In the images above you can see a property in Chatswood, NSW. Whilst undergoing major renovations it was obvious that something was wrong with the decorative mouldings above the windows. They were cracked and at the point of needing rehabilitation sooner rather than later. The architect overseeing the work for the owner builder asked us what could be done to repair the two bay windows. Helicrete consulted with the in house engineer, and in turn the UK engineer's from Helifix, who devised a repair method which would provide strength and stability to the masonry above the two windows. This was achieved by Helicrete utilising a combination of standard repair methods from Helifix.
Value of the lintel replacement work was circa $20,000
The most common need for lintel replacement is from corrosion. Similar for the need for cavity wall tie replacement, when either element has its protective coating damaged then corrosion can take place. This can result in the steel expanding from 7-12 it's sectional area. With most of Australia's populated regions being in close proximity to the coast this only exacerbates the corrosion to occur faster. As the embedded steel corrodes it begins lifting and cracking of masonry or concrete above and below.
When this damage occurs to concrete it is often referred to as concrete cancer/concrete spalling.
Lintel replacement and lintel repairs.
We can remove the existing lintel and install a new one, with flashings above if required. We will where possible save as many of the original bricks and re-use them, and where necessary find a match for any that are damaged to give as close to an invisible repair as possible.
