Rising Damp Perth assesses damp in North Perth, WA 6006, and we meter the wall before we quote.
North Perth's workers' cottages and California bungalows sit on the sand ridge north of the city, and the first thing to check here is levels rather than the water table. Paths, driveways and concrete aprons have been poured against the walls over decades, each one a little higher than the last, until the damp course is buried and bridged. If that is the cause, it is one of the more fixable versions of the problem, which is worth knowing before anyone quotes you for an injected course you may not need.
On the sand ridges water normally moves down and away, so damp here is more likely to be about something interrupting that rather than about the water table. A slab, a paved area, a compacted layer of fill or a buried footing can all hold water against a wall that would otherwise have drained. That makes the diagnosis a question of what has been built, and when — which is answerable, and worth answering before any treatment is quoted.
Also relevant to North Perth, and written once for every suburb it affects: ground raised past the damp course.
| Ground level within 250 m | 27 to 43 m above sea level (approx.) |
|---|---|
| Ground level at the centre | about 43 m |
| Indian Ocean coast (salt air) | about 9.6 km from the centre, straight line |
| Nearest river | Swan River, about 2.8 km from the centre, straight line |
| Perth CBD | about 2.4 km, straight line |
| Streets inside the suburb | Fitzgerald Street, Vincent Street, Walcott Street and Scarborough Beach Road |
| Parks and reserves | Charles Veryard Reserve, Beatty Park and Kyilla Park |
North Perth is 2.8 km from the Swan River and 9.6 km from the coast, so salt in the plaster most likely came up from the ground, not off the wind. The detail above names the likelier suspect: a path, driveway or apron poured against the wall above the damp course. A level check at the base of each wall comes before any talk of injection.
The six signs are on the inspection page, the order of the work on how it works, prices on the cost page and the measuring method on the about page.
