Geotehnical investigation

Geotechnical investigations and testing of foundation soil form a crucial basis for any construction project. We conduct geotechnical investigations for the design of new structures, as well as for the condition assessment and remediation of existing ones.

Services

Research services include:

  • Preparation of investigation programs,
  • Execution, coordination, and supervision of field investigation works:
    • Geological, engineering-geological, and hydrogeological investigations
    • Groundwater exploration
    • Geophysical surveys
    • Exploratory drilling and trial pits
    • Sampling
  • Preparation of foundation soil investigation reports / Geotechnical reports

We carry out all geotechnical investigation works in accordance with Croatian standards and applicable technical specifications.

In Situ testing of foundation soil
  • Standard penetration test – SPT
  • Field wing probe test – FVT
  • Water permeability test – VDP
  • Electric static penetration test with pore pressure measurement – CPTU
  • Dynamic penetration test – DPL,DPM,DPH,DPSH
Research Equipment

Reliable equipment for precise research

Geotechnical investigations and testing constitute a key foundation for any construction project. To ensure the high-quality and reliable execution of investigative work, we utilize modern equipment that enables precise field and laboratory testing, as well as the collection of all data necessary for design and analysis.

Crawler-mounted hydraulic drill rig. It is equipped with an automatic SPT system and the associated equipment and accessories for conducting exploratory drilling in soil and rock, as well as for sampling and performing in-situ tests within boreholes.
