Coorparoo, QLD
Coorparoo: 1970s blocks at the age when carbonation can reach the steel.
Concrete Cancer Brisbane inspects and repairs concrete in Coorparoo, where the typical buildings are 1970s–80s walk-up units, and the written scope comes before any repair price.
Coorparoo's 1970s and 80s walk-ups are now at an age when carbonation can reach the reinforcement where cover is thin. That timing matters for a committee: buildings that have needed almost nothing structurally for forty years start presenting real remedial costs within a fairly narrow window, and sinking fund forecasts written before the first spall appeared can be well short. Getting a scope early, while the repair is still patching rather than replacement, is the cheapest version of this problem.
| Typical buildings | 1970s–80s walk-up units |
|---|---|
| Nearest Moreton Bay shore (salt air) | about 12.8 km (straight line) |
| Distance to the Brisbane River | about 2.4 km (straight line) |
| Ground height within 250 m | about 8–24 m above sea level |
| Brisbane CBD | about 4.4 km (straight line) |
| Main streets in the suburb | Cavendish Road, Stanley Street East, Chatsworth Road and Tiber Street |
| Parks in the suburb | Bath Street Park, Coorparoo Creek Park and Wembley Park |
Coorparoo's centre is 12.8 km from the bay and 2.4 km from the Brisbane River. At those distances, the mechanism to expect in a 1970s block is carbonation. Carbonation advances roughly with the square root of time, so it slows as it goes deeper, and a block with thin cover reaches the steel decades before one with more. That is the narrow window in the detail above. A cover survey on a sample of balconies gives the committee a forecast, not just a repair list.
Prices are on the cost page and the measuring method is on the about page. Nearest suburbs with a page here: Woolloongabba (about 3 km), Kangaroo Point (about 3 km), New Farm (about 3 km), Mount Gravatt (about 5 km).
The suburbs below cover the 1960s–80s walk-up belt and the bayside strip, where salt air can reach the steel faster.
Tell us what the concrete is doing. We will inspect it and give your committee a written scope and a quote it can actually vote on.
