A vibrating screed comprising a screed member, a motor, and an exciter assembly configured to vibrate the screed member in response to receiving torque from the motor via a driveshaft. The exciter assembly includes a first eccentric mass fixed on the driveshaft and a second eccentric mass axially and rotationally moveable along the driveshaft between a first position and a second position in which the second eccentric mass is axially closer to the first eccentric mass than in the first position. The vibrating screed further comprises a mode selection member to switch the exciter assembly between a first, low vibration mode, in which the second eccentric mass is in the first position, and a second, high vibration mode, in which the second eccentric mass is in the second position.

Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

A remote controlled vibration imparting device for a concrete finishing tool uses a housing having a chamber surrounded by an inner surface of the housing. A vibrator with a support, a rotor with a shaft and weighted body, a motor, and a resilient link between the shaft and the motor is positioned within the housing chamber. The vibrator also includes a resilient band to separate the vibrator from the housing inner surface. First and second adaptors are employed for the housing to be placed between the handle and the terminus of a concrete finishing tool.

A decorative concrete product and method of making the same is provided. The concrete surface carries a unique textural and visual decorative pattern that is troweled over the uncured surface. The decorative pattern strategically conceals any imperfections in the concrete surface. A decorative finishing tool is utilized to create a unique and consistent pattern throughout the exposed surface of the concrete. Unique visual patterns may include any aesthetic design including wood grain, or lightly finished honed or cut stone. The decorative finishing tool may be configured so that varying textures and contours may consistently be imprinted throughout the concrete. Advantageously, the cured concrete retains the durability of a concrete surface while carrying a visually and texturally appealing appearance.

The apparatus and method comprise a concrete float with a vibratory additive broadcaster assembly attached therewith. The broadcaster assembly is suspended above the plane of the finishing tool with a vibratory source attached. The broadcaster assembly is filled with an additive and the apparatus is placed on a wet, concrete surface that is to be treated and finished, by a user. Actuation of a power switch by the user activates the vibratory source resulting in the substantial broadcast of additive on to the concrete surface at the desired location(s) on the slab as determined by the user. Vibration damper devices are utilized to minimize the vibrations experienced by the float. The additive is integrated into the concrete or other wet surface by passage of the float over the surface being treated.

A leveling blade mounts onto a support bracket of a vibrating screed, and a vibrating screed includes the same. The leveling blade has a substantially vertical portion for mounting onto the support bracket, as well as a substantially slanted portion and a substantially horizontal portion, which results in the leveling blade having a particular profile. The vibrating screed includes also a vibration-generating assembly, being operatively mounted onto the support bracket of the vibrating screed for imparting vibrations to the leveling blade via the support bracket so as to enable carrying out a surfacing of a substantially malleable material with the vibrating screed by passing the leveling blade provided with vibrations about the substantially malleable material. A kit is also provided for assembling such a vibrating screed.
