Cavity Wall Tie Replacement

Cavity Wall Tie Replacement

Cavity Wall Tie Replacement is a cost-effective method to reinstate the structural integrity of your building. Helitec Structural Services replace corroded and failing wall ties with marine grade stainless steel helical ties.

Helitec are experts at replacing cavity wall ties. At Helitec we undertake the right cavity wall tie replacement for your building in Sydney and regional NSW. We use concealed non-disruptive installation techniques.

Thin Veneers, Hollow Blocks, Solid Multi-Leaf Masonry, Timer and Steel Framed Veneers, Stone and Concrete are all covered. Once your failing wall ties are replaced by Helitec you will never need to repair wall ties again, as they are manufactured using high quality marine grade 316 stainless steel material, which won’t corrode.

Our methods include dry fixing, using resins and bonding chemicals, mechanical reinforcements for seismic conditions, both new constructions and retro fitting older buildings.

Due to marine environments and low grades of materials used during construction, wall tie corrosion has become a common issue in established buildings. If left untreated the consequence can lead to the exterior masonry of the cavity collapsing. Wall tie replacement is a fast and cost-effective option available to eradicate the issue. The craftsmanship used during replacement of wall ties can be the difference between a building just being made stable or making it safe and enhancing its beauty. At Helitec we are dedicated to ensuring every building we work on looks great at the end of the job.

We ensure the brick cavity wall ties installation is of the highest quality by carrying out a stress test on each and every job we do to ensure the ties are going to do their intended job. A stress test report is issued to the building owner.

If the walls in your building:

  • Have movement
  • Are bowed or lean
  • Have falling Parapets
  • Falling floors
  • Have lateral movement between brick courses

Your walls may be failing, and in a worst-case scenario, they may collapse.
