Waterproofing your balconies

Our balconies are where we sit, relax and soak in the outdoors. They are an important aspect of our homes and lifestyles, especially in a busy city like Sydney.

Because balconies are on the exterior of our buildings, they are exposed to all the harsh weather elements Australia has to offer—from the blistering summer heat to cold rainy days.

When using any aspect of our homes, we want peace of mind regarding their stability and our safety. Concrete balconies, which are the most common, can have water soak into them easily. This can cause cracks and erosion that should be fixed immediately.

And balcony repairs are a hassle! If an accident does occur due to water damage, it can be expensive and emotionally damaging. Having balcony membrane waterproofing is vital for your home and your personal protection.

There are two main balcony-waterproofing methods: sheet & torch on and liquid membrane waterproofing. And determining which one is best suited depends on the size and accessibility of the structure.

We are Sydney waterproofers that offer solutions for you—and we can discuss the best match for your home.

Sheet & torch on membrane waterproofing

For a solution that is suitable for larger balconies, go for sheet and torch on membrane waterproofing. This method is highly effective and long-lasting.

Our sheet membranes are made up of a mixture of bitumen and polymers which will be layered on your balcony. It is then torched with a flame to bond the waterproofing substance to the structure.

Sheet and torch on membrane waterproofing

It takes expert waterproofers to correctly apply sheet and torch membranes. Otherwise, the bonding may not be right. That defeats the whole purpose of investing in waterproofing.

This method is good for extremely cold weather and has a high tensile strength, making it a potential solution for your balcony.

Liquid membrane waterproofing

For more confined or smaller balconies, then applying liquid membrane is an effective method. This is a liquid solution that bonds to form a waterproof rubbery coating.

Because of its texture and form, it can adapt to many shapes. This makes it effective for balconies with tighter corners and intricate designs, especially in areas where water may build up or create pockets.

Our seals are UV resistant, durable, flexible and breathable, so water stays out and your lifestyle isn’t hindered.

Liquid membrane waterproofing

Each balcony is different. Consulting with an expert team is best when deciding which method to go with.
