Wall Tie Replacement in Sydney, The Central Coast and Newcastle


The Problem: Corroded Wall Ties

The most common need to replace wall ties is from corrosion.

This is due to the fact that the original cavity wall ties would have been made from galvanised mild steel.

Over time the protective galvanising coating on the ties breaks down and allows the base metal to corrode.

The ties purpose is to provide lateral support between either the internal brickwork or timber frame, and the external brickwork/stone. If the tie corrodes it becomes weak and eventually the tie won’t be doing its intended job. This can lead to a very dangerous hazard where the external masonry can collapse!

How can you tell if your wall ties need replacing? This is often evident when you see the external walls start to bow or lean outwards and away from the main structure of the house. You may also start to see cracks appear in the brickwork.

Through our many years of experience we can tell from the types of bricks in a wall and know the most suitable approach for the repairs required. We can use an alternative tie installation method if the bricks are too soft for the conventional method, which means they are bonded with resin.

Testing the ties to make sure they are installed correctly is paramount, especially on larger jobs such as entire wall, side of a house or even an entire house. This involves the use of a load test unit being fixed over the end of a wall tie and then a load being applied. This tests that the ties are doing there intended job and will hold fast.

The house shown below was a new build property near Newcastle. The builders had used the incorrect duty of cavity ties because they were in close proximity to the ocean, a marine environment and as such they required an appropriate tie to be installed. The house was a timber framed brick veneer construction. The scaffolding had all been removed and so we had to install the ties from the inside. The builders opted to remove all the plasterboard from the timber frame of the walls. We installed the ties through the timber stud and across the cavity in to the back of the bricks. The work was completed in two days installing 900 replacement wall ties.
