What we do
Waterproofing specialists for every wet area, above and below ground
U.P Waterproofing is a Hervey Bay business led by Umberto Polizzi, a seasoned specialist with more than 18 years of hands-on experience. He waterproofs new residential builds, renovations and large commercial projects right across the Fraser Coast.
What we do
One goal on every job
From the shower in a brand-new home to the roof deck of a commercial building: stop water getting where it shouldn't, and keep it out for the life of the building.
Why it matters
The leak you can't see is the most expensive kind
Water works slowly and quietly. By the time you notice a stain, a lifting tile or a musty smell, it has usually been soaking into timber, plaster and concrete for months.
Prevents costly damage
Failed membranes mean rotting frames, drummy tiles, mould and structural repairs. Doing it right first costs a fraction of tearing out a finished bathroom.
Why it matters
Protects your property value
Salt air, humidity and summer storms are hard on coastal buildings. Sound waterproofing protects what your home or investment is worth.
Meets Australian Standards
Internal wet areas to AS 3740 and external above-ground membranes to AS 4654.2, so your project is compliant and ready for sign-off.
Why it matters
Gives you peace of mind
18+ years of hands-on experience, so you can tile, paint and move on without wondering what's happening underneath.
New builds to complex renovations
A fresh slab or a tricky renovation over existing surfaces: the system is matched to the job.
How we help you
Waterproofing services in Hervey Bay
How we help you
Balcony & roof waterproofing
Balconies, decks, podiums and flat or low-pitch roofs sealed for UV, ponding water and coastal weather, to AS 4654.2. The usual fix for water dripping into the room below.
Basements & retaining walls
Below-ground walls hold back soil and groundwater. Waterproofing keeps moisture on the outside, protecting the structure and the space behind it.
How we help you
Commercial external waterproofing
Podium decks, planter boxes, car park slabs and external envelopes for commercial and multi-residential builds, coordinated with the builder's program.
New construction & renovations
For builders, a reliable waterproofer who fits the schedule. For renovators, a careful check of existing surfaces before any membrane goes down.
Why trust U.P Waterproofing
The one trade you never want to think about twice
Umberto Polizzi brings a high standard of workmanship, quality materials and close attention to detail to every project, from a single ensuite to a multi-level commercial site.

What clients say
Dry bathrooms, happy clients
“Our shower had been leaking into the hallway for years. Umberto stripped it back, waterproofed it properly and our tiler said it was the neatest membrane he'd seen. Not a drop since.”
What clients say
“As a builder I need trades who turn up when they say they will. U.P Waterproofing has done the wet areas on our recent homes and the work has been spot on every time.”
“Our upstairs balcony leaked into the garage every time it rained. Umberto explained exactly what had failed, gave us a fair quote and sorted it quickly.”
What clients say
“Professional from quote to finish. Clear pricing, a tidy site, and he took the time to explain the standards and why they matter.”
The layer you'll never see
Once the tiles go down, this is what keeps you dry
That blue coat is the waterproofing membrane. It sits under every tile, along every joint and around every drain. Once the bathroom is finished you'll never see it again, which is exactly why it has to be done properly.
