Patching Hole Around Conduit In Concrete Wall

4 scoop up about cup of prepared mortar mix.

Patching hole around conduit in concrete wall.

You want the concrete surface in each hole to be perfectly. 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. 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. Press hydraulic cement into the hole with a small trowel or putty knife.

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

Knock away the cracked and crumbling concrete around the hole. If necessary fill the gap in layers of cement to build up the area slowly. Pack the material in tightly and make sure the cement connects with both the pipe and surrounding wall.
