How we fix it
Taken back to the slab and rebuilt
Patching tiles and re-grouting won't stop a failed membrane. We rebuild the whole system.

Strip-out & prep
Old tiles and failed membrane removed back to a sound slab.

Screed to falls
Falls corrected so water drains to the waste, not the walls.

New membrane
A proven waterproofing system installed and detailed at every edge.

Tiled & sealed
Tiles relaid, grouted and sealed. Documented and warranted.

FAQ
Leaking balcony repairs questions
Straight answers for strata managers, committees and builders in Brisbane.
Can't you just re-grout or re-seal the tiles?
Grout and sealant won't stop water once the membrane under the tiles has failed. That's why patch repairs keep failing. We rebuild the system from the slab up.
Do you do the tiling as well?
Yes. Our own crew strips out, screeds, waterproofs and relays the tiles, so one contractor is responsible for the whole balcony.
Who do you do balcony work for?
Body corporates, strata and building managers, and builders. We focus on multi-unit buildings rather than one-off patch jobs.
Are you licensed and insured?
Yes. Hydro-Tec is licensed and insured for remedial work.
