A method for repairing a multi-sided structure protruding from a first surface. The method comprises mounting a retainer to the first surface, coupling a first brace connector component of a first brace to a first panel, coupling the first panel to a primary retainer connector component of the retainer, coupling a second brace connector component of the first brace to a secondary retainer connector component of the retainer, and introducing a curable material into the space between the first panel and the multi-sided structure, the first panel acting as at least a portion of a framework for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the first panel.

A stay-in-place concrete formwork system allows stucco to be applied directly to the formwork, avoiding the need to provide a further surface treatment of the wall prior to applying stucco. Apertures are provided on an exterior facing wall of the formwork panel to receive and embed stucco therein. The panel may also be formed with outward stucco-engaging projections. Other features include using rigid insulation to brace the stucco and keep concrete from the apertures, a sealing joint element, extendible panels for use in curved formwork, rainscreen features and an alligator connector panel for adjustable lengths of formwork faces.

A formwork stud system includes a plurality of studs, a top channel, a bottom channel and a plurality of horizontal and vertical rebars. At least one of the plurality of studs is a formwork stud. The formwork stud includes a web and a pair of flanges. The web has opposed side portions extending from the top of the formwork stud to the bottom of the formwork stud and a plurality of lateral spaced apart connectors extending between the opposed side portions. The opposed side portions and the lateral spaced apart connectors define a plurality of spaced apart holes. The holes are configured to allow concrete to flow therethrough. The pair of flanges extend generally orthogonally from the opposed side portions of the web.

A stay-in-place lining is provided for lining a structure fabricated from concrete. The lining comprises a plurality of panels connectable via complementary connector components on their longitudinal edges. Each panel comprises a first connector component on a first longitudinal edge thereof and a second (complementary) connector component on a second longitudinal edge thereof. The lining comprises at least one edge-to-edge connection between the first connector component of a first panel and the second connector component of a second panel, the edge-to-edge connection comprising a protrusion of the first panel extended into a receptacle of the second panel through a receptacle opening. The receptacle is shaped to prevent removal of the protrusion from the receptacle and the receptacle is resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the edge-to-edge connection.

Concrete form assemblies having insulating foam panels are created using locking members embedded within the insulating foam panels and ties each having a pair of side rails for coupling two insulating foam panels together at a predetermined distance apart, the locking members and side rails being adapted so that either side rail can be coupled to either locking member and either of the ends of the rails and locking members can be toward the top or bottom of the assembly when the rails are coupled to the locking members.

A composite wall panel having a front surface, a rear surface, and side surfaces extending therebetween is provided. The panel includes a cured composition of pieces of cellulose and/or chaff and at least one binder. A wall assembly is also provided. The assembly includes: a frame including a plurality of linearly arranged elongated studs having a top end, a bottom end, and a first longitudinal side and a second longitudinal side extending between the respective ends; a plurality of interconnected wall panels mounted to the first side of the elongated studs of the frame to form a first wall portion; a plurality of interconnected panels mounted to the second side of the elongated studs to form a second wall portion; and an insulating layer inserted within a cavity between the first wall portion and the second wall portion.

A method for manufacture of a fire-proof and insulating prefabricated building wall comprising a wall core of an expanded, foamed plastic material, such as EPS (expanded polystyrene), with an integrated reinforcement structure and a coating of a cementitious material.

The invention is the interior face attaching mechanisms of a plastic injection molded flow-through grid forming grid panel that is used as a form for concrete/cementitious material. A “T” or nub catch is formed by the plastic injection mold halve sections at the outer ends of interior face extended vertical grids such that during a concrete/cementitious pour the “T” or nub catch, and attached forming panel connecter tie or webs, does not unduly block the flow of the concrete/cementitious material from flowing through the grid openings. The “T” or nub catch enables forming panel tie or web connecters to slide down vertically along the interior face of the concrete/cementitious material flow-through grid forming panel and downward attach to the “T” or nub catch.

The insulating concrete form system includes longitudinal and corner block assemblies each having a pair of side panels configured with tie receivers interacting with panel spacing ties to hold the side panels in an opposing manner and leading edges with an alternating arrangement of projections and recesses for interlocking with neighboring block assemblies. Each panel spacing tie includes a mid-support section interposing in between and connecting to a pair of end sections by a living hinge with each end section being configured with a flange member for placement within an opposing spatial wedge of the tie receiver, whereby the living hinge possesses the capability of allowing the side panels to move inwardly toward one another in a racked position to yield compactness of the longitudinal block assembly for economical transport. The corner block assembly also includes corner panel spacing ties to supplementally reinforce its structure to withstand hydrostatic blowout caused by poured concrete.
