Making post-installed rebar connection quicker 22 February 2023

A new injection mortar product, the RebarConnect FIS RC II, which not only makes post-installed rebar connections quicker, but also safer and more efficient, is being launched by fischer Group. 

Reinforcing bars embedded in mortar are increasingly used in new builds, as well as during renovations and conversions of existing buildings. Indeed, post-installed rebar connections are invaluable in everyday construction, whether for connecting new walls, columns and stairs, closing existing floor openings, or creating floor plates, concrete covers or foundation extensions – with heavy-duty chemical fixings frequently used for such applications. 

fischer’s new ETA-compliant RebarConnect FIS RC II vinylester hybrid mortar provides concrete construction specialists with a secure and efficient solution for post-installed rebar connections. Its European Technical Assessment (ETA) covers applications using 8mm to 32mm diameter reinforcing bars that are embedded at depths of up to 2m. Short processing and curing times enable quick work progress in drill holes created either with hollow or hammer drills. 

The anchor substrate can function at temperatures between -10°C and +40°C and, according to the ETA, this makes it suited to a wide range of applications. FIS RC II has also been approved for post-installed rebar connections with a service life of 100 years and in such applications the injection mortar’s ETA enables its use in designs requiring fire resistance up to class R 180. The new substrate is available in container/shuttle cartridge sizes of 360ml and 825ml, which are suited for use with battery-operated dispensers, FIS DB S Pro and FIS DB SL Pro. 

Alongside the RebarConnect FIS RC II, fischer also offers access to a reliable and safe programme for designing post-installed rebar connections – available with the REBAR-FIX module from the fischer FiXperience software suite. Depending on on-site options and requirements, the REBAR-FIX programme enables verification in line with various standards and guidelines. The company’s technical field service and technical hotline are also available in case users have any queries and the fischer Academy offers e-learning training on post-installed rebar connections through live online and in-person seminars. The programme contains regular training sessions that, on completion, allow participants to obtain certification from the German Institute for Structural Engineering – German companies and tradespeople require this certification in order to be allowed to execute post-installed rebar connections.
