When surveillance is properly and strategically combined with inspection effective maintenance is achieved. Defects usually create hazards that lead to serious or sometimes fatal injuries. Most defects can be discovered at their early stages through visible and detectable symptoms. If they are not rectified promptly some minor defects can develop into serious ones causing a sudden collapse that endangers life and becomes more costly to rectify. Some of the major building defects observed are usually due to
Possible causes for these are defective concrete as a result of aging that is commonly found in old buildings. Persistent water leakage might have affected the steel reinforcement. Weak concrete adds to further vulnerability with the use of salty water in a concrete mix.
These defects can be cleared as follows. Damaged or defective concrete is to be hacked off down to sound substrate and patched up with mortars such as cementitious mortars and Resin-based (or epoxy resin mortar) mortars based on the requirement. The rusty reinforcement bars should be properly cleaned, and be primed with suitable cement or epoxy based primer especially manufactured for the purpose needs to be used otherwise the bonding strength between concrete and steel bars will be impeded. If any circumstance arises that the diameters of the reinforcement bars are found substantially less than their original sizes after the “rust shells” have been removed, the addition or replacement of steel bars is to be made. If the defective concrete is extensive and penetrates beyond the steel bars, partial or complete demolition and re-casting of the affected items needs to be done.
The leakage problem of the roof can be cured by replacing aged waterproofing construction. Some of the materials used for reconstruction should be liquid applied and membrane applied which require cement sand screeding. To locate the source of the leakage the pipe should be exposed to visual inspection along with that pressure test should be carried out.
