An in-ground concrete swimming pool is a pool that is custom designed, engineered, and built to fit into the earth and surrounding structures. This type of swimming pool is typically built by excavating out the earth in the general shape of the pool design. Forms are then created to guide the steel and concrete to eventually become the pool shell. PVC plumbing is buried underground and run throughout the pool shell prior to the application of the concrete. A pneumatically applied concrete is cast in and around the plumbing and steel framework to create a unique, custom shaped swimming pool shell. Once hardened, a select blend of tiles, stonework, decorative concretes, and other finishes are added to produce a completed look and feel to the pool. Spas can be integrated into the design to allow for a heated hydrotherapy soaking space.
