As part of the Structural Repair works we carried out a Structural repair Survey in order to diagnose the causes of cracking and movement and to design a suitable repair scheme that would restraint all Structural Movement.

The first phase of works are to 5 No 1940’s built properties built using cavity wall construction which were suffering from cracks at the junctions of the outside walls and the internal masonry partition walls.

In order to prevent any further movement we specified Twistfix Helical rods to be installed into the external bed joints, drilled into the internal masonry partition walls and then grouted into the masonry creating an L shaped tie resisting any further outward movement.

Horizontal Cracking In Mortar Beds

Horizontal cracking to the external masonry of a property that is of cavity construction indicates a serious structural defect which will need to be investigated by a specialist.

In the most common instances short horizontal cracks within the mortar bed will indicate that the wall ties have failed and are suffering from oxidisation.

Wall Tie Failure
Wall Tie Failure

With a failure in the wall tie caused by corrosion iron oxide layers build up on the tie increasing the ties mass, lifting the brick which separates the brick from the mortar it was laid on to therefore the connection between the internal skin of masonry and the external skin of masonry is lost leaving the potential for collapse of the masonry which has happened.

If you have horizontal cracking to the external skin of masonry you should initially contact a wall tie specialist like ourselves and have an intrusive Wall Tie Survey carried out so that the cause of the cracking can be diagnosed and a suitable repair scheme implemented.

Wall Tie Replacement is a delicate process which although appears simple should not be deemed so. Many Wall Tie replacement contractors come and go usually due to poor workmanship and incompetence so always use a reputable company.
