A system for automatically and periodically applying moisture to curing concrete that can be transported from one location to another is provided. A portable concrete curing unit receives water from a water source and distributes such water to a moisture applicator that is situated near a curing concrete object. The moisture applicator applies moisture to the curing concrete so as to maintain the concrete object at a desired moisture level during the curing process. The concrete curing unit may contain a power source, a pump, and a controller. The controller is connected to the pump such that the pump will distribute water to the moisture applicator during an activation period. This timing function of the controller allows for a system and method of automatically and periodically curing concrete that can be controlled by the user without extensive need for manual labor during the concrete curing process.

The apparatus of claim 13, further comprising a water level sensor that monitors the water level in the water tank and notifies the user when the water in the water tank falls below a certain threshold level. 15. The apparatus of claim 13, wherein the water tank is mounted on the movable chassis. 16. The apparatus of claim 1, wherein the movable chassis is a trailer that can be towed from one location to another location. 17. The apparatus of claim 1, further comprising a second power source, pump, and controller. 18. The apparatus of claim 1, wherein the water source has a capacity of at least 750 gallons. 19. The apparatus of claim 1, wherein the concrete object comprises at least one of: a wall, a column, and flat concrete. 20. The apparatus of claim 1, wherein the pump is an electric pump. 21. A system for automatically wetting a concrete structure being built remote in the field, the system comprising: a chassis that is portable via an automotive vehicle; a water pump that is positioned within the chassis; a water reservoir that can be coupled to the water pump positioned within the chassis so that the water pump can pump water from the water reservoir; an applicator that can be positioned adjacent the concrete object and is coupled to the water pump so as to apply water to the concrete object during a cure period so as to maintain a desired degree of moisture on the concrete object during the cure period; and a controller that is positioned within the chassis wherein the controller controls the operation of the pump such that the controller can be used to periodically induce the pump to pump the water to the applicator so as to maintain a desired degree of moisture on the concrete object wherein the controller is programmable so that the controller can be programmed to operate without human intervention during the cure period. 22. The system of claim 21, wherein the chassis includes a plurality of wheels permitting the chassis to be rolled over the ground to the location of the concrete object. 23. The system of claim 22, wherein the water reservoir is mounted to the chassis. 24. The system of claim 23, wherein the water reservoir holds at least 750 gallons of water. 25. The system of claim 21, wherein the applicator comprises a planar flexible applicator that can be positioned over the concrete object. 26. The system of claim 25, wherein the applicator comprises a blanket that is soaked with water when coupled to the water pump so as to diffuse water over the concrete object. 27.
