Balcony Waterproofing in Perth

Why Balconies Leak and Why You Shouldn’t Ignore It

Balconies aren’t like other parts of the house. They’re exposed 24/7 to Perth’s weather. Blazing summer heat, heavy winter rains, constant foot traffic — all of it slowly eats away at grout, screeds, and waterproofing layers. What starts as something small, a hairline crack, chalky white residue on tiles (efflorescence), or water pooling after rain, can turn into:

• Damp walls and mould creeping indoors
• Drummy, loose, or cracked tiles
• Water stains on ceilings below
• Costly structural repairs down the track

Water is sneaky. Once it gets in, it spreads. That’s why a quick “patch job” rarely works. You need the cause fixed properly and that’s where a true balcony waterproofing specialist makes all the difference.

Our Proven Steps for Concrete Balcony Waterproofing in Perth

Concrete balconies need careful treatment: concrete is permeable, moves with temperature, and often contains salts that can cause efflorescence and tile adhesion issues. Our approach for concrete balcony waterproofing typically includes:

1. Full inspection and moisture mapping to find the source of ingress.
2. Removal of loose tiles or coatings where necessary, then structural repairs to cracked or delaminated screeds.
3. Substrate preparation: cleaning, crack stitching, and priming to ensure the membrane bonds correctly.
4. Application of a certified waterproofing system — liquid-applied membranes, cementitious systems for under-tile work or specialist sheet membranes where required.
5. Attention to terminations, flashings and drainage — the weak points in many balcony failures.
6. Re-tiling or protective surfacing and a final water test to confirm the system is watertight.
