Lateral Restraints

The restraint of external walls is often provided by floor joists and purlins spanning onto a wall together with buttressing cross walls; however, the presence of stairwells, parallel joists and stud cross walls will deny restraint. A lack of lateral restraint may cause the wall to bulge, particularly to areas where cavity wall tie corrosion has occurred.

It is possible to install new lateral restraints by fixing stress free masonry re-inforcing products through the masonry and into adjacent floor joists. This work can be undertaken with minimal disruption to the external face of the building.
