Methods and apparatus are provided for finishing a composite floor. The apparatus includes a grouting pan configured to be affixed to the rotating head of a finishing machine. The grouting pan has a planar bottom surface and a curved sidewall. Grouting pans are rotated over a prepped surface such that the curved sidewalls trowel the mortar onto the rough composite surface and the bottom surface which is in contact with the prepped floor forces the mortar into the surface voids such that a grouted surface.

Systems and methods for treating concrete, which include wetting a surface of concrete with a colloidal silica and, with silica on the surface, finishing the surface. The surface may be finished with a power trowel.

Embodiments relate to a flex hub mount for a circular brush assembly. The flex hub mount includes a disc having a disc upper surface and a disc lower surface, a disc aperture, and a disc rib extending from the disc upper surface. The flex hub mount includes a flex pad having a flex pad aperture. The flex pad is dimensioned to rest on a portion of the disc upper surface between the disc aperture and the disc rib. The flex pad aperture and the disc aperture are in vertical registry. The flex hub mount includes a plug disposed within the disc aperture. The plug is configured to connect or be held adjacent to the flex pad. The plug and the flex pad are configured to close the disc aperture such that the disc aperture is sealed.

A trowel system for finishing a concrete floor is disclosed. The system may include a first rotor and a second rotor configured to axially rotate at a same speed in opposite directions. The system may further include a sensor unit configured to detect a concrete floor boundary or a presence of an obstacle on the floor when the system moves on the floor. The system may further include a processor configured to activate a first rotor rotation and a second rotor rotation, and obtain inputs from the sensor unit responsive to activating the first rotor rotation and the second rotor rotation. The processor may further generate a concrete floor two-dimensional (2D) map based on the inputs obtained from the sensor unit, and control a first rotor operation and a second rotor operation to cause a system movement on the floor based on the concrete floor 2D map.

A concrete surface processing machine (100) for processing a concrete surface, wherein the concrete surface processing machine is arranged to be supported on the concrete surface by one or more support elements (150) extending in a base plane (101) of the machine parallel to the concrete surface, wherein the concrete surface processing machine is arranged to rotate (R) about an axis (C) normal to the base plane (101) by the one or more support elements (150), wherein the concrete surface processing machine comprises control unit (110) connected to at least one laser range finder (120) arranged pointing in a fixed direction from the concrete surface processing machine, and wherein the control unit (110) is arranged to determine a boundary geometry of the concrete surface based on a sequence of ranges obtained by the laser range finder (120).

One method for finishing a surface includes utilizing a hovering surface finisher with a plurality of attachments and finishers coupled thereto. The surface finisher images a grid on an unfinished surface via a camera and a GPS tracks the location of the surface relative to the surface finisher. A user may program specified parameters, including height and angle above the surface, and speed and time at which the surface finisher flies across the grid to finish the surface. The system operating this process may include a connector that attaches the finisher to the surface finisher and sensors for determining the locational parameters. Utilizing the precise locational information from the sensors, the surface finisher may create various textures on the surface that increase the surface's longevity and safety by reducing slip and fall injuries.
