patching holes in basement cement block wall

jhiner

I removed a bunch of old paneling and furring strips in my basement, and in the process created several holes / nicks in the blocks. I can post pictures, but basically they vary from 1/2" to maybe 2" depending on how much got pulled out when I was removing the nails. None of these penetrate all the way through to the cavity in the block. Is hydraulic cement appropriate to use in this situation to patch these holes?

I also have a couple larger holes. One is about 3x4" and it was busted out to install an outlet. I planned on filling in the cavity with something (maybe that expanding foam stuff) to use as a backing and then using hydraulic cement as well. There are also a couple 1-2" round holes that penetrate through to the cavity of the block, and I was going to use the same method. Is this the way to go?

Finally, I have some cracks where the floor meets the wall, and was also going to use hydraulic cement there. Is there something better? I have read some discussions about different products, such as crack filler, and "Silicone Waterproof Concrete & Masonry Caulk", but am completely clueless. I appreciate any advice! Thank you!

i have never used hydrolic cement but i do know that sika 224 works wonders it is perfect for patching holes because it sticks very well and is strong when mixed correctly with the "milk" it dosent crack and dries fast...google it for details

Thanks, I'll check it out. It doesn't look like Lowes or Home Depot carries it, though.

I also wonder if it's even necessary to patch the surface holes, and if I should just concentrate on patching the major holes that go all the way through to the cavity.

Edit: The main product I had been looking at was DRYLOK Fast Plug Hydraulic Cement

Is the wall painted? If not holes that small can be easily patched with regular mortar. Buy a bag of "Mason Mix" from the box store. It is made by Quickcrete.
