The BBR Network offers a complete range of post-tensioning systems, covering all possible applications in structural and civil engineering. Its modular design means that a CONA CMX post-tensioning kit can easily be configured to match very special requirements. This listing includes the following systems: BBR VT CONA CMI The BBR VT CONA CMI post-tensioning system is a multistrand system for all types of internally post-tensioned applications. BBR VT CONA CME The BBR VT CONA CME post-tensioning system is a multistrand system for all types of externally post-tensioned applications. External tendons are placed on the outer surface of concrete structures. This type of post-tensioning allows access for maintenance and replacement and is therefore the solution of choice for maintenance, repair and retrofitting (MRR) of bridges, but can also be applied to many other types of structures. BBR VT CONA CMB The BBR VT CONA CMB post-tensioning kit is a multistrand system for special external and also internal unbonded post-tensioned applications.
