I know it’s not supposed to be able to raise a house foundation but it did.
All the jacking system guys quoted 36k to 50k to secure a foundation. They also said they wouldn’t get it lifted back to level.
Well I used hydraulic jacks on steel plate under the footings in 3 different locations and put upward pressure on the house then used the spray foam on the interior floors and raised one side an inch and the other side three inches.
The cracks in the drywall over the windows closed. Removed jacks and backfield with dirt and packed down.
I used 4 kits, 6 20 ton Hydraulic jacks, at a cost of 2500 dollars.
