Cracks in basement wall — Barcelona, Catalonia
Horizontal or stair-step cracks in a basement wall indicate lateral soil pressure or foundation settling that can worsen over time and allow water intrusion. White mineral deposits around the cracks signal that moisture is actively migrating through the masonry. A foundation specialist evaluates the crack pattern and wall movement, installs carbon-fiber straps or steel braces to stabilize the wall, seals the cracks with hydraulic cement or epoxy injection, and addresses exterior drainage to reduce hydrostatic pressure against the wall.
