How to make Masonry Crack Repairs

Causes of masonry cracks can result from variety of factors, including settling of the foundation, ground movement, temperature changes, and moisture. In addition, inadequate design or construction of the masonry can also lead to cracking. It is important to have a professional inspect any cracks that you notice in your masonry to determine the cause and develop a plan for repair.

Engaging a structural engineer is the most effective way to diagnose causes of masonry cracks, as engineers can quickly survey the building and arrange tests to effectively understand the underlying risk factors, before considering any repairs.

There are several different methods that can be used to repair masonry, depending on the type and extent of the damage. Some common methods include:

1. Patching: This involves filling small cracks or holes with mortar or a similar material.

2. Rebuilding: For more extensive damage, it may be necessary to remove and replace the damaged masonry.

3. Grouting: This involves injecting a grout material into the cracks or voids in the masonry to strengthen and stabilize it.

4. Stitching: This involves drilling holes into the masonry and inserting metal pins or bars to hold the masonry together and prevent further cracking.

5. Anchoring: This involves attaching metal anchors to the masonry to provide additional support and prevent further damage.

It is important to consult with a professional structural engineer to assess the masonry building and structural risks factors, before determining the best method for repairing your specific situation. Especially if ongoing movement makes particular masonry repairs ineffective, before considering the cause of the problem.
