A smooth process doesn’t always mean it’s a basic process, and the longer you put off a fix, the larger the problem is likely to be. When we discovered concrete spalling in a Rose Bay apartment block, we performed a full diagnostic, created a solution design and implemented a permanent waterproofing plan.
We thought we’d take you through one element of the repair process for the Rose Bay project to illustrate why comprehensive waterproofing solutions are essential to maintain and protect your strata property or luxury home… and why delaying treatment – or taking shortcuts – should never be an option.
The owner of the Rose Bay apartment block contacted Danrae Group after discovering a damaged ceiling. Our first step is to perform a full diagnostic, and what we found was extensive concrete spalling and potentially concrete cancer.
Concrete spalling and concrete cancer are consecutive stages of the same issue, and they occur when water or air seeps into concrete and affects the reinforcing steel that supports concrete structures. It causes the steel to rust and expand, cracking the surrounding concrete and letting even more water and air in – which accelerates the damage.
The treatment process may involve removing the affected concrete, identifying the extent of damaged steel, cleaning or replacing the steel, building up the missing concrete area with primers and other materials, adding a protective coating – and then laying a waterproofing membrane. For this project we used Sika products.
When people find a large leak, they generally seek immediate help. Unfortunately, other signs of a problem don’t always trigger action. Bubbling paint, rust stains and ceiling cracks may indicate concrete spalling. If left untreated it will develop into concrete cancer which can involve a much larger – and costlier – fix.
According to Ron Caruana, Founder and Project Manager with Danrae Group, knowing Danrae Group can fix any issue doesn’t mean you should leave it. “People do tend to ignore the warning signs. It’s common for many people to contact us only after it’s become a much bigger issue.”
