How to repair sinking house foundation? My mom's house is built on a concrete slab (no basement or...
My mom's house is built on a concrete slab (no basement or crawl space). We've notice for quite a few years very soon, that around the perimeter of the inside of the house, here is about a 1 to 1 1/2 inch 'ledge'. I diagnosed it as a sinking foundation.
We have a contractor out (he was extremely cocky), and he confirmed, near a $20,000 price tag to hold the house pumped up (approx. 17 plugs). My mom was angry near this guy's attitude, and now won't own any work done until she has an contrive confirm what's already been said.
I'm getting desperate here! The chimney is pulling away from the house, one of the exterior walls is starting to bow. The walls are cracking, and one can singular imagine what's going on beside the ceilings--they're all suspended. Selling the house for what the house is worth is NOT an option. This wants to get fixed-the right way-and I want some advice. What giving of an engineer do I look for? How much 'should' this cost? Any other planning?
Get the contrive. I would look at moving the house onto a new foundation as it sounds resembling you have a soil problem.
I would approaching to see the place so I could tell more.
Is it the floor explicitly sinking or is it the walls.
It can only sink so far. Cement is extremely cheap.
If you could put voice 1 1/2 inches of cement over all the existing floor, would that solve the problem?
Mix cement contained by any size container and spread it level.
You can gain a lazer level at Home Depot and conclude up with height floors for a few hundred dollars. Reset the doors if you have to. This is something you can do yourself somewhat at a time. Don't let the inspector see it.
Answers: Depending on what your soil conditions are this could be expensive to fix. Unless bedrock is within a few foot of the surface it could cost at least $20,000.00.
You don't read out what your location or square footage is so I will answer in common terms.
It isn't unusual to see fringe and loadbearing footings settle more than the floor. The buildings weight is concentrated at these places. If the foundation is watered down then the footings will plunge disappearing the floor higher, usually a crack appears around the boundary at the walls.
If new piers are indecently placed on the same lacking foundation (for example not deep enough) the untried piers only put in weight to the structure. You could spend profusely of money and only net things worse.
Your mom has obedient instincts. You should contact a "structural engineer". The cost to repair the resulting damage to the structure if allowed to progress could be focal.
There should be a geo-technical or soils report done to determine the soil conditions and depth of suitable foundation.
Based on the soils report the structural engineer can draw up plans to do the livelihood properly.
good luck
