Abstract: An improved surface seeded exposed particulate concrete and method of making the improved surface seeded exposed particulate concrete is disclosed. Small particulate is sprayed over the upper surface of the concrete. The particulate may be sprayed using a material sprayer. The particulate may be uniformly sprayed to distances exceeding twenty feet. The particulate is mixed into a cement paste derived from the concrete mixture using floats. A surface retarder is then applied to cover the concrete surface. Subsequently, any surface film is washed from the surface of the concrete and the concrete is cured. The result is a surface seeded particulate with an exposed surface that is flat and is suitable for high traffic areas. The resultant surface may resemble stone, granite or marble.

Abstract: A method of manufacturing a low-moisture penetrating decorative floor surface. The completed floor surface has an appearance of a solid granite slab floor with greater durability. The floor surface has a smooth, flat appearance and can be manufactured in different shapes. The floor surface may be formed over a wood or concrete sub-floor and includes a self-leveling, cementous, low moisture penetrating material to which suitable colorants may be added. The cementous material comprises a topping and silicate-based sealant mixture that is mixed together and poured and leveled over the sub-floor to a desired height. Flakes of contrasting material is then sprinkled over the top surface of the mixture to create a decorative appearance. After drying, the surface is finely ground to a smooth finish. A coat of silicate-based sealant is then applied to the surface that penetrates the porous surface to create a low moisture emitting surface The surface is then ground to a fine surface and rinsed.

Abstract: An apparatus and method for making a sloped floor includes a plurality of elongate arms disposed in radial array relative to a drain. Each arm has a common height along its extent. The radially innermost end of each arm is positioned near or connected to the drain. In a first embodiment, the radially innermost end of each arm is pivotally connected to an adapter that is connected to a center ring that circumscribes the drain. In a second embodiment, each arm is positioned at an incline by an adapter that rigidly joins the arm to the center ring. In a third embodiment, the arms are of shallow construction and are removed after the concrete has been poured. A mounting strip secured to the shower wall may support the radially outermost end of each arm.

Abstract: A support for holding a fluid-impervious barrier and/or keyway form in position during the pouring of concrete is provided. The support carries the barrier and a pair of spaced legs for attachment to a corresponding pair of stable mounting points, such as reinforcement members, bars or the like. The support is positioned such that the barrier is at least partially covered by concrete during the pouring of a first member, such as a slab or footing, and then the remainder is covered when a second concrete member, such as a wall, is poured atop the first member. By placing a plurality of spaced supports at selected intervals, an elongated barrier may be reliably held in place during pouring. One or more forms may also be carried by the support during the pouring of the first concrete member for defining a keyway, either alone or in conjunction with the fluid-impervious barrier. Most preferably, each keyway form is held in place by a separate wing carried on each support.

Abstract: An injection packer, injection packer installation/removal tool, and method of use thereof are especially suited for use in the repair of concrete structures and the like. The injection packer includes a body that is removable from a nonmetallic expansion member that may remain within a repair bore after the injection material is injected into the repair bore. The packer body includes a shank, nozzle, and keyed head with an injection bore therethrough. The nozzle is threaded to engage a nonmetallic nut attached to the expansion member. In use, as the packer body is rotated in a first direction the expansion member is compressed between the nut and the packer body shank, thereby radially bulging the expansion member. At this point fluid may be injected through the injection packer and into the bore and crack(s). As the packer body is rotated in a second direction the expansion member is uncompressed. The packer body is easily detachable from the expansion member.
