Stop courtyard leaks before they drain your budget
Property managers and owners: Don't let courtyard water leaks turn into serious damage and costly repairs.
Why do courtyards leak?
Courtyard leaks happen more often than you’d think in Melbourne buildings. The good news? Catching them early saves you from major headaches and expensive repairs down the track.
Substandard construction
When courtyards aren't built properly - think flat surfaces with not enough fall to the drain waste - water has nowhere to go. This standing water constantly stresses the waterproofing membrane, causing it to break down faster.
Missing or faulty waterproofing
Think of waterproofing membranes as your courtyard's raincoat—they stop water getting through to the structure underneath. Too many courtyards are built with poor quality waterproofing membranes, badly installed, or sometimes none at all.
Age and weather taking their toll
Even the best-built courtyards can't fight Mother Nature forever. Years of rain, blazing sun, and temperature swings cause materials to expand and contract until they eventually start to fail.
Buildings that move and shift
All buildings settle and move slightly over time—it's completely normal. But this movement can put stress on seals and joints, creating small gaps where water can seep in.
Courtyard waterproofing in Melbourne can last 10-15 years with regular maintenance, though this can vary from 5-25 years depending on the membrane type and installation quality—and since courtyards often have car parks below, proper waterproofing is crucial to prevent asset damage.
Why you should care
Ignoring a leaking courtyard in your Melbourne commercial or apartment building isn't just a maintenance issue—it's a financial and legal risk. Here's what you're really facing when you delay waterproofing repairs.
Your building's value is at stake
Water damage doesn't just affect surfaces—it attacks the bones of your building. Concrete starts to crack, steel reinforcement rusts, and wooden supports weaken. This isn't just about repair costs; it's about your property's market value.
Courtyard leaks = costly property damage
When water leaks from shared courtyards into units, you're facing serious damage to flooring, walls, and residents' belongings. What starts as a minor drainage issue quickly becomes major repair costs.
Insurance headaches and liability claims
Picture this: your courtyard leaks into the basement car park, damaging cars and belongings. Now you're dealing with insurance claims, potential lawsuits, and premium increases.
Waterproofing problems get expensive fast
A small leak can quickly turn into a big problem. As water spreads, it damages more parts of the building — and the repair costs for property owners keep rising.
Spot the warning signs
Spotting courtyard waterproofing issues early can save your building from major damage, expensive repairs, special levies — and unhappy residents. These are some red flags to look out for.
Visible leaks below the courtyard: We see this often in Melbourne's commercial and apartment buildings: Water dripping into basements, car parks, or storage rooms, with drip trays hastily installed to mask the problem. This points to a serious waterproofing breakdown that needs urgent repair.
Soft or squelchy tiles: Feeling water movement or a spongy sensation underfoot when walking on courtyard tiles usually means water has seeped beneath the surface. This is a strong indicator of waterproofing failure.
White salt stains (efflorescence): Chalky white deposits on concrete or walls signal water movement through the structure. As the water evaporates, it leaves behind salts — a sign of waterproofing failure.
Pooling water after rain: If water sits on the courtyard for hours after rain, it’s a sign of poor drainage or an inadequate slope. This standing water can find its way through even small cracks, causing leaks and long-term damage.
Additional signs to watch for: Damage to vehicles or stored belongings in basement areas, moisture readings above 15%, and rust stains from exposed steel reinforcement. Look for these signs to prevent expense repairs down the line.

Waterproofing system installation
The membrane and related waterproofing layers are installed strictly following Australian Waterproofing Standards. We document every step with photos of critical details and installation. If needed, we apply a screed layer to create a proper fall (minimum 1:100) for effective water drainage.

Finishings
Whether its tiles or pods and pavers, the final surface is installed carefully to maintain the waterproofing integrity beneath, delivering both beauty and functionality.
