Water ingress is the leading cause of defects in Sydney apartment buildings. In a Class 2 environment, a leak in one unit is rarely an isolated incident—it often indicates a systemic failure of the membrane system affecting multiple floors and common property. Quick patch-ups by a handyman often mask the problem while structural damage worsens.
We provide comprehensive remedial waterproofing services designed for longevity. From rooftop membranes and balcony re-sealing to basement tanking, we strip back defective areas to diagnose the root cause. Our team installs certified waterproofing systems that comply with current Australian Standards, providing the Body Corporate with warranties and peace of mind. If your building has a history of leaks, it is time to invest in a professional, building-wide solution.
