Patching Hole Around Conduit In Concrete Wall

Knock away the cracked and crumbling concrete around the hole.

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. If necessary fill the gap in layers of cement to build up the area slowly. Press hydraulic cement into the hole with a small trowel or putty knife. 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.

I considered a lot of options. Use a hammer and chisel to remove loose concrete from the hole. 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.

After hearing that i seriously considered just gluing a piece of plywood over it and calling it a day. Both procedures follow the local codes for poured concrete walls in my location. Also try to flatten out the bottom of the hole to create a stable level surface for the new patching material.
