There are two primary ways to apply concrete for an inground pool. One method is called 'gunite' and it is dry-mix high velocity concrete application process. One of the benefits of applying a dry-mix includes not having to keep a mixture of wet concrete moving before application because the base materials are instead mixed on site using mixer trucks, an air compressor and a gunite 'gun'. It also reduces the likelihood of air pockets or 'voids' forming in the shell as the high-velocity application does not allow enough time for air to become trapped.
The other application, that is sometimes implemented by CPC, is called shotcrete. It is a wet-mix medium velocity application whose strength primarily comes from the quality of the mix being applied. The mixture is deposited through a hose and is then meticulously troweled by our tradesmen to prevent any voids from forming. CPC will always use industry-leading materials in all pool shell shotcrete applications.
There is no discernable difference in the end result between the two applications and we reserve the right as the builder to choose which application would work best for a specfic build. There is no difference in price.
