Hobart's Leading Waterproofing Company – Protect Your Home from Water Damage
Keeping Hobart Homes Dry Since Day One
Look, living in Hobart means dealing with rain. Constant dampness. Humidity that creeps into everything. And water damage? It doesn’t announce itself with a big dramatic leak. It starts small – bit of mould in the corner, grout looking dodgy, tiles sounding hollow when you tap them.
Then one day you’re staring at a stain spreading across the ceiling downstairs, or you’re pulling up floorboards finding timber that’s rotted right through. That’s when people realise waterproofing isn’t something you mess around with in Tasmania.
We’re Hobart’s professional waterproofing company. Our licensed installers understand what this climate does to properties – the weatherboard homes in Battery Point, the older places in New Town that’ve never had proper waterproofing, the renovations in Kingston that need everything done to code. We work to Australian Standards AS 3740, provide proper certification, and use quality systems that hold up in Tasmanian conditions. Because doing waterproofing properly the first time? That’s a hell of a lot cheaper than fixing the damage when it fails.

What Professional Waterproofing Actually Means
Here’s the thing about waterproofing – most people don’t understand what it actually is until something goes wrong. They think grout’s gonna keep water out. Or they reckon a bit of silicone around the shower base will do the job. But proper waterproofing? That’s a membrane system installed underneath everything you can see, and it’s gotta comply with Australian Standards AS 3740-2021. The process starts with proper surface preparation – cleaning, repairing, priming – because if the membrane’s going onto a dodgy surface, it’s gonna fail.
Our licensed waterproofers install either sheet membrane or liquid membrane systems, depending on what the job needs. Every penetration gets sealed properly:
- Floor-to-wall junctions and corners detailed correctly
- Pipe work and drains sealed at every penetration point
- Shower recesses waterproofed to proper heights
- Substrate prepared before membrane installation
Everything comes with certification documentation for council and insurance. In Tasmania’s climate, cutting corners with waterproofing isn’t just risky – it’s guaranteeing problems down the track.
Common Waterproofing Problems We Fix in Hobart
Leaking showers are the biggest problem in older Hobart homes – no membrane underneath, water’s been getting through for years. Bathroom floor damage shows up as ceiling stains below, but the subfloor’s usually worse than what you can see. Deck deterioration happens when moisture gets into timber joists and bearers – rot spreads fast in damp conditions.
Balcony leaks drip into living areas below. Rising damp comes up through foundations in older homes without proper damp-proof courses. Mould growth from excessive moisture creates health hazards. Tile failure means water’s gotten underneath and broken down the adhesive. Timber rot in structural framing spreads through buildings. External wall penetration lets weather-driven rain through weatherboard cladding. Grout failure happens because people thought grout was waterproofing – it’s not.
Signs You Need Waterproofing Services
Water stains on ceilings below bathrooms mean moisture’s been getting through for a while already. That stain’s the visible part – the damage behind it’s usually worse. Musty odours tell you there’s hidden moisture somewhere, even if you can’t see it yet. Mould or mildew growth in bathrooms means too much moisture and possibly failed waterproofing.
Tiles lifting or sounding hollow when you tap them indicates water’s gotten underneath and broken down the adhesive. Grout cracking or crumbling away shows moisture is moving through joints. Paint peeling or bubbling on bathroom walls means moisture’s getting into the plasterboard behind. Damp patches appearing after rain or showers are classic signs of penetration.
Water pooling on balconies or decks instead of draining away properly indicates problems. Visible rot in timber structures means moisture’s been there long enough to break down the wood. Cold, damp feeling in rooms suggests moisture’s getting in through the walls.
Get onto these problems early. Tasmania’s climate makes water damage progress faster than drier places.
Waterproofing Systems and Methods We Use
Sheet membrane systems like Wolfin or Schluter come with pre-formed corners and penetration boots. You can actually see the membrane’s been installed correctly before the tiles go on. Best for complicated shower layouts and commercial applications where reliability’s critical. Liquid membrane systems are polyurethane or acrylic-based coatings that we brush or trowel on in multiple coats. They create seamless waterproof layers that work well for standard bathrooms. Cost-effective for straightforward layouts.
Combination systems use sheet membrane for floors where there’s the most water exposure, and liquid for walls. This optimises the strengths of both – durability where you need it, cost-effectiveness where that makes sense. Works particularly well in older homes with existing conditions.
Tanking systems are cement-based products for heavy-duty protection on basements, retaining walls, and external walls. They’re breathable and paintable. Drainage solutions like linear drains and sump pumps remove water before it becomes a problem. For balconies, decks, and basements, proper drainage makes the whole waterproofing system work long-term.
How We Handle Your Waterproofing Project
We start with a proper site inspection – come out and assess what’s actually going on, identify moisture issues, figure out what’s needed. No point quoting for work that won’t solve the problem. We use moisture meters and thermal imaging to detect hidden damage in wall cavities or under floors.
You get a detailed quote specifying exactly what materials we’re using and what standards we’re meeting. Then comes surface preparation – this is where most waterproofing fails. We clean, repair, and prime surfaces properly because the membrane’s only as good as what it’s sticking to.
Membrane installation follows manufacturer specifications exactly. Every pipe penetration, drain, fixture, and corner gets sealed correctly. Where applicable, we flood test before tiles go on. You get compliance certificates for council and insurance, plus documentation with photos, product data sheets, and warranty information. We tell you proper curing times and how to protect the membrane during subsequent work.
FAQ
Most frequent questions and answers
Because of our climate. High rainfall and constant dampness mean moisture’s always trying to get into buildings. Without proper waterproofing, you’re gonna get structural damage, timber rot, and mould growth. Prevention’s way cheaper than repair.
Quality installations done properly last ten to fifteen years or more. The lifespan depends on what materials were used, how well they were installed, and how much traffic and wear the area gets. Sheet membrane systems typically last longer than liquid systems.
Generally no. Tiles need to come off so we can install the membrane onto a properly prepared substrate. Trying to waterproof over tiles usually fails because you can’t get proper adhesion.
Grout is NOT waterproofing. Grout’s porous – water goes straight through it. The waterproofing membrane sits underneath the tiles and substrate. That’s what actually stops water penetration.
