What we do
Wet area waterproofing for homes and commercial sites
Every job is measured, specified and applied by our own licensed team — we do not subcontract membrane work. That is how we can guarantee it for seven years.
Shower Waterproofing
Walk-in, hobless and step-down showers sealed to full wall height where the design requires it.
- Screed and fall checks before membrane
- Puddle flange and waste detailing
- Flood test before tiling
Laundry Waterproofing
Tub, trough and washing machine zones protected against slow leaks that rot subfloors.
- Perimeter and splash-zone coverage
- Timber and sheet flooring prep
- Same-day turnaround on small rooms
Commercial Waterproofing
Amenities blocks, plant rooms, kitchens, balconies and podium decks for builders and body corporates.
- Staged works around trades
- ITPs, photos and sign-off packs
- After-hours access available
Leak Detection & Repair
Find the source before you demolish. Moisture mapping, flood testing and targeted rectification.
- Thermal and moisture meter testing
- Written diagnosis and scope
- Repairs from re-grout to full re-seal
Our process
Five steps from first call to compliance certificate
01
Site assessment
We inspect the wet area or read your plans, check substrate, falls and drainage, then confirm the right membrane system.
02
Fixed written quote
You receive a fixed price with the products specified, the standard applied and a firm install window — no day-rate surprises.
03
Preparation & priming
Substrates are cleaned, gap-filled and primed. Bond breakers, angle fillets and flange details go in before any membrane.
04
Membrane application
Two-coat systems applied at the correct wet film thickness, with reinforcing fabric at every junction and penetration.
05
Testing & certification
Flood test where required, photo record of every coat, then your AS 3740 compliance certificate and 7 year warranty.
Why HydroForce
Builders keep us on the schedule because we turn up
Waterproofing is a two-hour trade with a twenty-year consequence. A missed fillet at a hob, a thin second coat behind a niche, or tiling over a membrane before it cures — any one of them ends in a rectification claim and a stripped-out bathroom.
We built HydroForce around the boring details that prevent that: documented substrate checks, measured wet film thickness, photo records of every coat, and flood testing before tilers arrive. Our clients get a clean handover pack, not a verbal assurance.
- Same crew from quote to sign-off — no unfamiliar subbies
- Membranes selected for the substrate, not for the price list
- Programme-aware scheduling for multi-unit and commercial builds
- Straight answers on what is and is not covered by warranty

Client feedback
What clients say
“We had a shower leaking into the hallway wall for months and two other trades guessed at the cause. HydroForce moisture-mapped it, found a failed waste flange and had the whole shower re-sealed in three days. No smell, no stains since.”
Danielle R. — Bulimba, Brisbane
“They waterproof roughly forty of our townhouse bathrooms a year. Documentation is spotless, they hit the programme dates, and certifiers never query the work. That is worth more to us than a cheaper square metre rate.”
Marcus T. — Site Manager, Logan
“Renovated a 1960s Gold Coast unit with a step-down shower and awkward falls. They rebuilt the screed, sealed to full height and flood-tested it in front of me. Tiler said it was the neatest membrane he'd worked on.”
Peter H. — Mermaid Beach, Gold Coast
