Sincerely speaking, big holes in a cinder block wall are not only unappealing but also may result in the crumbling of the entire wall since, with time, they might end up growing into very larger holes.

How Do You Repair Cracks in a Foundation Wall?
Do you know that the foundation of your home is always under constant stress arising from different forces? The foundation supports the entire weight of the house, including people and objects inside it.
Due to unseen ground shifting and constant exposure to adverse elements of weather such as temperature valuations and moisture changes, holes and cracks may develop on the foundation wall.
- Using a sharp chisel and hammer, chip out all the affected areas around the crack as you make it relatively larger. Hit the chisel to penetrate approximately 1/4-inch under the crack and ensure you slide it at an angle such that the bottom of the break is more extensive than on the surface.
- Using a clean shop-vac and a dry stiff wire brush, clean all the debris and dust from the newly created crack.
- According to the manufacturer’s instructions on the patching mortar packaging, mix an adequate amount that can cover the entire crack.
- Using your putty knife, seal cracks as a whole by adding the newly created mortar.
- Use a clean putty knife to smoothen the patch surface already filled with mortar. Allow enough time for the mortar to fix and dry according to the time indicated on the patching mortar packaging.
- Brush the newly create patch surface using a wire brush since it helps the new cover to blend perfectly according to the rest foundation surface.
How Much Does It Cost to Fix a Large Hole in the Wall?
I remember last year when my family and I relocated to our newly bought apartment, I had previously emailed a well-known contractor to do our garage wall renovation, but to my surprise, he kept postponing until I said enough is enough.
I feared the structural issues of my garage concrete wall would deteriorate, especially that the winter was approaching.
Although the holes had existed for almost a year, these guts at home depot seemed to make fun out of this mess rather than doing the necessary.
I decided to end the differences and slightly swung into action in a beginner-friendly way. The blueprint idea was to fill it using bricks and finally apply a thin concrete coat.
This coat would blend perfectly with the original coating once I paint the entire wall. I collected enough blocks that were lying randomly around the yard with no specific purpose.
Besides, I bought some cement sand, mortar mix, and a trowel at a sum cost of $25. If I had to purchase bricks instead of gathering them, it would have cost me an additional $8 so that the total cost would be $33.
How Do I Fill a Hole in a Concrete Wall?
- Mix the mortar. Start with relatively small batches, especially if you are a beginner, to ensure you get the right ratio and consistency. Besides, it would be easy to mix to attain a clumpy and wet appearance.
- Join the bricks using the mortar and ensure you neatly arrange the blocks as much as possible. Otherwise, don’t worry, since the cement would cover them anyway.
- Apply a layer of well-mixed mortar on both sides of the bricks using a trowel. You can scrape away all the excess mortar that could otherwise be seeping out.
- According to the size you are filling, it can take about two or three hours to fill the entire hole.
- Give it about one or two weeks before you apply the cement. Once you are done applying cement, smooth it using the backside of your trowel to come up with a flat surface.
