Patching hole around conduit in concrete wall.

After hearing that i seriously considered just gluing a piece of plywood over it and calling it a day. 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. I considered a lot of options. Knock away the cracked and crumbling concrete around the hole.

4 scoop up about cup of prepared mortar mix. If necessary fill the gap in layers of cement to build up the area slowly. 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. You want the concrete surface in each hole to be perfectly.

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.
