This is one thing you don't want to do is do it half Butt (Axx) .They have special tools design for this job . Yes you can rent them at your local Patrick rentals or Some heavy equipment place . But knowing how to use them isn't something you can learn over night.This isn't a cheap job, But I do have a few questions for you.AlwaysTraining said:One side/corner of my house seems to have the earth under the slab eroding away. The gap is almost 2" in one place now, I can reach in and grab gravel stones which I assume that the slab was poured over. I need to stick a yardstick in there and see how deep it goes, but haven't done that yet. It could be that that these stones were added as fill by the previous owner who tried to patch the gap. The slab around and above this area has a few cracks in it too. A drafty cold air can be felt inside the house opposite from this area.
The house has been slowly settling, proof can be seen where the gas pipe enters the house, and the fact that the settling caused the gas pipe to rupture 3 years ago. When I had that repaired I had them allow for some additional settling by caulking the heck out of the opening rather then cutting the siding exactly around the opening. Now you can see that the spot at the repair has settled a bit...hopefully not stressing that pipe too much.
My current ideas are:
0. re-re-re-ensure that water is draining away from the house
1. chip out all remnants of previous quickcrete/expanding foam repair job and re-apply
2. contact professional for an estimate and advice
Any other ideas or experiences?
Correct .... reason me asking about year it was Could be new enough for warranty but it's not .... And you might want to get some estimates as most will come out and give you for free and decide if it's worth paying your deductible which I am sure it would. But also depends how many claims you have entered in the past also if it would or wouldn't be a good idea.whitmo said:I'd contact a professional "pressure grouting" company. Your house is too big of an investment to try some repairs yourself.
It could severly affect your house value and resale.
Indeed :righton: :righton: :righton:seereus said:From what info you have posted, it almost sounds as if your slab has no footings.
Most slab built homes are done on a monolithic pour, wherein the footings and slab are poured at one time.
Another alternative to this method are standard 16" w X 8" deep footings, 8 or 12" block are then normally layed to bring the foundation up to the necessary elevation with the last block being a form block and or a wood form.
If you can actually reach under your slab, something is not sounding right about the construction of your home.
This.those inspectors are basically useless.
I know of one subdivision in Dekalb that has several homes built on such sites. The fill consisted of stumps and logs.seajay said:Maybe more bad news but here goes...
Here in Georgia back in the 80's and early 90's it was a common practice to burry the debris and pack cover it to fill large voids in some of the lots to make them buildable. The debris was made of of downed trees, scrap building materials, mixer wash out and broken brick. The mixer wash out and broken brick are not the big portion of the problem. The wood and paper products are. Over the years the wood and paper turns (rots) into gray matter (dirt) and is no longer as solid as it was when it was thrown into the hole and covered with fill dirt. This causes a sink hole under the house.
That's exactly what I thought. :?seajay said:It looks like someone just tried to conceal it.
That explains problem at my house!!! Although, worst part of it is in middle of backyard and I've been filling it with dirt....seajay said:Maybe more bad news but here goes...

That will all depend on the sonar report. If there is a massive ammount of debris still to rot then probably not. It may need pilons driven to bedrock to jack the foundation back up. I suspect since it is still sinking then this could be the case. That is why it is so important to call every foundation repair company you can find and get as many pro opinions as possible to determine the best way to go about it.seereus said:Based on the pics you have posted, pressure grouting is not going to solve your problem.
