Why choose us

Waterproofing done properly the first time

Most wet area failures are not a product problem. They come from rushed prep, thin coverage and unchecked details. Here is how the HydroForce approach differs.

Other operators

  • Single rushed coat

    One thin pass applied over dusty substrate, then tiled the same day before the membrane has properly cured.

  • Details left exposed

    Corners, penetrations and floor to wall junctions skipped, which is exactly where leaks start showing up.

  • No paperwork

    No flood test, no photo record and no compliance certificate, leaving you unprotected at handover or resale.

With HydroForce

  • Full system build up

    Substrate prep, primer, bond breakers and two measured membrane coats applied at the correct wet film thickness.

  • Every junction reinforced

    Bandage tape to corners and hobs, collars to every penetration, and fall checked to waste before we sign off.

  • Documented and certified

    24 hour flood test, stage photos and a signed compliance certificate issued with your 7 year warranty.

How it works

A three step process that keeps your build on schedule

Step 01

Site inspection and fixed quote

We measure the wet area, check substrate condition, falls and drainage, then send a written fixed price scope within 24 hours. No guesswork over the phone and no surprise variations later.

Step 02

Prep, prime and membrane

Surfaces are ground back, vacuumed and primed. We install bond breakers, bandage every junction, collar the penetrations, then apply two measured membrane coats at full specified thickness.

FAQ

Answers to the questions we hear most

How long does bathroom waterproofing take?

A standard bathroom takes two visits over roughly three days. Day one covers prep, priming and the first coat, day two is the second coat, then we flood test for 24 hours before releasing the area to your tiler.

Do you provide a compliance certificate?

Yes. Every completed wet area comes with an AS 3740 compliance certificate, a photo record of each stage and your signed 7 year workmanship warranty, all emailed on the day of completion.

Can you fix a leaking shower without removing all the tiles?

Often, yes. We inspect first to identify whether the failure is at the grout, the silicone, the waste or the membrane itself. Where the membrane is intact we can seal from above with minimal demolition. If the membrane has failed, we will tell you straight and quote a full rebuild.

Do you work with builders and body corporates?

Regularly. We run multi unit programs for residential builders, strata managers and commercial fitout contractors, including staged scheduling, site inductions and consolidated progress reporting across a whole block.

Which suburbs do you cover?

All of Brisbane and the Gold Coast, plus Ipswich, Logan, Redlands, Moreton Bay, the Sunshine Coast and Toowoomba. Projects outside these areas are considered case by case, so please ask.

How much does waterproofing cost?

Pricing depends on the wet area size, substrate type, number of penetrations and access. We inspect on site and issue a fixed written quote within 24 hours so there is nothing left open to interpretation.
