Concrete Patch (post #192966)

Hi all,

We have a customer who has a large retaining wall (poured concrete) on their property. The wall probably wasn't installed properly so a lot of it has shifted and moved around over the years. There is a section of the wall that has sheared and is offset by two inches at the top (the bottom is on the same plane). I really did not want to mess with it, as I knew we would not be able to do a good quality job that would last. The homeowner keeps insisting for us to do it. I told her my concerns, and she was fine with that. She just wants it looking better for right now.

Do you have any suggestions for how to do the best quality patch possible? I know it is hard to say those two words together. I figured that I would use the concrete patching compound with the concrete bonding liquid.

Thanks!

You don't say, but I assume this is a poured concrete wall, or perhaps CMU.

Go to the local big box and examine the various patching cements available.  You want something that claims to have some "body" to it so it will adhere to vertical surfaces, and can be build up to the depth you need.  There are usually 8-10 options to choose from, 1-2 of which should sound OK for your purposes.

I would do it in a couple of coats. One to build it up to almost the same height. Score the first coat so the second one has some bite. The second top coat will go on must easier with most of the build done on the first coat.
