On-site Membrane Stress Measurement from DEKRA
DEKRA Laboratory for Technical Textiles and Films tests membrane structures on site in its capacity as monitoring body and for the preparation of expert reports. The membrane stress measuring device (MSM II), which was specially developed by the laboratory, checks the prestress in tensile membrane surfaces after assembly or as part of recurring inspections, thereby helping to prevent damage.

DEKRA Laboratory for Technical Textiles and Films in Stuttgart is an independent testing laboratory recognized in accordance with German Building Regulations (LBO). It also has DAkkS accreditation in accordance with DIN EN 17025 for testing methods in the field of films and fabrics. The laboratory possesses leading knowhow and decades of experience in the field of membrane construction. The experts support manufacturers, planners and contractors in all aspects of technical textiles. The laboratory is actively involved in numerous spectacular lightweight construction projects worldwide—including various football stadia in Germany and abroad and the façade of the striking Rottweil Elevator Test Tower owned by ThyssenKrupp.

The laboratory tests mechanical and structural properties, develops new measuring methods and testing equipment and supports companies in quality assurance. Stationary test benches in the laboratory enable bi- and multi-axis testing of films and technical textiles.

But for many projects, the team’s knowhow is also required on site. The DEKRA experts not only perform damage analyses on buildings, but also regularly assess the condition of façades and roofs covered with membranes or films. Inspection drones are used in areas that are difficult to access.

The mobile DEKRA membrane stress measuring instrument measures the stresses in a membrane of a building, thereby helping to prevent damage. All membrane materials can be calibrated, the menu is multilingual, the device presents the measurement results in graphical form and makes documentation easy thanks to its ability to store multiple measurement points.

DEKRA Laboratory for Technical Textiles and Films will be at Techtextil from May 14 to 17, 2019, in Frankfurt am Main (hall 4.1, stand L 46).
