Waterproofing Experts for Substandard Balconies in Northern Beaches Multi-Residential Buildings

Balcony leaks are one of the most common — and costly — defects in multi-residential buildings. If you live in or manage an apartment block on the Northern Beaches of Sydney, and your balconies are showing signs of water damage, it’s time to speak to qualified waterproofing experts.

At Plan A Builders, we specialise in balcony repairs, waterproofing, and compliance upgrades for strata buildings. We’ve worked across Narrabeen, Dee Why, Manly, Collaroy, and other Northern Beaches suburbs — helping unit owners restore the safety, value, and longevity of their homes.

🧱 Why Balcony Waterproofing Fails in Multi-Residential Buildings

Balconies are exposed to the full force of the coastal weather on the Northern Beaches — salt, sun, wind, and rain.

Common causes of balcony waterproofing failure include:

• Poor original construction or missing membranes

• Cracked tiles and degraded grout

• Inadequate drainage systems

• Movement in concrete slabs

• Water pooling and leaking into internal ceilings or walls

These issues often affect multiple apartments in a block — and if left untreated, they can become structural safety risks.

🧰 What a Waterproofing Expert Does (and Why You Need One)

Waterproofing experts aren’t just people who apply membranes — they are trained to:

• Inspect balconies for signs of failure (surface and structural)

• Identify underlying causes (like drainage faults or slab cracks)

• Recommend compliant waterproofing systems

• Work alongside engineers, certifiers, and strata managers

• Provide documentation required for insurance and NSW Planning Portal submissions

At Plan A Builders, we take a comprehensive approach — integrating both building knowledge and compliance expertise to deliver long-term results.

💧 Signs You Need Waterproofing Repairs

Don’t ignore these common signs of balcony failure:

• Soft or spongey floor tiles

• Efflorescence (white salt deposits)

• Leaks through ceilings below

• Visible cracking in corners or joints

• Rust spots near balustrade posts

• Mould and musty smells indoors

If you spot any of these issues, contact waterproofing experts immediately to avoid further damage.

🔍 Do I Need Council Approval?

If your balcony repairs involve:

• Structural slab work

• Balustrade upgrades

• Changes to drainage or facade appearance

You may need approval through the NSW Planning Portal, either via a Complying Development Certificate (CDC) or a Development Application (DA). We’ll guide you through that process and provide all supporting documents.

🛠️ Example: Waterproofing Remediation – Dee Why, NSW

A 16-unit block in Dee Why was experiencing water penetration through multiple balconies. We:

• Conducted a detailed assessment of each unit

• Removed failed tiles, membranes, and screed

• Installed a compliant multi-layer waterproofing system

• Upgraded drainage to meet current standards

• Re-tiled with slip-rated balcony surfaces

The result: a watertight, compliant, and visually appealing balcony system — with full documentation for strata records.
