The BBR® Network offers a complete range of post-tensioning systems, covering all possible applications in structural and civil engineering. Developed in Switzerland, the European approved and CE-marked BBR VT CONA® CMX PT range – the PT system for the 21st century – is used worldwide by the BBR Network. Our certified BBR PT Specialists ensure professional execution of PT and grouting works.
BBR VT CONA CMX
The newly developed BBR VT CONA CMX family has been tested to the most stringent international testing specifications – those of the European Technical Approval Guidelines ETAG 013. Its modular design means that a CONA CMX PT kit can easily be configured to match special requirements. All systems are subject to Factory Production Control (FPC), as well as independent and continuous surveillance. All CONA CMX kits must be installed by trained BBR PT Specialist Companies only, ensuring a professional and system-conforming installation. All requirements are strictly followed by the BBR Network and ensure the highest level of product quality and installation, including best health and safety standards.

Other BBR PT systems
The BBRV® wire cables are one of the earliest and most reliable post-tensioning systems. This parallel wire system was developed by BBR in 1944 and has since been continuously advanced. Furthermore, the CONA compact, CONA multi, CONA single, CONA flat and CONA external strand post-tensioning systems have been applied very successfully for many decades.
