Specialist Testing


Based on the principles of inductive electromagnetics, and with no requirement for soil-to-instrument contact, EM surveys offer a rapid survey technique. The instruments have a response that is comparable to that of resistance meters (conductivity is the inverse of resistance) however, unlike resistance meters, EM meters respond strongly to metal.


Instrumentation of structures or mechanical components allows physical changes to be identified, measured and recorded with time enabling informed decisions, or design developments, to be based on actual performance data.


Floor and paving materials must satisfy a variety of both physical and aesthetic requirements. Slip resistance under both dry and wet conditions is a crucial performance quality essential to the safety of pedestrians and vehicular traffic. For vehicular traffic the term skid resistance is used.


Very small differences in the surface temperature can reveal many remarkable qualities about concealed materials. Thermography can be used for the assessment of leakage in flat roofs, location of wall ties, assessment of brick pointing, locating concealed flues, identification of delaminations...
