An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, wherein the system includes a retaining clip for retaining the second part to the first part, and the first part is slideable relative to the second part to engage the retaining clip against removal from the first and second parts.

Method of forming a concrete slab to reduce or eliminate control joints includes preparing a substantially flat base, overlaying one or more barriers on top of the base, placing a concrete mixture on top of the barrier(s) and base to form a concrete slab, and allowing the concrete to cure without forming control joints. The base is prepared with a flatness of about inch over 10 feet. A side edge is prepared along a periphery of the concrete slab by extending a vapor barrier from a bottom surface of the slab up the side edge toward a top surface of the slab and covering the side edge. A plurality of post-tensioning cables are positioned to extend through the slab and configured to compress and assist in controlling accelerated displacement of the concrete slab during curing and shrinkage. The concrete slab is formed of an evenly gradated and low slump concrete having high fiber content, minimized cement content, and maximized size of large aggregate.

A vertical exterior wall system has an exterior substrate and a control joint disposed on the substrate. A building material such as stucco covers a base plate of the control joint. An A-shaped ridge extends from the based plate of the control joint and is disposed between a first area of the building material and a second area of the building material, defining a gap. A sealant may be disposed in the gap and may cover the A-shaped ridge, adhering to building materials of the first area and the second area.

A cast-in-place gasket construction for concrete structures such as tunnel segments includes a gasket body having a bottom face configured to be positioned against a surface of an associated tunnel segment. First and second gasket portions of the construction extend in different directions and are connected to each other at a first joint. The gasket portions are made of an elastomeric material having a first durometer on the Shore A hardness scale. The joint comprises an elastomeric material having a second and lesser durometer on the Shore A hardness scale. A method for replacing a damaged frame-like gasket construction is also disclosed.

The present disclosure relates generally to systems for providing a durable water-resistant and fire-resistant foam-based seal in the joint between adjacent panels. A fire-resistant and water-resistant expansion joint seal is provided which includes one more foam members and a plurality of intumescent members interspersed within the foam member or members to provide a spring recovery force and fire resistance.

A building module for use in construction of a building comprising a deck oriented in a horizontal plane and a plurality of hollow structural members extending downwardly from around a periphery of the deck. A method of constructing a building comprising placing a plurality of prefabricated modules according to a floor plan to form a story of the building, pouring concrete into the hollow structural members of the plurality of modules to form structural columns, pouring concrete onto the decks of the plurality of prefabricated modules for form structural slabs, and allowing the structural columns and structural slabs to set to complete the story of the building. Embodiments include a plurality of techniques for sealing adjacent prefabricated modules and for installing a balcony on the prefabricated modules.
