A method of installing mastic joints on a paved surface is described. The method of installing mastic joints may be used as a repair (i.e. erosion of the paved surface at the joint) or in connection with a new installation of the paved surface. The method of installing mastic joints made include installation with joints that have a structure at the joint terminus. The method produces a joint that is resistant to infiltration of water, fuel, and salt, including mixtures thereof. The method further produces a mastic joint that is thermally resistant and produces longevity of use.

An array of anode assemblies for insertion at a plurality of locations in a gap between a section of a reinforced concrete structure and another solid structure is provided. Each anode assembly comprises an expandable member, an anode attached to the expandable member for protecting a steel reinforcement in the reinforced concrete structure, and an anode connector for interconnecting the array of anode assemblies. During use, each anode assembly of the array of anode assemblies is inserted into the gap, between the section of the reinforced concrete structure and the solid structure, at the plurality of locations. The expandable member of each anode assembly is configured to expand so as to press the anode into contact with a surface of the reinforced concrete structure.

A concrete slab joint forming system and method for forming a joint between adjacent concrete slabs. In various embodiments, the concrete slab joint forming system includes a concrete slab joint former, an extension connector, a cross intersection connector, a tee intersection connector, an end connector, a field cut connector, and/or any combination of any quantity of these components.

An illustrative example embodiment of an assembly for making a concrete expansion joint insert includes an extruder a device that receives material from the extruder. The device includes a flow path through the device and at least one internal feature that directs the material away from a middle of the flow path and toward outside edges of the flow path to establish an approximately equal flow rate of the material through the middle and outside edges of the flow path.

A building deformation joint waterproofing system with a bonding-type built-in water stop structure and a method based thereon are provided, which relate to the technical field of building waterproof structures. The system includes: a concrete structure, on which a building deformation joint is disposed; a water stop structure, which is elastic or stretchable, and disposed in the building deformation joint; and a first bonding layer, disposed between the water stop structure and an inner wall of the building deformation joint. The waterproofing system using the foregoing technical solution bonds the water stop structure to the building deformation joint with an adhesive to form a seamless waterproof construction, thus greatly improving the waterproof ability of the building deformation joint.

An edge protection system for use with concrete flooring, including an initial edge unit having a first part and a second part, the first part for coupling to an edge portion of a first concrete flooring panel and the second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, the system also including an angled edge unit having a first part and a second part, the first part for coupling to another edge portion of the second concrete flooring panel and the second part for coupling to an opposed edge portion of a third, neighbouring, concrete flooring panel, and a modular intersection part at an intersection of the first to third panels, wherein the modular intersection part is adapted to be coupled to the initial edge unit with the initial edge unit extending radially from the modular intersection part in a first direction, and wherein the modular intersection part is adapted to be coupled to the angled edge unit with the angled edge unit extending radially from the modular intersection part in a second direction at an angle to the first direction.

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 protection system is provided in modular lengths, and wherein adjacent modular lengths are coupled by one or more bridging pins.

Thermoplastic compositions useful for sealing longitudinal joints of substrates, for example, roadways and pavement, are provided herein. Formulations including the composition and methods of using the thermoplastic composition to seal longitudinal joints are also disclosed.

A sealing element (100) for sealing a gap (205) between concrete pavements (S1, S2) is disclosed. The sealing element (100) comprises a housing (105) provided in a solid structure. The sealing element (100) comprises a plurality of fins (110) coupled to the housing (105) at outer surface. The housing (105) is compressed and placed between concrete pavements (S1, S2) having a gap (205) may be in between a range of 1 mm to 5 mm. The housing (105) expands outward and the housing (105) is held against walls (202, 204) of the concrete pavements (S1, S2). The plurality of fins grips are held against walls (202, 204) of the concrete pavements (S1, S2).
