Hydrostatic pressure exerts force against the exterior foundation wall and becomes more severe further underground. Hydrostatic pressure from sub-grade settlement, horizontal loading from the structure above and backfilling can also cause uneven stresses and lead to cracking. These are caused from foundation movement due to poorly prepared foundation footings, improperly placed or omitted steel reinforcement. Settling cracks can increase in size to 1/4" or more or stop completely. These will likely occur shortly after construction, extend down the entire length of the wall to the floor and possibly be the site of water infiltration. These are often present in poured walls, wider at the bottom and continue to increase in length and width. Shrinkage cracks can be sealed to prevent water entry by chipping out the crack, filling with masonry patching compound, epoxy, polyurethane foam or other sealants.

There is a significant risk of wall collapse, so contact a professional immediately.
Caution should be used if the bond courses are broken. However, brick wall cracks will not be caused by shrinkage and may indicate a structural or support problem. You can expect to see more as the foundation dries completely. Shrinkage cracks usually don't require any remediation work or structural monitoring in poured or block walls. Brick walls don't normally shrink but expand forever. Temperature swings consistent with the change of season can also cause the concrete to expand or contract to cause cracking.īlock foundation walls - Shrinkage cracks are generally uniform in width, form at the center of the wall and are also caused by curing and temperature variations.īrick walls - While bricks are no longer used for present-day foundations, older buildings may still have structural brick walls in place to support the first floor. Poured concrete foundation walls - Shrinkage cracks can be caused by poor mix, rapid curing, improper or omitted steel reinforcement. Cracking relieves this stress during curing. As concrete shrinkage occurs, it will develop internal stresses. These cracks can be caused at original construction due to several factors, depending on the type of construction. Shrinkage occurs as concrete cures, which is a chemical reaction and affected by the amount of water, aggregate type, humidity, Portland concrete, groundwater, sun exposure, temperatures and other conditions.

Shrinkage cracks almost always extend through the full depth of the foundation wall so may be a source of water entry. They'll usually be less than 1/16-inch wide and show up as hairline, sporadic, random, and discontinuous cracks or a combination of all types in the wall. Shrinkage cracks will appear under basement windows, above doors, at step-down areas and in the center of a long wall if control joints were not used. They will range in length and will stop before reaching the bottom of the wall. These will be wider at the top and get smaller as they travel vertically down the wall. You'll notice these are generally uniform in width or sometimes, less commonly, appear as V-shaped cracks. Now you’re ready to inspect and evaluate your own foundation to determine the best course of action. An easy reference is: 1/32” = width of a credit card, 1/16” = width of a nickel, 1/8” = width of two nickels. Measuring with a tape or ruler can be difficult for anything less than 1/4”. It’s important to accurately determine the size of the crack.

There are many types of foundation cracks that can occur, signaling some type of damage, but repair work will vary based on the type of foundation material plus the size, shape and location of the crack.
