Water Ingress Detection & Diagnostics

Our water ingress leak detections are designed to diagnose the root cause of water ingress for residential, commercial, and industrial properties and develop practical, cost-effective solutions. We conduct on-site investigations, moisture testing and condition assessments, providing detailed reports that outline defects, risks and repair recommendations. 

Following our inspection, you will receive a comprehensive diagnostic report detailing the location, root cause analysis, and severity of the water ingress. Using with high-resolution photographic and thermal imaging evidence, along with a clear roadmap for remediation, you will have the exact documentation needed to complete the repair process.

Water Damage Assessments

Unresolved water intrusion and hidden moisture compromise more than just the structural integrity of your building; they can significantly impact the quality of the air you breathe. When dampness is left unchecked, mould can develop rapidly, creating an unhealthy environment for occupants and causing long-term damage to your property.

Our comprehensive assessments are designed to bridge the gap between building science and occupant well-being. Rather than simply treating the visible symptoms, we conduct a thorough investigation to identify the hidden mechanisms driving the moisture issue. We provide the clarity and direction needed to properly resolve the problem from the ground up.

This is a vital tool for Strata Managers and Real Estate Agents, providing:

Moisture Mapping & Thermal Imaging Data: Non-destructive testing diagnostics that clearly visualize the hidden path of the water leak.

High-Resolution Photographic Evidence: Clear, labelled photos showing the exact points of failure and affected structural elements.

Root-Cause Analysis: A definitive breakdown of why the membrane failed (e.g., building movement, poor installation, age, or lack of drainage).

Compliant Scope of Works: A detailed rectification plan written in accordance with Australian Standards (AS 3740 for wet areas and AS 4654 for external areas).

Your Questions Answered

Water Ingress Inspection (Finding the Source): This is a forensic, external investigation into how water is breaching your building envelope. We use specialized equipment to track down structural defects like failed balcony waterproofing membranes, roofing leaks, facade cracks, or rising damp.

Water Damage Assessment (Evaluating the Impact): This is an internal investigation into what happened after the water got in. Water quickly migrates behind walls, under floors, and into insulation, creating hidden wet zones and toxic mould. The goal of this assessment is to map out exactly how far the moisture has traveled, test your indoor air quality, and provide a blueprint to dry out the building and safely remove the mould.

Water ingress refers to water entering a building where it shouldn’t—often through failed waterproofing, cracks, construction defects, or poorly sealed junctions. Over time, it can lead to structural damage, mould growth, and internal deterioration.

Yes, we provide both inspections and remedial water ingress repairs. Once the issue is identified, we can carry out targeted rectification works to restore compliance and prevent further water entry.

Yes. Ongoing moisture from leaks or failed waterproofing systems creates ideal conditions for mould growth. This can affect internal air quality, finishes, and overall building health if not addressed properly.

Urgent signs include persistent dampness, salt deposits, peeling paint, and deteriorating plaster. Mould growth and musty odours often accompany rising damp. These symptoms usually worsen over time if untreated. Structural materials may also degrade. Early action prevents further damage and health concerns.

Our initial diagnostics are entirely non-destructive. We use high-resolution thermal imaging to detect the thermal signature of moisture, alongside non-invasive dielectric moisture meters that measure subsurface dampness behind plaster and render without leaving a mark.

We service a wide range of properties, from small residential spaces to large-scale commercial structures. Because building physics, water behavior, and Australian construction standards apply across all built environments, our diagnostic equipment and methodology are highly adaptable. Our core service areas include:

Residential Homes

Strata & Multi-Residential

Commercial & Retail Buildings

Because every property and water issue is unique, our fees are tailored based on the size of the building and the specific services required. For more information, please contact us with your site specific needs and we can provide you with the fee proposal.
