Lateral Restraints - Take a Bow
The walls of a property certainly deserve an applause for all their hard work, but if they start to bow as well then it's time to get Twistfix on the situation! Bowing, bulging or otherwise leaning external walls point to a lack of lateral restraint that requires an immediate fix.
Generally, house walls are structures that are particularly slender in ration to their height; it is this fact that leaves them vulnerable to buckling forces. Restraint is usually provided in two ways; by securing external walls to floor diaphragms and by strapping façade walls to the brick-bonded buttressing partition walls that run right-angles to them.
Once again, it is older buildings that bear the brunt of this structural issue and the problems often occur when the restraint between the external walls and the floor joists and partitions are defective, inadequate or even missing altogether.
The lateral restraint tie is an incredible innovation that, like so many others, is taken for granted. The retrofit tie rods are used when the façade of a building has become disjointed from the main structure, providing reconnection and enhancing resistance to thrusting and buckling forces. Drill-tipped tie-rod systems are specifically designed to tie external walls to timber joists located in structural floor diaphragm or to stud; they can also be used with stud walls.
The range of lateral restraint systems is large and diverse, in reflection of the differences between structures. Our long-series 12mm diameter heavy duty helical ties are designed to reconnect and strengthen masonry wall junctions, which is a particularly efficient method of transferring lateral forces back to buttressing walls.
Combining various types of restraint types is noted for its benefit of forming small box-like structures within the larger structure, dramatically increasing lateral restraint and stabilising the external wall.
