Waterproofing Inspections on the Sunshine Coast
In the humid Sunshine Coast climate, where moisture is a constant, the waterproofing inspection is one of the most consequential stages of a new build. Booked after the membranes are applied but before tiling, it confirms the wet areas are sealed correctly. From Little Mountain and Meridan Plains to Aura, our builder-inspectors check the shower, bathroom, laundry and balcony membranes against AS 3740, including coverage at wall and floor junctions, upturns at hobs and doorways, treatment of penetrations and the falls to the floor waste. We confirm the shower drains at a gradient of at least about 1:80 and that bond breakers and primers were used where required. Tiling seals the membrane for good, so this check, while everything is still exposed, is one of the highest-value of the build.

Why a waterproofing inspection matters in Sunshine Coast
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 Sunshine Coast waterproofing stage we commonly check membrane coverage 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 and waste penetrations, and bond breakers at junctions. In the humid coastal climate we give balcony and external wet-area falls and ponding particular attention.
Local conditions in Sunshine Coast
Sunshine Coast new builds centre on the Aura (Caloundra West), Palmview, Sippy Downs, Little Mountain and Meridan Plains growth areas. The coastal climate — wind-driven rain and high humidity — makes waterproofing, roof and cladding details especially important, and many lots are on engineered fill. We inspect new builds only across the coast and send the photo report the same day, referenced to the NCC, Australian Standards and the QBCC 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 — Sunshine Coast
Why is waterproofing so important on the Sunshine Coast?
The humid coastal climate makes moisture control critical, so correct wet-area membranes, falls and balcony waterproofing are especially important here.
When is the waterproofing inspection carried out?
After the membrane is applied and cured but before tiling begins, so the full membrane can be inspected while it is still exposed.
What shower fall do you check for?
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.
