Tile Removal & Membrane Replacement in Brisbane

What balcony waterproofing in Brisbane actually involves

The sequence matters more than the products. Tiles and bedding come off, the slab is checked for cracks and for the fall it actually has rather than the one it was meant to have, upstands and the drain outlet are formed properly, and the membrane is dressed up the walls and into the drain flange before a single tile returns. A membrane that stops at the floor is a membrane with an edge for water to walk around.

The order the work goes in

Two of the four Brisbane operators walked in September 2026 sell tiling, tile removal and regrouting as named services alongside waterproofing, which reflects how the two trades overlap on this work. The page-one result set includes an operator whose own title describes it as a licensed waterproofer and tiler.

In Queensland this is the point where the paperwork becomes real. QBCC requires a waterproofing certificate — Form 43 or Form 12 depending on the circumstance — once waterproofing work exceeds $3,300, and a strip-and-rebuild will almost always cross that line. Form 43 is the Aspect Certificate issued by the licensed contractor to the building certifier. It is worth confirming in writing that your quote includes it.

Tile Removal & Membrane Replacement in Brisbane — common questions

How do I know whether I need a reseal or a full replacement?

A reseal addresses a breach in a membrane that is otherwise sound. A replacement is for a membrane that has aged out across the whole balcony. Moisture mapping distinguishes them: localised moisture points to a repair, moisture across the whole floor points to replacement.

Will I get a certificate for the work?

You should, once the work exceeds $3,300. QBCC requires a waterproofing certificate at that point — Form 43 or Form 12 depending on the circumstance — issued by the licensed contractor to the building certifier.

Can the existing tiles be reused?

Rarely. Tiles lifted off a bonded bed usually break or come away with mortar attached, and matching an older tile is often harder than replacing the floor. Assume new tiles and treat salvage as a bonus.
