Maintenance and Diagnostics
It is known that good quality membrane does not require extensive maintenance. However, due to external factors it might have some defects even without reaching its design life. Therefore, regular inspections should be carried out methodically at regular intervals to detect the defects. Some 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 moisture entrapped underneath the membrane.
Diagnostics of Defect
Thermography
Thermography can be used to identify the position of water leakages. 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.
Infra-red (thermographic) inspections
Infra-red thermographic surveys can be undertaken to identify moisture build up within your building’s structures. Moisture within a building’s envelope will have a significant impact on its overall performance and infra-red thermography can be utilised to identify any such performance failures. Thermographic imaging is particularly useful in flat roof assemblies where moisture within the building’s structure can be very readily established.
Exposed waterproofing membranes will deteriorate (unless properly protected), by exposure to ultra violet radiation (UV), causing the membrane to degrade and lose its integrity creating pathways for water to enter into the building concerned.
Leakages can be detected using infra-red thermography the areas of entrapped water within a roof construction allowing targeted and effective repairs. In using such investigative techniques, it can produce a definitive visual image of the water ingress or insight into missing insulation layering can be obtained. Providing you with a complete assessment of your buildings performance combined with the information of how best to resolve the problem area.
