This swimming pool consists of a first sheet or layer of concrete (1) forming the foundation, on which general "C" profile prefabricated reinforced concrete parts (2a, 2b, 2c) are laid, which have tongues or clips (25, 26) projecting from the reinforcement, holes (22) to assemble side torque means (3, 31), vertical channels (23) which define a housing containing concrete filler (4) with expansive additives, and vertical bevels (24) to place sealing filler (5) of the joints. It also consists of a...

A rust-proof window well manufactured from a composite material. The window well may have integrally formed steps to assist in egress from inside the well. Walls forming the well typically are 1/4 inch thick, or greater. While generally made with a spray-up process from a glass/epoxy composite, the well may be manufactured from a variety of composite materials with corresponding manufacturing techniques.

Forms for building and assembling water containment holders such as but not limited to inground spas, pools, manmade ponds and fountains. The forms can have an L-shape with downwardly protruding members for allowing the forms to be placed about a base foundation having receiving openings for the protruding members. Lower walls, seats and backrests can be placed about the forms to assemble the water containment holder. All the components including the base, the forms, the seats, lower walls, and ...

An emergency storm shelter providing save haven for occupants during tornados and windstorms. The shelter features an elongated cylinder with sealed ends forming a center cavity for occupants during a storm. Emergency access is provided by at least one access tube formed having an interior passage therethrough communicating with the interior passage of the cylinder. The access tube is of a length to extend above the surface of the ground in which the elongated cylinder is buried, and can also be...

A pressure barrier liner is an assembly of low permeability membranes disposed on above the other. A region is encapsulated between each adjacent pair of membranes. A pressurized fluid such as air or water is introduced into a selected group of the encapsulated regions to pressurize them to a selected pressure or pressures, thereby ensuring that any flow through the membranes or through disruptions in the membranes will be from within the pressurized regions to the regions outside the membranes ...

A bracing system for in-ground steel and vinyl swimming pools that allows the pool to be constructed very quickly and without the use of concrete either on the braces or around the bottom perimeter of the pool is described. The bracing system works by properly using the resistance of undisturbed earth around the perimeter of the pool (after excavating for the pool) and the weight and correct placement of the back-fill material reintroduced around the pool. Each earth brace system is comprised of...

A replacement pool step for installation into the interior corner of a swimming pool is disclosed. The pool step is installed such that the vinyl liner of the pool does not cover the pool step but rather is installed in such a manner that it is sealed to the front of the pool step.

An above ground pool having identical sized panels coupled together to form the perimeter of the pool. Post structures located at the union of adjacent panels include angle members that span the union of adjacent panels and determine the angle at which adjacent panels extend with respect to each other. Different sets of angle members can be utilized to form different angles between adjacent panels to establish different sizes of pools having different numbers of panels.

A method for construction of an in-ground swimming pool includes the steps of excavating a hole with a wall, providing a shelf associated with the wall and installing a footing form structure with a form member in association with the shelf. The footing form member is leveled and a concrete footing is poured in a footing form volume defined by the wall, the shelf and the form member. Wall form panels are placed on the footing and a concrete wall is poured therebetween.

A swimming pool comprising a perimetral structure supporting the water holder being made of plastics material and is characterized in that the perimetral structure is apt to rest on the surface on which the swimming pool is to be installed, the perimetral structure comprising tensioning members being fitted to it and transversally arranged from side to side of the perimeter in an underlying arrangement. The perimetral structure comprises base supports being transversally arranged along the swimm...
