More Info

A wide range of test methods.

Electronic Testing

Thornton Consulting was the first UK consultancy to offer this service, starting in early 1987. The process was also adopted early on as a method for confirming the waterproofing integrity of membranes.

Buildings Leaks Investigation

At Thornton Consulting, we have developed an extensive range of procedures incorporating a number of test methods to accurately establish the source of leaks in different aspects of the building envelope and beyond

Roof Condition Surveys

A roof condition survey of an aged flat roof is an invaluable tool for assessing its current performance and condition and can then provide pointers as to the remaining projected lifespan.

Infra Red Thermography

This is a very useful diagnostic method of establishing breaks in the insulation in buildings, as it detects temperature loss through wet or damaged insulation. Where leaks occur, therefore, it can have a beneficial effect in tracing them.
