new block wall question

[bmxdukie]

Folks,
I am in the middle of re doing my garage.
While striping the walls I came across this.
Any ideas on the repair of the block.
I was thinking hydraulic cement after grinding the old stuff out..both sides of course.
Then siding on the outside.
Also, was thinking of saw cutting the floor and filling again to level with new.
Thoughts?
thanks in advance.

Anyone have an idea?

i'm not a concrete wall guy, but here are some questions i'm sure an expert will need answers.

1. is the wall above grade?
2. put a straight edge across the crack... is it bowed inwards?
3. put a level on the wall... is the top tipping in? or out?
4. is water getting in the wall somehow? if yes?, are you in an area that has freeze thaw cycles?

I'm thinking just filling the crack is not gonna do anything except make it look pretty for a year or two.

Buddy,
yes it is above grade.
no it isnt bowed out or in
it is true top to bottom.
No water getting in.
And yes I am in freeze zone.
When I do fix it, I will vinyl side to cover the block and create another measure of water barrier.
Thanks

I do repairs like this all the time at work (I do masonry work). That crack is from the foundation settling, what we would do is cut out the blocks that are cracked in half with a 14" concrete saw and replace the broken blocks and grind out the cracked mortar joints with a diamond blade on a angle grinder and re point the joints. With blocks you cant really use hydraulic cement in the cracks since the blocks are hollow it will all just fall down to the bottom.

Now is a good time to ask I guess. What is the procedure for putting in new blocks in the middle of a wall like that? I guess I am mostly wondering about how to apply the mortar between the blocks as you put them in. Especially on the final blocks.

My cousin is an architect and she has been doing this since a year or two so I guess she will be able to answer this question in more detail.....dunno

Once you chip the old mortar off lay the mortar on you bed joint. Then butter up both sides of the cross joints on the existing block and slide the new block in. We use mortar piping bags and fill up the top were you cant get mortar in with a trowel.

I would break out the floor. Then take a look at the foundation to see what it looks like and repair as needed. Then pour a new floor. With the new floor in and the foundation repaired then I would replace the block around the crack.

Find out how the water is getting in to form the crack so that it can be repaired properly. If you don't find the and repair the source of the water you will still have problems.

Just my thoughts.

What about just taking the cracked blocks completely out and put a man door in that area?
Is that a possibility?

As far as where the floor is all cracked, and the way the rest of it looks, I think I would find someone with a skid-steer, rip out the old, and replace the complete floor.

Would be nice if you could get your hands on some of this stuff!:

We are using a lot of epoxy to repair older existing structures.

As far as the floor goes....... If I had the head room I would just pour a new slab right on top of the old. Old concrete like that makes for some good base.

Look for Kaufmans......... have to order it direct. Won't find it at any retailers. It is the stuff used in commercial applications.

Thanks guys!
I will remove the broken blocks and diamond blade the cracked mortar.
It hasnt moved in the 18 years since I have been here. I know this due to the cement I mixed up and put in the cracks on the other side back then.. I did however miss a few spots that I will get this time.

I was thinking of breaking out the floor but I do have the ability to lift it about 2" max..
