Balcony & Waterproofing Compliance Canberra

Leaking balconies are the most common defect in Canberra strata buildings, and a surface reseal will not fix a membrane that has failed beneath the tiles. Remicon tests to find the entry point, removes the finish, corrects falls and detailing, installs a compliant membrane system and reinstates tiling, hobs, thresholds and balustrades as a single licensed contractor.

Leaking balconies are the single most common defect Remicon is called to in Canberra strata buildings. Water tracks under the tiles, through the membrane termination or the hob, into the slab, and appears as a stained ceiling in the unit below, a spalling soffit in the car park or blistered render on the façade. By the time it is visible, the membrane failed months ago.

Remicon rectifies waterproofing failures on balconies, podiums, planter boxes, wet areas and basements as a licensed builder. We test to find the entry point, strip back to sound substrate, install a membrane system compliant with AS 4654 and the National Construction Code, and reinstate tiling, hobs, thresholds, balustrades and finishes. One contractor, start to finish, photo-documented at every stage.

Waterproofing in Canberra: the difference between a reseal and a remediation

Search results for waterproofing in Canberra are full of shower reseal and regrout services. Those products have a place in a single bathroom. They are not a solution for a common property balcony over another owner's ceiling.

  • A surface seal over failed grout does not address a membrane that has lost adhesion or a termination that was never dressed correctly
  • An owners corporation that pays for a cosmetic fix carries the liability for the next leak
  • Remedial waterproofing means removing the finish, exposing the substrate, correcting the falls and detailing, installing a certified system and reinstating the finish. It costs more once and less over the life of the building

Canberra-specific waterproofing failures

  • Freeze-thaw movement at tile beds and hobs shearing membranes at the change of plane
  • Sealant joints at door thresholds hardening and cracking in winter, then flooding in spring storms
  • Balustrade posts core-drilled through the membrane on many 2000s builds, with no flashing at the penetration
  • Undersized balcony outlets and no overflow, so a blocked drain becomes a flooded slab

Waterproofing compliance and documentation for ACT strata

  • Membrane systems installed to manufacturer specification by licensed waterproofers, with warranty documentation issued to the owners corporation
  • Photographs at strip-out, substrate preparation, membrane application, flood test and completion
  • Reports formatted for strata records, insurer requirements and builder warranty claims

Frequently asked questions

Who is responsible for a leaking balcony in an ACT unit? In most Class A units plans the waterproofing membrane and structure are common property, so the owners corporation is responsible. The tiles and finishes may be the owner's. We document the failure so the committee can make that call with evidence.

Can you fix a balcony leak without removing the tiles? Rarely, and we will tell you if it is one of those cases. Most balcony leaks require the finish to come up because the membrane sits beneath it.

How long does a balcony remediation take? A single balcony typically takes one to two weeks including curing and reinstatement. Multi-balcony programs are staged across the building.

Do you provide a warranty? Yes. Membrane systems carry manufacturer and applicator warranties, and Remicon warrants the workmanship as the licensed builder.
