Cracks in brick are commonly caused by differential movement in a buildings foundation but did you know brick can also demonstrate foundation movement in other ways?  One less well known indicator is identifying curved brick mortar lines in the brick courses by sighting along the brick mortar lines.  Quality brick installations are typically installed using a string line every few courses during construction to keep the brick courses straight.  Sighting for curvature can tell you if a brick wall has moved up or down along its length.  This helps to understand how a foundation is performing and where to look for additional damage to confirm this observation.  Want to know more?  Stay tuned, or send us a question.
