Geological–Geotechnical Reports for Building Permits

Why do you need a geotechnical report for a building permit?

In accordance with Slovenian legislation, a geotechnical report for a building permit is a mandatory part of project documentation (DGD and PZI). The purpose of the report is to determine the actual site conditions before the first excavation begins. Without accurate data, you risk differential settlement, cracks in walls, or even catastrophic damage due to landslides.

Preparing a geological report in our company includes a comprehensive site assessment, ensuring your investment is protected from unforeseen geological processes.

Soil analysis and foundation conditions

The core of every investigation is a detailed report on soil stratigraphy and properties. Based on field investigations—such as trial pits or drilling—we determine the physical and mechanical properties of the layers beneath your future structure.

Bearing capacity of foundation soil and foundation depth

The most important parameter for the structural designer is the bearing capacity of the foundation soil. This value determines how wide and how deep the foundations must be. Foundation depth must always be designed below the frost zone and within sufficiently competent layers to prevent structural damage.

Geological services in Slovenia: From Ljubljana to the coast

As a leading provider of geological services in Slovenia and specialists in geotechnics in Ljubljana, we understand local specifics. Ljubljana and its surroundings require a special approach due to characteristic clay deposits and high groundwater levels.

Landslide assessment report and erosion hazard

In hilly areas, stability assessment is crucial. A landslide hazard report analyzes the risk of slope movement. If erosion risk is identified, we propose measures such as drainage systems, retaining walls, or vegetative protection so that your home remains safe even during extreme weather events.

Hydrogeology and stormwater management

Modern environmental regulations require strict water management. A hydrogeological report is the basis for obtaining a water consent issued by the Slovenian Water Directorate (Direkcija RS za vode).

• Infiltration (soakaway) potential: We verify the soil’s capacity to absorb rainfall runoff.

• Stormwater infiltration report: A document proving that stormwater from your plot will not endanger neighboring land or public infrastructure.

• Risk assessment for pollution of the water body: Essential when building in water protection zones, where we assess the impact of the structure on drinking water resources.

Cooperation process: From plan to permit

To start, we need your geodetic survey plan, which serves as the basis for determining the locations of test pits and boreholes. Our process is transparent:

1. Site visit and field investigations: We carry out trial pits and, if required, laboratory testing of samples.

2. Calculations and analysis: We determine bearing capacity, settlement, and stability.

3. Preparation of documentation: We prepare the final report aligned with building permit requirements.

The project documentation you receive is prepared professionally, clearly, and in accordance with all Eurocode 7 standards.
