Waterproofing & Leak Prevention

Waterproofing & leak prevention.

Tiles and grout aren't a waterproof barrier on their own. SEQ Tiling waterproofs bathrooms, showers, laundries, balconies and outdoor surfaces to the relevant Australian Standards before tiling — the membrane that actually protects your build from leaks and costly water damage.

Wet area waterproofing before tiling by SEQ Tiling
What's included

The part of the job you never see — and can't skip.

Waterproofing is the single most important stage of any wet area, and the most common cause of expensive damage when it's rushed. We treat it as core work: correct membranes, correct curing time, correct detailing, every time.

Waterproofing & Leak Prevention — questions

What clients ask us.

Why does a wet area need waterproofing before tiling?

Tiles and grout are not a waterproof barrier on their own — water passes through them over time. Waterproofing creates the membrane underneath that actually keeps moisture out of the building structure. Skipping or rushing it is one of the most common causes of leaks, damp and costly damage in a wet area.

Which areas do you waterproof?

We waterproof bathrooms, showers, ensuites, laundries, balconies, and outdoor and pool surfaces — any area exposed to water before it is tiled. As tilers we treat waterproofing and tiling as one job, so the membrane and the finished surface work together as they should.

Is your waterproofing compliant with Australian Standards?

Yes. All of our waterproofing is carried out to the relevant Australian Standards for wet areas. As a Building Services Authority licensed business, doing this part of the job correctly is non-negotiable — it protects the home and it protects our six-year workmanship guarantee.

How is waterproofing priced?

Waterproofing is usually quoted as part of the overall tiling job for a wet area, and the detail is set out in your written quote. If you need waterproofing assessed on its own — for example on an existing or problem area — we're happy to look at it and quote the work required.

Can you fix a wet area that's already leaking?

Yes. If a shower or wet area is leaking, the waterproofing has usually failed and the tiling above it needs to come up to fix it properly. We'll investigate the source, re-waterproof to the relevant standards and re-tile, so the area is genuinely sealed rather than patched.

How long does waterproofing take to cure?

Waterproofing membranes need time to cure before tiling can begin, and rushing that stage undermines the whole job. We build the correct curing time into the program and won't tile over a membrane until it's ready — it's a key part of getting a wet area right.

Is waterproofing guaranteed?

Yes. Waterproofing is covered by the same six-year workmanship guarantee as the rest of our work, and is carried out under our Building Services Authority licence. Done properly, it's what keeps a wet area sound for many years.
