Geotechnical Laboratory
Create reliable test results. Make confident decisions.
In our accredited geotechnical laboratory, we examine soil and building material samples using standardized testing procedures and modern measurement technology, thus creating a reliable basis for geotechnical assessments, planning and quality assurance – precise, reliable and practical.
Soil mechanics baseline investigations
Basic soil mechanics investigations provide the key parameters for assessing subsoil, soils, and building materials. They form the basis for geotechnical calculations, foundation design, and the evaluation of materials in earthworks and foundation engineering.
Services:
-
Classification & state boundaries:
Water content, Atterberg limits, grain size distribution and lime content -
Density & Storage:
Grain density, soil density, bulk density and Proctor density (Type A–C) -
Strength & Deformation:
Uniaxial compression and shear tests as well as shear and vane shear tests -
Water balance & permeability:
Loss on ignition, water absorption capacity and permeability tests on cohesive and non-cohesive soils
Special geotechnical investigations
For specific geotechnical issues, we conduct specialized laboratory tests on soils, aggregates and geosynthetics.
This allows us to evaluate material properties and interactions for demanding construction and infrastructure projects.
Services:
Large frame shear tests:
On cohesive and non-cohesive soils as well as on interfaces with polymeric componentsGeotextiles & sealing systems:
Water permeability tests on geotextile drainage and clay sealing systemsSoil physics special tests:
Freeze-thaw cycles, swelling capacity, and field, air, and usable field capacityThermal properties:
Determination of thermal conductivity and thermal resistanceAggregates:
Petrographic description, grain shape, flatness and Los Angeles test method
Geotechnical field tests & construction supervision
As part of our geotechnical construction supervision, we inspect and document the execution of earthworks and civil engineering projects. This ensures that geotechnical requirements and specified quality standards are met.
Services:

Dynamic probing:
Light, medium and heavy dynamic probing -
Densitometer tests:
Control of compaction and installation quality -
Construction monitoring and documentation:
Verification of geotechnical requirements during construction
Technical Analysis and
Ecological Design
As a materials testing laboratory for flowable fill, we conduct qualified tests and certifications according to the requirements of the RAL Quality Mark 507. In doing so, we support construction projects with quality assurance, internal and external monitoring, and structural engineering questions related to the use of flowable fill.
Services:
Compressive strength & modulus of elasticity:
Determination of mechanical properties of flowable fillThermal conductivity:
Testing using a penetration probeWater permeability:
Determination of the water permeability coefficient in the triaxial test
