Maintenance and Diagnostics
Regular inspections should be carried out methodically at regular intervals to identify any defects phenomena. Design of parapet wall is crucial to maintain a low concentration of fungi spores and minimise chances of further development of aglae defects. The following are recommended maintenance practices:
- Monthly cleaning to clear up any stains before it become stubborn stains.
- The wall surfaces are scrubbed clean once a year
- For the tiled floor and wall, have to be mopped more often.
- The surface drains have to be flushed to clear silt and dirt twice a year to prevent blockages.
- Engineer will held regular inspection to check the performance of the pump that pumps out surface water.
- Carry out daily inspection to check defects and problems so to ensure rectification is done as soon as possible.
A checklist is useful to ensure thorough inspection.
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.
