WHY DO CONCRETE FOUNDATIONS CAST VERY RECENTLY START CRACKING?
The chief reason for a cracked slab, or cracked foundation wall is soil movement. Earth can sink under a foundation for several reasons, including insufficient compacting and voids being created by underground water flows. Conversely, certain soils become so expansive when wet that they swell enough to lift and crack a foundation. Cracks can also be caused by incorrect cement mixture, lack of sufficient reinforcing wire or bars, or poor site preparation. If it’s a new foundation, call the contractor and say you want it done right. Before it’s over, you may end up calling a soil engineer and structural engineer.
