Moisture mapping is foundational to any serious leak investigation. Before deploying expensive thermal imaging or tracer gas, we measure the moisture profile of the affected area, establishing where water is concentrated, in what direction it's spreading, and at what depth. This builds a 3D picture of the damage that informs the rest of the investigation and quantifies the remediation scope.
We use Tramex MEP non-invasive capacitance meters for surface and shallow-substrate readings, and Tramex CMEX2 pin-meters for deeper substrate moisture content. Both are independently calibrated annually and conform to the British Standard Code of Practice for damp investigation (BS 6576). Every survey produces a written report with location-mapped readings acceptable to insurance loss adjusters and conveyancing solicitors.
Where this service applies
- Investigation of suspected leaks before commissioning thermal/acoustic surveys
- Damp diagnosis (rising damp vs penetrating damp vs condensation vs active leak)
- Pre-purchase property surveys for hidden water damage
- Post-flood damage scoping for insurance claims
- Mould investigation, identifying moisture source supporting growth
- Drying-out monitoring after restoration work
- Floor and wall moisture content assessment for conveyancing
- Building Pathology investigations
