Remedial Waterproofing Services Provided Across Sydney
Our remedial waterproofing Sydney services cover every stage of the process — from investigation to reinstatement. We address the system, the detailing, and the verification that ensures results last. Whether you manage a strata complex or a commercial site, our work is built to perform and comply with Australian Standards.
Inspections & Diagnostics
Each waterproofing inspection is carried out by experienced remedial builders who work closely with engineers and consultants. We provide comprehensive reports with photographs, moisture readings, and recommendations so strata managers and owners know exactly what’s required before works begin.
Negative-Side Solutions
We apply specialised coatings and injection systems that resist water pressure and protect structural concrete from further deterioration. Our negative-side systems are compatible with existing substrates and are installed in accordance with manufacturer specifications for proven performance.
Planter Boxes and Podiums
Planter boxes and podiums are frequent sources of leaks in multi-storey buildings. Over time, blocked drains, root intrusion, and failed membranes allow moisture to penetrate the slab. Our planter box waterproofing Sydney service restores these areas with new drainage layers, root barriers, and flexible membranes designed for landscaped structures.
Reporting for Strata
Transparent reporting is essential for strata and building management. Every remedial waterproofing in Sydney includes photographic documentation, condition summaries, and a record of materials used.

Common Questions About Remedial Waterproofing
Waterproofing problems can develop gradually but worsen quickly once leaks begin. Understanding the causes and solutions helps prevent further damage and unnecessary costs. Below, we’ve answered common questions about remedial waterproofing Sydney to help strata managers, property owners, and builders make informed decisions about maintenance, compliance, and long-term protection.
How Is Remedial Waterproofing Different from New Waterproofing?
New waterproofing is installed during construction, while remedial waterproofing deals with existing structures. It requires investigation, design, and staged works to minimise disruption to occupants. Our remedial approach focuses on diagnosis, compatibility, and compliance — ensuring that new systems integrate effectively with existing building elements.
Do You Service Strata and Commercial Buildings?
Yes. We specialise in both strata and commercial remedial waterproofing Sydney projects. Our team is experienced in managing access, communication, and safety requirements for occupied buildings. We provide reports and updates throughout the project, ensuring strata committees and commercial owners are always informed.
Where Do You Provide Remedial Waterproofing Services?
We provide remedial waterproofing services across the metropolitan area, with a strong focus on the Eastern Suburbs. Our coverage includes the CBD, Inner West, Lower North Shore, Northern Beaches, St George, and Sutherland Shire. If your building is outside these regions, we’re happy to discuss travel for suitable projects. Our remedial waterproofing eastern suburbs team can attend inspections promptly and provide detailed quotes.
How Long Does Remedial Waterproofing Take?
Timeframes depend on the size and scope of works. Small balcony or planter box repairs can take a few days, while full podium or basement projects may require several weeks. We provide a clear schedule before starting any work.
Do You Work Alongside Engineers or Consultants?
Yes. We regularly collaborate with engineers, building consultants, and strata committees. Our reports, test results, and photographs ensure all remedial waterproofing works align with their specifications and project documentation.
What’s Involved in a Waterproofing Inspection?
We perform moisture testing, visual assessments, and targeted openings to locate issues. Reports include findings, photographs, and recommendations for repair or replacement.
