what wouuld be the cause of this and what can be done to remedy the situation?if possible how costley would this be to fix.
this is an inside wall from a 2 car garage.
Answers:
twood has hit it, it is a very costly problem. The house would have to be jacked, then the wall removed and replaced, then it needs to set up THEN maybe if all is well your house can be dropped. App. time 4-5 months ( in best scenario). Cost depends on the size. If you have a warranty with your house I would be checking into that. Otherwise the rest is your decision to fix it or leave it. Worst case the wall could slip your house falls in. Best of luck to you.

unfortunately,,,,concrete cracks...if you could figure out a way to stop it,,,,you would be rich....if you have epoxied it,,and it is still cracking,,,the number one cause for concrete failure is poor preperation,,,sub-base, not much you can do either live with it,,,or remove and replace,,,,first decide just how detrimemtal this crack is and if its (1) worth worrying about,,(2) if its worth fixing.tony

Just get more epoxy and fix it. 2 or 3 mm every 4 years. Fix it once every 20 years.
epoxy is only a quick fix that will be repeated every so often. If the house is still settling then thats the real problem. Fix the settling and the crack will stop too. That will mean digging it up and putting the correct foundation under the wall.
If the crack is not going through the foundation into a living space, don't waste your money on more epoxy. The purpose of epoxy is to keep water out, not stabilize the structure.
Mark the crack with a small grid, using a permanant marker, so it will be obvious if you have more changes occur. Continued movement may require underpinning (repouring of the footing), which can be a fairly pricey repair.
In the meantime, make sure you are maintaining a good drainage pattern on the house exterior (soil sloping away from foundation, eavestroughing installed and draining 6 to 8 feet from house). If you are getting excessive water collecting near the foundation, it can cause soil softening and the type of damage you are describing.
I am assuming this is a vertical crack. A horozontal crack would be a different ballgame.
