Winter Is Coming — It’s Time To Waterproof Your Balcony

As the weather begins to cool down in Perth, it’s a good time to start preparing for the rainy season. That might sound a bit dramatic — we’re not expecting any monsoons — but poorly waterproofed area can lead to significant, costly damage in your property.

Whilst wet-areas, like bathrooms, are the obvious place to think of when we mention waterproofing, in winter, we want to consider balconies. This is especially true when it comes to older properties that have seen a bit of wear-and-tear. When it rains, improperly waterproofed areas can lead to expensive water penetration and leak issues such as flooding, concrete cancer, and rising damp.

What to look for

A water-damaged balcony usually occurs when the balcony hasn’t been properly waterproofed in the first place, or when the building is old and simply worn down. In either case, here’s what to look for:

  • Loose or cracked tiles.

  • Splitting, cracked, or peeling paint.

  • Discoloured or stained tiles and grout.

  • Mould.

  • A hollow sound underfoot.

  • Water pooling.

Can I DIY?

 

 

 

 

 

 

 

 

 

 

 

Although there are DIY waterproofing products on the market, we strongly advise against tackling such a foundational job alone. If waterproofing or protective coatings are incorrectly applied, you’ll end up having to redo it later, which will burn a hole in your pocket, fast.

 

For example, clear sealers applied to the surface of the floor quickly fail as they are non-flexible so develop micro-fine cracks as soon as there is thermal expansion and contraction in the substrate and let water through. Repairing the waterproof membrane directly over a leak is also not guaranteed to fix the issue as the staining or damage from a leak can often offset from the source of the leak, and warranties are not possible on these repairs.

 

Materials used in these types of jobs need to be selected specifically for the issues and certified along the way to make sure warranty conditions are met. It’s always best to engage a professional to ensure the job is done correctly the first time — it’ll be much faster, and save you money in the long run.

Don’t wait

If you’ve noticed any of the symptoms of a water-damaged balcony, don’t delay. The longer you wait to repair leaks and other water penetration, the more complex (and expensive) the job will be.
