Manly Waterproofing
Manly’s exposed coastline, high-density housing and elevated rainfall make professional waterproofing a necessity, not a luxury. Salt air accelerates material breakdown, while dense development and sloping blocks increase water pressure on structural components like retaining walls, basements and slab edges.
Proper waterproofing prevents internal damage, rising damp and costly long-term deterioration—especially in homes with underground levels or tiled balconies. Whether you're developing a duplex, renovating a coastal home or maintaining a heritage build, moisture control must be done right the first time. At Legend Waterproofing, we apply robust, code-compliant systems tailored for high-exposure settings. Every project is approached with a clear strategy, premium materials and experienced hands.

Frequently Asked Questions
Do coastal properties require more frequent waterproofing updates?
Yes—salt air, sand particles and extreme UV levels can shorten membrane life. Even premium systems may need inspection or touch-ups more regularly in coastal zones. Maintenance every few years ensures ongoing performance.
What’s the difference between positive and negative-side waterproofing?
Positive-side waterproofing is applied to the side exposed to water (e.g. outside of a wall), while negative-side is applied internally. In cases where external access is limited, negative-side treatments offer an alternative. However, positive-side solutions are usually more effective when possible.
Can waterproofing fix existing dampness or only prevent it?
Waterproofing can do both, depending on the source and severity of the issue. It can stop ongoing ingress, but additional remediation (like ventilation or dehumidification) may be needed. An assessment helps determine the right combination of repair and prevention.
What’s the best waterproofing for tiled balconies near the ocean?
Flexible, sheet-based or liquid-applied membranes with UV and salt resistance are ideal. These can handle movement and outdoor exposure without breaking down. Compatibility with tiling systems is also essential to avoid future failure.
