Methods and devices for repairing concrete surfaces

Abstract

Methods for repairing holes in a surface, for example, in a concrete surface, cement slurry hoppers, cement slurry funnels, and cement slurry hopper assemblies are disclosed. The methods include positioning a barrier, such as, a board, over a hole in a surface wherein a portion of the hole is not covered by the barrier and a cavity is formed behind the barrier; mounting a hopper over the portion of the hole not covered by the barrier; pouring a cement slurry into the open top of the hopper to substantially completely fill the cavity with cement slurry; allowing the cement slurry to harden; and then removing the hopper and barrier from the surface to reveal a repaired hole in the surface. A cement slurry funnel may be used to fill the hopper. The cement slurry hopper and the cement slurry hopper assembly having an isolation plate are also provided.

Dependencies are inferred from the claim text.
