Patching hole around conduit in concrete wall.

If you can insert a small bottlebrush to get out any dust or silt that s on the concrete this will really help ensure patching success. After hearing that i seriously considered just gluing a piece of plywood over it and calling it a day. Also try to flatten out the bottom of the hole to create a stable level surface for the new patching material. Both procedures follow the local codes for poured concrete walls in my location.

Knock away the cracked and crumbling concrete around the hole. I considered a lot of options. The standard method of prelocating a hole in a poured concrete wall is to position a sleeve where the hole is needed. Press hydraulic cement into the hole with a small trowel or putty knife.

Pack the material in tightly and make sure the cement connects with both the pipe and surrounding wall. The guys at home depot had a lot of fun lamenting the fact that the hole existed to begin with and then suggested that i build a mold on one side of the wall and fill it in with a pour of concrete. You want the concrete surface in each hole to be perfectly.
