Basement Leak Detection
Basement water ingress can cause significant damage to your property, from structural deterioration to mould growth and ruined furnishings. At Trace Surveys, we specialise in forensic basement leak detection using scientific methods and cutting-edge diagnostic equipment to identify the source of water infiltration accurately and efficiently.

Our Comprehensive Approach
Unlike traditional methods that rely on guesswork, our methodical investigation process combines multiple advanced techniques to pinpoint leak sources with precision:
- Thermal Imaging – Reveals temperature differentials indicating moisture pathways
- Trace Gas Detection – Tracks water routes through structural elements
- Moisture Mapping – Creates detailed documentation of affected areas
- Endoscopic Surveys – Provides visual confirmation without destructive investigation
- Pressure Testing – Identifies failures in waterproofing systems
Why Basements Leak
Our extensive knowledge of building construction helps us identify common failure points:
- Failed tanking membranes
