Bridge bearings

VolkerLaser provides specialist upgrading and replacement of bearings including mechanical, elastomeric and rocker and roller bearings.

The bearings on a large proportion of the UK's aged bridge stock are now coming to the end of their service life, and require upgrading or replacement. VolkerLaser has the capability to deliver these essential works, with a proven track record of success.

Cleethorpes Road Overbridge

VolkerLaser delivered an innovative solution when replacing 512 no. bearings at Cleethorpes Road Overbridge. The geometrical arrangement of the tapered piers meant that the foundations were not directly beneath the bridge beams, so additional jacking foundations needed to be constructed. Excavating to do this would have run the risk of encountering unforeseen ground conditions and generating a large expense to the client.

VolkerLaser constructed reinforced concrete corbels stitched to the existing piers from which to jack the bridge. A specialist temporary works designer was appointed in order to develop this idea into a robust scheme. The corbels were designed to provide support to the jacking system to lift the deck during the bearing replacement operation, thus eliminating the need for any works at ground level.
