Common Waterproofing Issues in Box Hill, NSW

With a mix of modern and heritage buildings, a sloped landscape, and seasonal downpours, Box Hill frequently encounters waterproofing difficulties. Below are the most typical challenges:

Balcony & Terrace Leaks

Many Hills District homes feature spacious balconies and terraces, but improper waterproofing or failing membranes lead to water ingress, tile damage, and structural deterioration.

Roof Waterproofing Failures

Extreme weather changes lead to cracks in sealants, flashing deterioration, and water accumulation, particularly on tiled, metal, and flat roofs. This can cause roof leaks and expensive repair work.

Bathroom & Shower Waterproofing Issues

Improper membrane application is a common issue in older buildings and even some newer constructions, leading to leaks in showers, mould accumulation, and weakened flooring structures.

Basement & Retaining Wall Dampness

When homes are built on sloping blocks, they frequently encounter hydrostatic pressure that causes rising damp, basement water penetration, and structural degradation over time.
