The Project

This end of terrace, two-storey property is divided into two flats.  The 500mm thick stone front and end gable walls were bulging and rotating outwards and there were concerns over the long-term stability of the building.

James Lockyer Associates recommended that the walls be tied back to the first floor structure by installing lateral restraint ties through the walls and into the floor joists to prevent further movement.  Concealed tie bars were installed in the gable wall and tie bars with external pattress in the front wall, which involved removing the ceiling in the ground floor flat.  The external sand/cement mortar was removed and the joints repointed with lime mortar which is more compatible with stone masonry walls.

The building borders a primary school so the works were delayed until the school summer holidays to maximise safety and minimise disturbance.  In the interim, the walls were monitored for significant movement.
