Our Services
Field Investigations
We perform a wide range of field tests in accordance with SRPS U.B1.010 and SRPS EN 22475-1, including:
- Mechanical drilling and sampling of disturbed and undisturbed soil samples to depths of up to ~30 m
- CPT – static cone penetration
- CPTU – static cone penetration with pore pressure measurement
- SPT – standard penetration test
- DPA – Dynamic Penetration Analysis
- Installation of piezometers and hydrogeological testing of boreholes
- Automatic groundwater level monitoring
- Excavation of test pits
- Determination of compressibility and deformation modulus using plate load tests
- Pile load test up to 300 t (static load test)
Laboratory Testing
Our laboratory is equipped for the complete identification, classification, and mechanical testing of soils and construction materials:
- Determination of soil moisture content
- Determination of bulk density (with or without voids, by cylinder or calibrated sand method)
- Particle size distribution analysis
- Atterberg limits (plastic and liquid limits)
- Determination of carbonate, organic, and combustible content
- Direct shear test
- Oedometer testing for compressibility
- Unconfined compression strength testing
- Proctor and CBR tests – compaction and bearing capacity assessment
- Determination of optimum moisture content and dry density
Geotechnical Reports and Design Recommendations
Based on the executed field and laboratory investigations, we prepare geotechnical reports that synthesize and interpret all obtained data.
The report includes:
- Interpretation of investigation results
- Graphic presentation of borehole logs and stratigraphy
- Engineering-geological cross-sections
- Charts and tables of geomechanical parameters
- Hydrogeological assessment and seismic site characterization
- Recommendations for foundation design and selection of the most suitable technical solution
