Maintenance and Diagnostics
Regular inspections should be carried out methodically at regular intervals to detect for any defects. The instruments can be used extensively to diagnose of the defects and to take the action to keep the structure in good condition. The following high-tech instruments and techniques can be used to diagnose leakages on roof.
Diagnostics of Defect
Thermography
Thermography can be used to identify the position of water leakages on roof. The method is based on the characteristics of heat flow phenomenon, in a conductive medium of specific geometry, which is intended to model predetermined boundary conditions. Thermo tracer is a advanced equipment used in thermography technology.
Moisture meter
Detects moisture beneath the surface being tested by measuring the resistance between two low frequency signals transmitted from conductive pads on the base of the instrument. The moisture meter is also used to define the levels of moisture concentration on the roofs. From the readings, the user can quantify the moisture as damp, wet or saturated.
