Cracks that appear along mortar joints or stair-stepping cracks that are present in the corners around windows and doors are a sign of foundation settlement. If the cracks widen on one side or the other, this is typically an indication of foundation settlement.
These cracks within the mortar are generally caused by a few factors. As concrete walls cure, they shrink as moisture is absorbed within the concrete itself. Foundation settlement in this case can be caused by weaker soils under the foundation, water erosion from a spring or high-water table, soil shrinkage due to drought or due to loss of water to tree roots or other vegetation.
Do I Need to Fix This?
In these situations, it is best to have the cracks in mortar looked at further by a trained professional. Small cracks that are less than 1/8” typically have little or no effect on the structural integrity of the wall. Larger cracks, and wider cracks may require attention. A single mortar crack, or a series of mortar cracks may be an indication of a larger issue with a compromised foundation.
The solution is to support the foundation below the active soil layer by installing Grip-Tite Push Piers or Grip-Tite Helical Piles. The piers or piles will act to secure the home’s foundation in stable soils unaffected by the overabundance of water, or the lack of it. Our professionals will install Grip-Tite foundation brackets and piers to support your foundation and restore the structural integrity of the home’s foundation.
