A pool, preferably a plunge pool, that can be prefabricated and on site installed in a short space of time is provided. The pool is integrally formed, resulting in a unitary pool shell having a floor, one or more sidewalls connected to the floor, a surface, such as a step or bench, extending from at least one of the sidewalls; and a peripheral wall extending from the surface to the floor.

Below grade fluid containment structures, which may include a foam floor and a foam wall extending upward from the floor, the foam wall being formed from foam panels. A granular material is provided for reducing hydraulic soil pressure against an exterior face of the foam wall that would otherwise be exerted by the soil, if the soil were allowed to be positioned up against the foam, particularly the foam wall. The well-draining granular material may be gravel, crushed stone, or the like, which provides better drainage as compared to the surrounding soil material. The interior face of the foam is coated with an elastomeric abrasion resistant impact resistant polymeric coating that seals the below grade interior space defined between the floor and the wall in a seamless water-tight configuration.

The present invention relates to a new construction method to build water basin bodies of water that can be used for recreational activities such as surfing, wake boarding, body boarding, water skiing, kayaking, canoeing, river surfing, lazy rivers, tubing rivers, swimming, scuba and other recreational water activities. The present invention construction method can be used in water basins, pools, lagoons, ponds, lakes, surf lakes, surf pools, reservoirs, bodies of water and rivers.

A single unit precast concrete tub (1) formed out of concrete wherein a plumbing system (10) and electrical system (11) are encased within preformed concrete walls. The fully encased plumbing system protects the pipes against damage and frost. Support brackets (15) are formed on an exterior surface (4) of the side wall (2) to provide attachment points for hoisting the precast tub for transportation and installation. The support brackets also provide attachment points for building auxiliary structures, such as decks, around the precast tub.

A building system comprising a combination of precast or prefabricated structural elements to serve as skate parks, swimming pools, or community gathering places; and to provide refuge such as tornado shelters. Precast or pre-manufactured modular cells have an open bottom, a first and second side wall, a rear wall, and a functional top surface. The functional top surfaces of the modules include an inclined or curved surface. When combined, the top surfaces form useful areas such as a skate park, swimming pool, or amphitheater seating. Sleeves, keys, and other features facilitate the assembly of the modules. A cast slab may be poured after assembly; or the modules may be secured to a slab. Example modules include a Flat Ramp Block, a Circular Ramp Block, and a Circular Bowl Block, a stair block, and a ledge block.
