With its revolutionary new load transfer system and by utilizing state-of-the-art materials, the BBR VT CONA CMI Post-tensioning System (European Technical Approval ETA 06/0147) allows closer anchor spacing, stressing at a lower concrete strength and reduces reinforcement in the anchor zone. Compared to Conventional Systems the CONA CMI requires: 20% to 40% less space in the Anchorage Zone and a lower concrete strength at the time of stressing!
