What is “spalling” and what causes it … Most common, spalling occurs at bricks, but may also occur at masonry, concrete, natural stone and limestone. What causes spalling is moisture / water. When moisture penetrates the brick to the point that is too much for the brick to handle, the moisture forces the surface to peel, pop out, and will begin to break apart. Other causes may include varying weather conditions, dripping water, faulty mortar, expansion and cracks when freezing occurs. Like spalling brick, loose brick can also be causing the structure to move and or settlement of the structure, leaving holes in the mortar. These holes allow water to penetrate the wall and can loosen the brick. Common areas for loose bricks include chimneys, around mortar joints, faulty gutters, doors, windows, and around the foundation. Here are some examples of brick spalling.
