For the adequate replacement of damaged natural stone of your asset, our experts offer the determination of the origin of the used stones. With the help of microscopic, spectroscopic and X-ray diffractometric analyses we can determine the detailed composition and recommend a suitable replacement material.

With regard to damage caused by weathering and environmental pollutants, our experts analyse the diverse natural stones of your objects with regard to mineralogical, mechanical, physical and chemical characteristics and properties. Our well-equipped examination facilities guarantee you a comprehensive assessment of your asset's condition and evaluation of the causes of any damage that has occurred.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi, Corinna Luz

We offer you damage analysis and the adjustment of formulas, testing and determination of the chemical-mineralogical composition of historical and modern artificial stones and concretes. Our team of experts uses microscopic and wet chemical analysis to identify and describe the originally used binders and aggregates. With wet chemical separation and sieve analysis or image evaluation on thin sections, we can provide you with reliable information on the type, grain size and grain shape of the aggregates used and the binder/aggregate ratio.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi, Corinna Luz

We offer you a series of chemical-mineralogical tests for the investigation of the causes of damage to your object. Depending on your requirements, we use chemical analysis with X-ray fluorescence (XRF, DIN 51418) ), ion chromatography (anions and cations, DIN EN ISO 14911 and DIN EN ISO 10304), phase determination (XRD, DIN EN 13925), i.e. the direct identification of chemical compounds.

The knowledge of material moisture is of outstanding importance for the repair and preservation of historical buildings and structures. Our experienced field service team can carry out in situ measurements on your premises or take appropriate material samples, determine all necessary moisture-related parameters in the laboratory, and evaluate the results.

The water absorption behaviour of natural stone and other weathered materials is decisive for assessing the weathering behaviour. We determine the water absorption behaviour of your object in situ using capillary water absorption (test tube according to Karsten). We carry out capillary water absorption on building material samples of your object according to DIN EN 772-11.

Investigation of hygroscopic sorption properties according to DIN EN ISO 12571 on porous building materials with the reference method (desiccator method) and using a computer-controlled climate chamber, GraviSorp 120. Due to the possibility of setting small step sizes between 1% r.h. and 98 % r.h., we can record sorption isotherms and, for example, evaluate the damage potential of salts harmful to building materials.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi, Corinna Luz

Knowledge of the extent, concentration and type of salt contamination is essential for the preservation of historical objects and especially of buildings made of natural stone. Our experienced team uses mobile non-destructive test methods (e.g. Raman and near-infrared spectroscopy) to determine the near-surface salts. By sampling and laboratory investigations (e.g. ion chromatography and X-ray diffraction) the salt load is further verified, quantified and evaluated.

The use of salt reduction methods aims at reducing the concentration of salts harmful to buildings in mineral building materials as non-destructively as possible. A reduction of the salt content is often a mandatory prerequisite for sustainable restoration measures: The formation of salt crystals is stopped or slowed down or the implementation of further measures, such as stone consolidation, is made possible. Salt reduction is achieved, for example, by compress desalination or the vacuum suction method. We support you in the evaluation of the success and estimation of the expenditure by analytical examination.

Microscopic thin-section analysis and examination under the electron microscope are essential for the reconstruction of historical mortars and artificial stones, the detection of ASR damage to concrete and the replacement of damaged natural stones. Our expert team of geoscientists can examine your historical and modern building material samples with regard to composition and microstructure.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi

To determine and test a suitable stone strengthener for natural stone restoration, we test the drilling resistance of unstrengthened and strengthened sample stones on your object. The test is slightly invasive and allows a comparative evaluation of the achieved strengthening success of different stone strengtheners and application techniques.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi

We use the methods of thermal analysis (DIN 51005) to study temperature-dependent material properties. We determine typical parameters for material characterization, such as decomposition temperatures, temperature stability, oxidation stability, quantitative composition, transformation temperatures and enthalpies with simultaneous thermal analysis (Netzsch STA 409). We determine glass transitions with the differential scanning calorimeter Mettler DSC 822.

Contact: Dr. Friedrich Grüner, Dr. Judit Zöldföldi, Corinna Luz

A precise damage analysis of structures may require the consideration of time-dependent influences and loads. These include, for example, temperature, rain, solar radiation or mechanical loads from traffic and wind. With the help of a suitable instrumented monitoring system, the origin of existing damage can be determined and future damage may be avoided. Our engineers will design a suitable concept with you and install and operate a monitoring system adapted to your needs, with classic electro-mechanical or fibre-optic sensors, wireless or wired. You can find further information on structural health monitoring here.

Especially with regard to corrosion, but also for fire protection and for static reasons, a sufficient concrete cover of the steel reinforcement is essential. Our experienced field service team can efficiently determine and document the concrete cover on your object with non-destructive test methods.

Contact: Dr. Frank Lehmann

There are often no or only insufficient reinforcement plans for existing buildings. Our competent employees have a choice of different measuring methods to determine the position, amount and diameter of the existing reinforcement with non-destructive or minimally invasive test methods. Subsequent examinations, e.g. regarding corrosion, are carried out in cooperation with our colleague experts.

Contact: Dr. Frank Lehmann

For the quality assurance of fresh concrete, mortar and other hydrating materials, our measuring system FreshCon provides you with a method allowing the reproducible, objective observation of the progressive solidification and hardening of the material, fully automated from the moment the water is added.

Contact: Dr. Frank Lehmann

Used mainly in the construction industry on mineral materials and soils. The method is particularly suitable for locating slack and prestressed reinforcement as well as metallic mounting parts in concrete. For this purpose, an electromagnetic wave is sent into the component to be examined and the reflection is evaluated. We offer radar measurements as an independent test method for structural investigation and use it additionally for other measurements, e.g. for magnetic leakage field measurements.

Contact: Michael Schreiner

Similar to the ultrasonic method, impact echo can also be used to non-destructively determine the thickness of structural components. The method is relatively insensitive to inhomogeneities and reinforcement.

Contact: Dr. Frank Lehmann

Prestressed concrete structures owe their high load-bearing capacity and concurrent slim design to the integration of pre-stressed steel reinforcement. In most structures, this steel is embedded into the concrete and therefore not visible from the outside. It is thus not easily accessible for inspection. At the MPA University of Stuttgart, our engineers and scientists have developed a test method based on the applicaton of a magnetic field, that can be used to inspect the embedded prestressing steel for damage, especially fractures. Direct contact with the reinforcement is not necessary. This test is particularly relevant for the assessment of bridges in existing structures (recalculation guideline), but also for other long-span structures, such as gymnasiums and other halls. Further information on the test method can be found here.

Contact: Michael Schreiner

Damage to a structural part occurs under mechanical or thermal stresses. The cracking releases elastic waves in the material. These waves can be detected with a suitable transient recorder and extremely sensitive sensors. Using a suitable measuring device, we can determine the source of the signal and thus the location of the damage - even before it becomes visible to the human eye on the surface or before the component as a whole is damaged. We can use our measuring equipment for laboratory tests as well as on site at your project.

Our certified experts offer you a wide range of non-destructive and classical methods for damage analysis. Please feel free to contact us!

Used for non-destructive testing of mineral, metallic and other solid materials in the construction and engineering industries. The object to be examined is sounded with acoustic waves. The reflected or transmitted wave is recorded and evaluated with regard to transit time, wave form or frequency content. Our experts can draw conclusions about material thickness, inhomogeneities, inclusions and embedded components, delaminations, material moisture and much more. We offer the performance of the measurements in the laboratory and on site.

Contact: Dr. Frank Lehmann

To determine and assess the remaining service life of reinforced and prestressed concrete structures (e.g. bridges), our employees determine carbonation depths and the chloride content of the concrete. Furthermore, the installed reinforcing and prestressing steels can be assessed for their corrosion condition with regard to their load-bearing capacity. On prestressing steels we can check the susceptibility to stress corrosion cracking.

Using metallographic grindings, our employees can determine the microstructure of materials, identify material defects, determine the causes of damage, show the thickness of corrosion protection layers and determine material characteristics such as hardness or roughness of surfaces. It can also be used to identify corrosion mechanisms such as pitting, crevice corrosion, stress corrosion cracking, intergranular corrosion, etc. The examination and assessment is carried out using a light microscope, digital microscope, stereo microscope and scanning electron microscope (SEM). By energy dispersive X-ray spectroscopy (EDX) we determine the chemical composition of materials, deposits and corrosion products.
