Contract Details

Cumnor Construction Ltd. carried out the role of Works Contractor and PSCS for this project.

The wall dates back to the early 17th century. The contract comprised of the conservation of this National Monument and the work was subject to regular inspection by a Conservation Engineer and Archaeologist.

The work involved stabilising two sections of wall by using tie-backs of reinforced concrete. A reinforced concrete base and column was constructed against the existing wall. Stainless steel tie bars were then used to support the existing wall, held within this new concrete pour. Stainless steel plates were fixed to these tie bars to support the wall.

The stone wall cap was reset using lime mortar and the top of the wall was flaunched. Parts of the wall were repointed as required. This involved raking out the deteriorating mortar and the installation of natural hydraulic lime. Edge kerbing, tarmac and gravel surfaces were reinstated along with installation of drainage to the rear of the wall.

The works bounded a public road and therefore a traffic management plan was designed and implemented.
