WHY DO WE HAVE
It is not unusual to see foundation problems in the Dallas-Fort Worth area, these are caused by moisture variations during cool wet winter or hot dry summers.
As soils dry they shrink and consolidate. A foundation usually settles during the summer months, especially along the outer perimeter.
Usually the winter months are wet, so the expansive clay soils tend to swell and rise the foundation. If the soils get too wet, soil strength will become too low to support the load of the house and the soils will deform and the house will settle.
