Professional Balcony & Rooftop Waterproofing Across Sydney
Balconies and rooftops are constantly exposed to weather, temperature changes, and water runoff. Without correct waterproofing, these areas are one of the most common sources of leaks, concrete damage, and internal water ingress.
At Real Seal Solutions, we provide balcony and rooftop waterproofing in Sydney for builders, developers, and homeowners, delivering compliant systems designed for long-term performance.
Residential balconies
Apartment and strata balconies
Rooftop slabs and terraces
Exposed concrete areas
All work is completed using certified waterproofing membranes applied to suit site conditions and exposure levels.
Balcony Leak Repairs Sydney
In addition to new waterproofing works, we also provide balcony leak repairs where possible.
Depending on the condition of the existing system, we may be able to carry out targeted repairs rather than a full rebuild.
Each project is assessed individually to determine the most practical and reliable solution.
Our Waterproofing Process
A clear, compliant approach trusted by builders and homeowners across Sydney.
1. Inspect
We assess the area, substrate condition, junctions, and compliance requirements before any work begins.
2. Prepare
Surfaces are prepared correctly, with careful detailing of corners, penetrations, and critical waterproofing zones.
3. Waterproof
Certified waterproofing membranes are applied to Australian Standards using proven systems and materials.
4. Verify
Final checks are completed to ensure long-term protection before handover or tiling.
If you’re experiencing active water ingress, our balcony waterproofing Sydney specialists can assess and resolve the issue.
