It is not unusual for foundation cracks to form within the first year of new construction, often near windows, corners of the walls or floors or in the longer sections of your foundation. Most are due to foundation settling and are usually not a cause for concern. If cracks become bigger or allow water to seep through, call an expert right away or fill out the form to the right before the damage becomes worse.
If you are unsure about your foundation cracks, monitor them to see if they are increasing in size. Simply use a pencil to mark off and date the ends of each crack. Within a period of time, you will be able to tell if the crack is due to natural settling or if it indicates a more serious problem. Tracking them will also help foundation repair experts determine how they were formed and the best way to fix them. Take a look at the types of foundation cracks below to determine if your foundation crack is a cause for concern.
Usually, a diagonal or vertical crack in the foundation wall is the result of settling in the concrete foundation and is quite common in new construction. Because concrete shrinks while it cures, these cracks are called shrinkage cracks. Frequently you will find vertical cracks in block foundations. Horizontal cracks often indicate a more serious problem.
They are caused by hydrostatic water pressure from the outside of the walls and can lead to a failure in the foundation. Most foundations are designed to handle the pressure of water and soil. Additional pressure due to heavy rains or flooding can create serious horizontal cracks that need to be repaired as soon as possible.
You must contact us as soon as possible if you have a horizontal crack. Fortunately, most foundation issues can be repaired with underpinning solutions and hydraulic lifting.
