Newcastle Waterproofing
Waterproofing is a non-negotiable component of any long-lasting structure, particularly in regions like Newcastle where heavy rainfall, coastal humidity and clay-based soils can accelerate water damage.
When water penetrates a building—whether through a basement wall, bathroom floor or cracked facade—it can cause structural decay, mould growth and interior damage. Effective waterproofing creates a continuous barrier that stops moisture before it enters, ensuring long-term protection for residential and commercial properties alike. Properties often require a combination of above- and below-ground treatments, including membranes, sealants and drainage systems tailored to site conditions. The right approach depends on building age, construction materials and intended use of each area. Legend Waterproofing applies advanced systems that perform in all of these settings with a focus on durability and compliance.

Frequently Asked Questions
What areas of a property typically need waterproofing?
Common areas that require waterproofing include basements, rooftops, bathrooms, balconies and retaining walls. These areas are most prone to water exposure and structural movement. Waterproofing helps prevent leaks, mould, and material degradation over time.
How long does a waterproofing system last?
Most waterproofing systems last between 10 to 20 years, depending on the materials used and the conditions they’re exposed to. UV exposure, foot traffic, and building movement can shorten lifespan. Regular inspections and timely repairs help extend the effectiveness of your system.
Is waterproofing mandatory for all builds?
Yes, waterproofing is a requirement for specific areas under the National Construction Code in Australia. Wet areas such as showers and external balconies must have compliant membranes installed. Non-compliance can lead to failed inspections and costly rectification work.
Can waterproofing help prevent rising damp?
Yes, appropriate waterproofing methods such as damp-proof courses and negative-side treatments can significantly reduce rising damp in older properties. These systems block moisture from seeping through foundation walls and slabs. Additional ventilation and drainage may also be recommended for long-term control
