All masonry walls will move, primarily due to changes in temperature and moisture content. Additional movement might occur from structural concrete frame moisture loss or creep, and elastic deformation. Restraining these movements may cause stress cracks to develop in the wall. The type of movement will depend upon materials, construction, and wall configuration. The primary […]
