thumb_M261 St Cleres Bridge is an underbridge located on the M26.  Topbond were commissioned by the Highways Agency, to undertake structural upgrading works to the parapet edge beams in preparation for parapet refurbishment works.

Part of the works required the installation of additional sections of concrete to the bridge which required new starter bars to the drilled and resin grouted into the original deck.

Topbond called upon the services of HTS, its in-house testing division to undertake pull out tests of the resin anchored bars.  HTS used a hydraulic test rig to apply to desired proof load to the embedded reinforcement and were able to confirm on site, to the client’s representative, that the tests were successful.
