Mineral Building Materials

We combine engineering services with research and modelling as well as testing and inspection/certification.

Your professional partner for all mineral building materials

We offer you comprehensive advice and support in all matters relating to investigations, tests, research/modeling and inspection/certification (LBO, BauPVO and voluntary certification programs (e.g. Keymark)) of mineral building materials and constructions. Our wide range of services covers all aspects of consulting in the planning of construction work, on-site monitoring, on-site investigations, laboratory investigations and numerical modeling. We are happy to advise you on your specific request.

The Units in our Department

Concrete Technology, Rehabilitation

The staff will advise and assist you in solving technical issues to determine the condition and maintenance of solid structures. In the production and processing of concrete, our employees work as supervisors, consultants and inspectors. In case of damage, we offer expert support. We provide chemical, physical and mechanical-technological investigations for the characterization and evaluation of mineral building materials and damage processes to which these building materials are exposed.

Material Behavior and Modelling

Solutions for all aspects of the material behavior of quasi-brittle materials. Through an optimal combination of experimental and numerical investigations, we can offer you a reliable solution to your questions. Supported by the institute's own 3D finite element software MASA, the behavior of various materials (concrete, reinforced concrete, masonry, natural stone, etc.) under different types of stress (mechanical/thermal, both static, cyclic and dynamic occurring and stresses due to steel corrosion) can be examined.

Building Envelope, Energy Efficiency, Floor Constructions

Our experts offer comprehensive advice and examinations of masonry, plasters, ETICS, insulation materials and floor constructions/sports facilities. The area of activity covers all aspects of building materials testing, damage investigations and the preparation of expert’s reports. For the inspection/certification of your construction products we are accredited according to LBO and BauPVO (DAkkS accreditation).

Tasks and technical focus

We offer chemical, physical and mechanical-technological investigations of mineral building materials such as binders, fly ash, silica fume, rock flour, aggregates, mortar, concrete, natural stone, building products for masonry construction, insulation materials etc. as well as testing of sports hall floors, raceways, impact protection wall systems and safety against ball throwing. Inform yourself here about the services offered by us or contact us by phone or email!

As a PÜZ body according to LBO and BauPVO we are notified by the DIBt and approved to perform tests for technical approvals. We are accredited by DAkkS as a Certification Body and Testing Laboratory. Inform yourself here about the services offered by us or contact us by phone or email!
