The biggest problem that seems to occur with concrete swimming pools is the de-bonding of the plaster lining from the pool shell.
The reason for this defect is usually due to defective construction, including inadequate application of the pool lining.
The Australian Standard governing concrete swimming pools is AS 2783-1992: Use of reinforced concrete for small swimming pools. It sets out the basic requirements for the design and construction of a pool, and is worth a read if you’re in the construction business.
Waterproofing is one of the most common building defects reported by property owners.
Defective water proofing can cause a great deal of damage to property, and is often caused by poor installation practices.
In Queensland, if the value of the waterproofing work is over $3,300, it must be undertaken by a licensed individual. This work requires proper training and knowledge of how to apply waterproofing according to the Australian Standard.
