, and a decrease in the rigidity of the structural system.

Analysis of the causes revealed the influence of seasonal groundwater level fluctuations, uneven soil compaction during initial construction, and additional operational loads, which led to gradual loosening of the foundation soil base.

To prevent further deformations and restore the bearing capacity of the soil base, a decision was made to perform bored injection strengthening using a cement-silicate solution without excavation works and without dismantling structures.

Completed works

Engineering marking of injection zones along the perimeter of the foundations was carried out, and an optimal borehole layout scheme was determined. Through the existing coating, 60 injection boreholes Ø45 mm with a depth of up to 4.0 m were drilled.

Through installed injection packers, stage-by-stage injection of a cement-silicate solution was performed under controlled pressure with regulated control of injection volumes.

During the injection process, local injection inclusions and overlapping compaction zones were formed, ensuring the creation of a stabilizing soil-cement mass beneath the building foundations.

The works were carried out without excavation, with external access to injection zones and full preservation of the landscaping. After completion of the injection, the packers were removed, and the technological openings were sealed.

Private building

Increase of the bearing capacity of the soil base prior to superstructure construction

As part of preparing the building for the addition of an extra floor, it was established that the bearing capacity of the soil base beneath the existing structures was insufficient to accommodate the future design loads.

To prevent possible uneven settlement and ensure stable performance of the foundations, a decision was made to carry out injection strengthening of the soil base beneath the existing floor slab without dismantling structures.

Completed works

At the site, marking of the injection field was carried out, followed by drilling of injection boreholes Ø45 mm with a depth of up to 4 m, arranged in a staggered pattern with a spacing of 0.8–1.0 m.

In total, up to 350 boreholes were installed, through which stage-by-stage injection of a gel composite solution was performed under controlled pressure up to 8 MPa, forming a spatially compacted stabilization mass within the soil base.

The works were carried out during the winter period at temperatures down to –20 °C without the use of winter additives. To ensure stable material supply, local heating of the injection equipment and solution was applied, allowing maintenance of the required viscosity and controlled injection rate.

Private house

Lifting of a subsided floor and stabilization of the base without dismantling

In a private residential house, local subsidence of the floor slab was identified, which led to the formation of gaps between the fireplace and adjacent structures, as well as unevenness of the floor covering.

Engineering inspection revealed the presence of voids beneath the floor slab with a thickness of up to 200 mm and a decrease in the density of the soil base, which created a risk of further deformations and damage to interior finishes.

Completed works

Engineering marking of injection zones within the deformed part of the floor was carried out. Drilling of 27 injection boreholes Ø45 mm with a depth of up to 4 m was performed.

Stage-by-stage injection of a gel composite solution was carried out under controlled pressure with geodetic monitoring of structural lifting.

During the works, filling of identified voids beneath the floor slab, compaction of the soil base, and formation of a stabilizing injection mass were ensured.

After completion of the injection, control geodetic measurements were carried out, and the technological openings were sealed.
