Engineering geology
Geological soil investigations are the foundation of every successful construction project, as they provide precise understanding of the composition, bearing capacity, and stability of the ground. Based on this data, it is possible to ensure safe foundation design, select appropriate construction methods, and reduce risks during building.
Engineering geology, as an applied branch of geology, studies geological conditions and geologically induced hazards that arise during the planning and construction of structures. Engineering geologists carry out soil investigations and analyses before and during interventions in the natural environment, and they also participate in remediation works after natural disasters such as floods, landslides, rockfalls, and earthquakes. In doing so, they help reduce risks and damage, while protecting lives and property from the consequences of hazardous geological processes.
Our geological soil investigations include field surveys, laboratory analyses, and professional interpretation of results. Through them, we determine the mechanical properties of natural materials, produce engineering–geological terrain maps and geological profiles, and provide a comprehensive insight into the geological characteristics of an area. The most important geological parameters in this process are: geological–lithological structure of the terrain, groundwater level and occurrence, mechanical condition of rocks and sediments, and surface stability.
With many years of experience, we carry out geological soil investigations for residential, industrial, and infrastructure projects. Through expertise, precise analyses, and adherence to the highest standards, we ensure reliable foundations for the design of geotechnical structures, rehabilitation of existing facilities, and sustainable land management.
Based on field surveys, knowledge of the terrain, and basic data on the planned interventions in the area, the necessary scope of geological–geomechanical investigations is determined to ensure proper site testing and long-term stability of structures.
During and after construction, engineering geologists, on the basis of slope and structure stability assessments as well as the analysis of geodetic and inclinometer measurements, prepare reports on terrain stability. They also issue expert opinions and studies on the actual erosion risk of the terrain prior to planned interventions.
Our services :
Geomechanical borehole drilling with SPT and pressuremeter measurements represents a comprehensive approach to in-situ soil investigation. While the SPT (Standard Penetration Test) provides data on soil density and resistance through dynamic probing, the pressuremeter allows determination of soil deformation and strength properties by means of radial loading of the borehole walls. The combination of both methods ensures a reliable assessment of bearing capacity and foundation behavior under real geological conditions.

Jetmir Rakovec
Feedback from a construction company: “Working with your company left us with only positive impressions! The geological investigations for our project were carried out professionally and in the shortest possible time. All recommendations were clear and precise, which allowed us to avoid unnecessary costs during the construction phase. Special thanks for the detailed reports and your attentive approach to our requirements!”

We required a geological report for the design of a residential house. The Geoinženiring team responded promptly, carried out the drilling and investigations smoothly, and without complications. Communication with the geologist was clear, professional, and timely. We are very satisfied with their approach.
Astrid Cvikl
I commissioned a geological survey for a house construction site and was very satisfied! The experts explained all the results in detail and provided clear recommendations regarding foundation selection. I was impressed by their high level of professionalism and friendly attitude. I highly recommend this company to anyone seeking reliable geological services!
