Geotechnics - investigations of building ground and underground

Would you like to know how robust your building ground is? Your building has subsided and you would like to know why? We will find it out! We offer specific and individual investigations for each project. With your support, we will define your specific requirements.

In order to determine the properties of the soil, we offer you the following field work:

– Dynamic penetration tests in accordance with DIN EN ISO 22475-1
– Dynamic penetration tests in accordance with DIN EN ISO 22476-2 (DPL, DPM, DPH)
– Compaction checks using dynamic and static plate load tests
– Disturbed and undisturbed soil samples
– soli profiles in accordance with DIN 4022/DIN 4023 or DIN EN ISO 14688-1/DIN EN ISO 14689-1
– infiltration tests in boreholes or open-end tests (OET)
– Core drillings for sealed surfaces (asphalt/concrete)

This field work is followed by laboratory testing. In our engineering laboratory, we carry out standard test methods for determining soil physical properties (soil mechanical laboratory tests):

– Sieve analysis
– combined sieve and sedimentation test
– determination of loss on ignition
– determination of consistency in cohesive soils
– determination of water content

The data collection from the field and laboratory is followed by the preparation of short statements (preliminary exploration) or comprehensive structural engineering statements.

We are also able to carry out an indicative chemical analysis from the soil samples obtained – in accordance with the Mantelverordnung 2021 (in particular the Substitute Building Materials Ordinance under the Federal Soil Protection Act or the Landfill Ordinance). This does not replace a declaration for recycling/disposal.

In the event of anomalies, this would be necessary via a pile sampling in accordance with PN98 and subsequent analysis. We are happy to advise you on this matter.
