You need deep foundation support.  For example, many bridges are built on top of wide-diameter pilings that are pounded into the ground.  This gives the bridge more support so that it won’t sink into the ground, or slide down a hill.  We use small-diameter pilings to support houses in this same manner.

Epoxy is a liquid material that we squirt into cracked concrete.  We “pressure inject” this liquid using a handheld Epoxy gun.  The liquid then hardens to provide a “sealed” crack.

You may see cracks in the walls, ceiling, or floor (slab); You may notice a slope in the floor; The windows and doors may not function properly; The concrete around the perimeter may be breaking apart; Your eggs slide to one side of the pan
