Waterproofing in Hamilton

The Hamilton job we know best
Hamilton runs from the river flats up Hamilton Hill, and most of the work we see here is on a building that has had things added to it. A flat-roof addition off the back of a heritage Queenslander, a parapet on a rendered cottage that was never quite sealed right, a tiled deck over a habitable room, a roof flashing that has weathered into a slow drip the owner only notices through a stain on a bedroom ceiling.
The honest answer for a lot of Hamilton homes is that the original wet areas were built decades before AS 3740 existed in its current form, and the additions were often built before AS 4654 was even named. The job is bringing them up to the current Standard quietly, without changing the character of the home.
Where waterproofing fails on an older Hamilton home
- Flat-roof additions and parapets. A flat-roof room added off the back of a Queenslander is the most common silent leak in Hamilton. The parapet upstand, the flashings into the older roof, and the fall on the flat are all places where a forty-year-old membrane has long given up. We rework them to AS 4654 in a liquid system rated for exposure, with the upturns and the drainage detailed properly.
- Character wet areas in renovation. A 1930s bathroom with a timber subfloor needs the floor primed, the upturns to height, bond breakers in the cove and the membrane to AS 3740. Done right inside an original footprint, with the certificate handed over so the renovation signs off without a fight.
- Roof flashings on a Queenslander. Older corrugated roofs on Hamilton Hill grow leaks at the chimneys, the box gutters and the wall flashings, not in the open run. We diagnose where the water is actually tracking first, then rework the flashing and the surrounding membrane to suit, rather than seal the spot under the stain.

Remedial Leak Repair
Leak diagnosed first, then a shower re-seal or membrane make-good, so we fix the cause once rather than seal over it and watch it leak again.

Planter Box & Water Feature Waterproofing
Planter boxes, ponds and water features tanked and detailed so constant standing water and root pressure do not find their way into the structure.

Before 
After What Brisbane owners say.
“Three quotes, and Sealline was the only one that traced where the water was actually coming from before quoting. The stain was nowhere near the leak. They stripped the ensuite, re-membraned it to AS 3740, flood-tested it and gave us the certificate. Dry for a year now.”
“Our balcony was bubbling and the ceiling below was staining. Priya found the falls were running back toward the house. They corrected the fall, re-membraned to AS 4654 and detailed the drain properly. The number on the quote was named by the square metre, no vague lump sum.”
