We have been contracted by a number of pool installers this year to assist them in installing pools using “geofoam” as part of the design. There are some very good reasons why you would want to use this foam material in pool construction, as well as in other construction applications. With regard to pool construction, Geofoam is a great choice because it simplifies the construction process itself. It provides a medium onto which the concrete can be directly formed, rather than going through a more expensive process of forming and filling structures entirely of concrete.
