Patching Hole Around Conduit In Concrete Wall

The standard method of prelocating a hole in a poured concrete wall is to position a sleeve where the hole is needed.

Patching hole around conduit in concrete wall.

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. I considered a lot of options.

Use a hammer and chisel to remove loose concrete from the hole. Press hydraulic cement into the hole with a small trowel or putty knife. 4 scoop up about cup of prepared mortar mix. Spray the surface and inside edge of the cinder block hole with enough water to dampen the block but not so much that the water runs down the wall.

Also try to flatten out the bottom of the hole to create a stable level surface for the new patching material. 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. Both procedures follow the local codes for poured concrete walls in my location.
