Orion Centre in Campsie – Wall Stabilisation

The walls in this beautiful Art Deco building were surveyed for a period of a year to discover the amount of displacement caused by settlement or rotation. Although the displacement was insignificant the stepping cracks in the walls had increased and some cracking at the damp course had appeared.

This displacement over the year indicated that the walls were moving probably due to lack of restraint. This fault occurs where the wall ties have corroded. It was decided to use Helifix Wall Ties and Crack Stitching bars to remediate the walls.

WHAT WE WON’T DO

Adjacent to our project at Campsie was a wall that had been “repaired”.  As it turns out the work was not only unsightly but ineffective. The brick courses were not stitched across the cracks and a movement joint possibly could have avoided future cracking.

Helitec Structural Services  are approved installers of the Helifix remedial masonry system. Our workmanship is guaranteed.
