Waterproofing Inspections in Brisbane
The waterproofing inspection is booked once the wet-area membranes are applied but before any tiling starts, because tiles seal the membrane away for good. In Brisbane homes from Everton Park to the bayside suburbs, our builder-inspectors check the shower, bathroom, laundry and balcony membranes against AS 3740, including coverage at floor and wall junctions, upturns at hobs and doorways, treatment around penetrations and the falls to the waste. We confirm the shower floor drains at a minimum fall of about 1:80 and that bond breakers and primers have been used where required. Water damage is one of the most expensive and disruptive problems in a new home, so confirming the membrane is right before tiling is one of the highest-value checks in the whole build.

Why a waterproofing inspection matters in Brisbane
Waterproofing is the highest-consequence trade in the whole build — almost every leak a home ever has starts at a wet-area membrane, and once the tiles are on, a defect here means ripping them up to fix it.
At Brisbane waterproofing stage we commonly check membrane coverage and thickness to AS 3740, upturns at hobs, doorways and walls, falls to the floor waste with a shower gradient of at least 1:80, sealing around tap, waste and drain penetrations, and the use of bond breakers at junctions. Ponding or flat areas on balconies get particular attention.
Local conditions in Brisbane
Brisbane's new-build activity runs from the northern suburbs — Aspley, Bracken Ridge, Carseldine and the Fitzgibbon priority development area — out to the bayside east around Wynnum and Manly West. Much of it sits on reactive clay and some on filled or sloping lots, which makes the early slab and frame stages worth getting right. Our builder-inspectors cover the whole metro area and send a same-day photo report referenced to the NCC, the relevant Australian Standards and the QBCC Standards and Tolerances Guide.
What we check at the waterproofing stage
Before tiling, we check the wet-area membranes — the single most common source of future leaks (AS 3740):
Membrane (AS 3740)
- Membrane coverage to walls, floors and hobs/upturns
- Falls to the waste (shower floor ≥ 1:80)
- Penetrations, bond breakers and corner detailing
Preparation
- Substrate preparation and primer
- Shower screen and waste set-out
- Overflow and balcony/external wet-area detailing where applicable
Every item is photographed and referenced to the relevant Australian Standard, NCC clause or the QBCC Standards and Tolerances Guide, then delivered in a same-day digital report you can hand straight to your builder.

Waterproofing Inspection FAQs — Brisbane
When should waterproofing be inspected in a Brisbane build?
After the membrane is applied and cured but before tiling begins, so the full membrane can be seen and checked while it is still exposed.
Why is the waterproofing stage so important?
Membrane faults cause leaks that are very costly to fix once tiling is on. Checking falls, upturns and penetrations now is one of the highest-consequence stages.
What falls do you check in showers?
We confirm the shower floor falls to the waste at a minimum gradient of around 1:80, with correct upturns at hobs and doorways under AS 3740.
