Consultancy
Research and technical consulting (a complete service for architects, surveyors, and for clients direct). This includes on site sampling, inspection and testing, laboratory testing, evaluation of materials and provision of comprehensive reports including repair recommendations. Consulting in whole broad area of the buiding chemistry and in the fields of buildings, structures and construction materials.
Diagnostics
We offer a complex range of structural diagnostic examinations. Most tests are carried out in-situ in a non-destructive wayat minimum costs. The result and the reports are used as a basis for the assessment of structures, for the determination of their load-bearing capacity and for further design stages in compliance with the clients requirements.
