mudjack?

[merl]

I have an older brick house, a corner has settled and there is a ~1/2 gap in the brick (outside) at one corner.
Obviously I don't want this to get any worse. I want to nip this before any brick above the floorline cracks.
Can a foundation be pushed back up with mudjacking? Can it be stabilized and tuckpoint'd?
I'm a EE, this is a bit outside my training. Anyone out there have any advice?

knock it down and start over

mudjacking is for lifting slabs, you an engineer to figure out the cause

Colorado?
Bentonite caused foundation to shift.

I'm not an engineer, just a native.

One of the buildings in Northglenn I used to do facility maintenance on was mud jacked 3 times due to the floors and walls settling. It still to this day has ongoing problems. I'm not an expert but it certainly didn't help there and was not cost effective from what I could see.

I'm not familiar with all of the techniques they use, but foundation repairs are definitely called for. I grew up on the gulf coast of Texas where everything is basically sitting on swamp land so settling is inevitable.

Call several people out to give you estimates. Sometimes different foundation people will recommend different methods of repair. I know the methods that worked best for me involved concrete pylons being poured under the home that were really deep.

This.

My parents had trouble with one corner of their house settling, so they had it mud-jacked (It was built in 1960). Ten years later the problem was back. Mom had a contractor come out and put pylons down to the bedrock which were then bolted to the foundation. In the corner where the problem was, it was about 30 feet to bedrock. Just a few feet in either direction it was only about 12 feet. Apparently there was an underground spring at that corner.

I think there ended up being 5-7 pylons poured. It cost mom around $45,000.
