Question: Concrete cancer has been found and remediated in one of our strata scheme’s three blocks. Should we check all units?
Our strata scheme has three blocks under the same strata title. We discovered concrete cancer in one block and it has now been remediated.
Should every unit be checked? How is that done? Owners will be reluctant. If more concrete cancer is found, the cost of remedial works could be colossal.
Answer: If concrete cancer is found in one part of a strata building, it is highly recommended to check all areas of similar design or construction.
It is highly recommended to check any areas of similar design or construction for signs of concrete cancer if it has been previously discovered elsewhere.
If it is the same strata property under the same title, it would have been the same builder who constructed the units, and likely the same trades used. Unfortunately, we do see a high volume of defects duplicated in strata schemes due to repeat installation issues. Therefore, it is always best practice to check.
A building consultant or engineer can undertake a visual assessment for telltale signs. If there are any suspicious areas, further investigation can be undertaken. It is possible that only minor works may be required (if any) in comparison to the work already undertaken. Owners should understand that detecting and addressing concrete cancer early can result in significant cost savings, as opposed to leaving it to further deteriorate.
