Diagnostic Methods

Thermal Imaging Leak Detection

Infrared (IR) thermography is a non-destructive diagnostic method that uses a high-resolution thermal camera to visualize surface temperature differentials across a building envelope, roof, slab, or wall. Because water has a much higher thermal mass than the surrounding dry substrate, areas saturated by leaks or trapped moisture cool down and warm up at a different rate to their surroundings — appearing as distinct thermal anomalies on a thermogram. TEXSA uses calibrated FLIR cameras and supporting moisture instrumentation to pinpoint hidden roof leaks, wet insulation in built-up and PU-foam roofing, concealed plumbing leaks behind walls and slabs, façade water ingress, and thermal-insulation discontinuities — all without destructive opening of finishes. The method is most powerful when combined with a follow-up moisture meter sweep, an as-built drawing review, and (where required) a small confirmatory core to validate the IR findings before remedial scope is locked in.
