Over the years we’ve helped answer millions of questions from potential pool buyers and found that when people understand the basic construction process, it empowers them to make a more confident decision regarding which type of inground pool is right for them.
In this article we provide an overview of the basic construction phases of concrete, fiberglass, and vinyl liner pools.
For a more in-depth look comparison of these pool types, be sure to check out our free eBook “Comparing Fiberglass, Concrete, and Vinyl Liner Pools in the Modern Age”.
Concrete Pool Construction
Phase 1: Concrete Pool Excavation
This phase is similar for all three types of inground pools. Earth is excavated and either hauled off-site or used on the property. This is not a decision to make the day excavation begins. Even if your builder does not address dirt removal, be sure to bring it up in advance as it often requires time to find a dump location plus there can be associated costs.
Duration: Several hours to two days depending onthe pool size, equipment used, soil type, and the means of dirt removal.
Project Time Frame: Day 1
Phase 2: Steel Placement
Concrete has a very high compressive strength, meaning it is resistant to crushing forces. However, it has a relatively low tensile strength, meaning it doesn’t naturally flex or bend very well. Adding steel to concrete structures, such as swimming pools, increases the structure's ability to flex and move with it’s environment. A cage of steel bars, also called rebar, is tied together and eventually encased in the concrete shell creating a web of strength and help prevent structural failure.
