Crack & Foundation Repair - Powderham Castle, Devon

Powderham Castle in Kennford, Devon has remained in the family of the current occupiers, the 18th Earl and Countess of Devon, since it was built in 1391.

Target were asked by local consulting engineers to design and install masonry reinforcement and Heli Pile foundations to stabilise the incinerator tower, which was in a state of disrepair.

Target liaised with English Heritage and the conservation officer to ensure that the method of work would be sympathetic to the original materials prior to carrying out any work on site.

Bar Flex reinforcement was chased into the existing bed joints of the stone work and Cem Flex ties were inserted to support the failing arches and to cross stitch internal cracks.

Heli Pile points were driven both internally and externally and then cast into seperate ring beams. Large diameter diamond cores were drilled through the wall to enable steel beams to pass through and then cast onto the ring beams allowing Heli Pile to take over the loads being transferred to the foundation stones.

The whole tower was then re-pointed in a specially mixed lime mortar to closely replicate the original material used.
