Rising damp in Hyde Park, South Australia

Rising Damp Adelaide arranges on-site salt damp assessments across Hyde Park and the rest of Adelaide. Someone meters the wall at several heights, compares the ground outside against the floor inside, and puts the cause in writing before anyone quotes a repair.

Hyde Park housing and salt damp

The sandstone villas through Hyde Park fail differently from bluestone. Sandstone is porous, so it takes the water and the salt into the body of the stone rather than confining it to the joints. The result is fretting: the face of the block dishes, powders and drops away while the mortar stands proud of it. That is the expensive failure, because stone repair or indenting costs far more than repointing does. It is also the strongest argument for dealing with a damp problem early rather than watching it for another few summers.

What the ground does here

Two things shape every assessment in Hyde Park. The walls are sandstone and freestone villas, 1890s to 1915, which sets where the moisture and the salt actually travel. And the damp course is none, or long since failed, which sets whether this is a missing barrier, a broken one, or a bridged one.

None of this would matter nearly as much in a mild climate. Adelaide records about 540.6mm of rain across 82.0 days, then dries hard — a 3pm humidity near 36 per cent in February. Every one of those cycles deposits more salt inside the masonry.

Booking a Hyde Park assessment

There is no charge for the assessment and no obligation afterwards. What treatment costs depends on the material, the access and how much salt is already in the wall — the published ranges cover it.
