Our transparent, collaborative approach addresses the full spectrum of waterproofing challenges affecting commercial properties in this affluent spa town and its surrounding areas.

Our services encompass professional roof condition surveys, advanced waterproof integrity testing, and systematic building leak investigations, enabling you to engage targeted repairs and protect your investment with complete confidence.

How We Work

  • Planning

    Each investigation begins with a thorough consultation, where we will review your building's construction, waterproofing specifications, and any known concerns. This preparation enables us to select the most appropriate testing methodology and develop an efficient, workable plan that you can feasibly meet within your current operational capacity.

  • Testing

    Our qualified leak detection technicians use industry-leading equipment calibrated for commercial applications. Employing techniques including low voltage testing and pinhole detection for conductive substrates with a membrane system, we methodically survey waterproofed areas to identify defects accurately.

  • Evidence

    Every detected leak or source of water ingress is meticulously documented through precise location mapping, comprehensive photography, and detailed measurements. Our diligence and thoroughness provide contractors with exact target areas, streamlining repair specification and eliminating guesswork.

  • Recommendations

    We provide clear recommendations prioritised by severity and risk. Our guidance addresses immediate remedial needs alongside longer-term building maintenance strategies, helping you allocate resources effectively whilst protecting your property from escalating damage.

Client Testimonials

I’ve worked with Thornton’s team for nigh on 10 years and I’m yet to be disappointed by any aspect of their business or interaction with any of their staff. I feel that the collaborative approach we have when working together not only benefits our site in a speedy response and solution, but it also strengthens our relationship with our onsite client team, building in faith that together we can self-solve most, if not all issues. Working with Wendy and the onsite teams is nothing short of a pleasure. I would highly recommend using Thornton Consulting Group for all investigative services when it comes to finding leak issues.

FAQs

How accurate is electronic leak detection compared to visual inspection?

Electronic leak detection is fundamentally more accurate than visual inspection for identifying membrane breaches because it detects problems that aren’t inherently overt or visible. Visual inspections can only identify obvious surface defects such as splits, blisters, or displaced materials. However, many of the most problematic leaks occur at pinholes, seam failures, or defects at penetrations that show no external signs until significant water damage has already occurred internally. Electronic testing identifies these hidden faults by detecting the electrical conductivity changes when water penetrates through waterproofing membranes, locating breaches to centimetre-level accuracy.

What information do you need from us before starting?

To plan your survey effectively, we find it helpful to have basic information about your building and the issues you’re experiencing. This includes the approximate roof area and type of waterproofing system if known, details of when any leak problems were first noticed and whether they’re constant or intermittent, any available architectural or structural drawings, information about previous repairs or maintenance, and details of your operational schedule so we can minimise disruption. Don’t worry if you don’t have all this information readily available; we can often establish what we need during our initial consultation.

Do you offer ongoing maintenance contracts?

Yes, we provide planned maintenance programmes tailored to your property portfolio’s needs. These typically involve regular scheduled inspections at intervals we recommend based on your roof’s age, type, and condition, combined with electronic integrity testing to identify emerging issues before they cause problems. We’re happy to discuss a maintenance strategy suited to your specific building(s) and budget, whether that’s annual inspections for newer roofs or more frequent monitoring for older or failing roofs.
