Balcony Waterproofing

Balcony Waterproofing: What You Need to Know

It’s raining again. Your sopping, slippery balcony has transformed an average downpour into a long-running nightmare – when it rains, it pools; when it pools, it crumbles, and when it crumbles, the sealant goes to hell and doesn’t even mention the joints. When you first moved in, the condition report wasn’t too bad – a chip here, a crack there, small stuff. And today? Leaking balcony tiles. Mould, decay and the sickening stench of inner dampness lingers despite your best efforts. Your balcony waterproofing membrane is virtually non-existent.

The good news? Some balcony waterproofing can save you grief, money and damage caused by leaks. But what do you look for? Where do you start? Megasealed have you covered.

Australians love their renovation projects. We’re certainly a resourceful lot. While the Megasealed team embrace the DIY philosophy, some projects shouldn’t be attempted lightly – one of them being waterproofing your balcony floor. One small mistake may not seem like a big deal now, but waterproofing issues don’t crop up straight away and are often invisible to the untrained eye. A trained Megasealed technician will apply the latest balcony waterproofing products to ensure stringent balcony waterproofing standards are met from day dot. Meaning? You save coins in the long run.

Spotting the Slip-Up

Too often, builders neglect basic waterproofing standards and cut corners. Therefore their work is inherently flawed. That said, balcony damage is probably not your fault – especially if you’re renting. Homeowners may have inherited an already problematic balcony from the moment they signed the dotted line. When a builder slaps together a house or contributes to an apartment, they sometimes build the balcony first and place the door afterwards, installing the membrane as the last step. This is a serious floor/wall junction problem. Australian standards are supposed to stop this from happening, but a lack of design detail means the builder will fall back on old, incorrect practices. It’s not malicious; they don’t know any better.

What’s Your Angle?

While we’re down on the floor, take a look at your balcony – does it gently slope toward a central drain? Are the water barriers and grouting in good condition? If you answered no twice, you’re in trouble. If a balcony isn’t draining correctly, an extensive re-tile may be worth considering – sure, it’s expensive, but water ingress isn’t like a seasonal virus; it won’t pick up and leave once the rain stops.

Don’t Hold Back on Balcony Waterproofing

A waterproofing membrane is essential to keeping your outdoor area in prime condition – think of it as a raincoat for your balcony.
