Abstract: An edger is provided that includes a cylindrically shaped attachment member that includes at least one tooth for interlocking relationship with another attachment member. The interlocking relationship prevents relative motion between the attached edgers. The edger further comprises a plurality of arcuate members that help support the wall against the restrained pavers and which provide stiffness to the wall.

Abstract: The present invention relates to an apparatus and method for selectively dispensing reinforcement material into a concrete component. The apparatus is capable of providing, positioning and embedding any form of rolled reinforcement materials into both prefabricated concrete components and cast-in-place concrete components which can be operated by a minimal number of personnel in a timely and economical manner, and which can be used to mass produce concrete components.

Abstract: A fabricated concrete foundation wall is provided with a plurality of insulation panels and reinforcing ribs to improve strength and reduce the density of the wall panel. The foundation wall panels are easily placed and interconnected together to quickly provide a foundation adapted to support the main walls of a home, for example. The foundation panels in one embodiment generally include a facewall that may have at least one carbon fiber band positioned horizontally therethrough to provide additional stiffness.

Abstract: A precast concrete storm water vault comprised of modular precast concrete components is provided. More specifically, a vault is provided that consists of a perimeter of footings with integral vertical walls extending therefrom that supports precast concrete roof panels that comprise the top horizontal structural for the placement of pavers, a fill, base, or a driving surface. The storm water vault disclosed may be combined with a filtration system and has easily removable roof panels that facilitates maintenance and cleaning.

Abstract: A subgrade vault with a latching cover. The vault includes a peripheral wall with an open access port at the top. A peripheral ledge surrounds the access port. A cover to close the access port fits inside it, with a latch assembly inside it and a retractable latch pin disposed to fit in an aperture in the peripheral ledge. The latch pin is retractable by the stabbing motion of a tapered tool against a cam surface on the latch pin. The cover is locked in place merely by pressing down on it.

Abstract: The present invention relates to a method and apparatus for fabricating a reinforced concrete cylinder, and more specifically to a method for centering a reinforcing frame within a form used during the placement of a concrete slurry. One embodiment of the present invention includes a plurality of centering arms that are adapted for selective engagement with the reinforcing frame, thus maintaining it in the predetermined radial location during the fabrication process.

Abstract: A reinforced low density material is provided that includes a reinforcing mesh or other geometry. The reinforcing mesh in one embodiment of the present invention is comprised of an arrangement of glass fibers that are coated with a polymer. The insulative material is formed by placing the reinforcing mesh within a mold, wherein the introduction of a heated expanded polystyrene, for example causes the coating on the reinforced mesh 1 to bond with the polystyrene to create a reinforced insulative material after the composite material cools.

Abstract: An insulative, lightweight building panel is provided with a lightweight, insulative foam core and which includes one or more carbon fiber or steel reinforcements and an exterior concrete face which are manufactured in a controlled environment and can be easily transported and erected at a building site.

Abstract: The present invention relates to an apparatus and method for selectively producing a deformation in a reinforcing frame employed in the fabrication of concrete pipes or other similar construction materials. The deformation maintains the frame in the proper predetermined location inside the concrete form during fabrication to thus produce a concrete pipe with optimum structural properties.

Abstract: An insulative, lightweight concrete building panel is provided with one or more fiber or steel reinforcements which are manufactured in a controlled environment and can be easily transported and erected at a building site.

Abstract: An insulative panel with transverse fiber reinforcements is provided and which is adopted for use with a plurality of building materials such as concrete to create a lightweight, high strength building panel having superior insulative properties.

Abstract: The present invention relates to building panels used in the construction industry, and more specifically composite building panels comprised of an insulative core, concrete, and carbon fiber which are preformed, cast and transported to a building site for modular construction.

Abstract: A precast concrete modular device using thin coffered sections reinforced preferably with carbon and/or glass fiber scrim grids, in between steel reinforced ribs is provided. The thin reinforced sections stiffen the steel reinforced precast frame. The thin sections preferably have a thickness less than about two inches, preferably less than about 1½ inch, and more preferably less than about 1 inch. The resultant modules have an areal weight of less than about 40 lbs. per square foot.

Abstract: The present invention discloses a precast railway crossing slab adapted to extend transversely across the surface of conventional railway ties, with slots or gaps dimensioned and disposed to receive a pair of railway rails therethrough. The crossing slab includes a post-tensioning system in which metal cable strands or tendons are sheathed within plastic tubes and are positioned in the slab mold frame prior, to pouring of concrete. Tendon anchors are also disposed in the slab mold frame prior to pouring. After the concrete hardens, a hydraulic jack is used to tension and anchor the tendons in a stressed condition, thus providing reinforcement to the slab. The railway crossing slab of the present invention may be utilized with or without surface or edge metal plating. Flange way fillers which typically comprise rubber strips extending between the sidewalls of the metal rail and the concrete slab may optionally be employed.
