Diagonal stair-step cracks in brick or block foundation walls — Lodz, Łódź
Diagonal stair-step cracks that follow the mortar joints of a brick or block foundation wall are a classic sign of differential settlement — one section of the footing is sinking faster than the rest. Lateral soil pressure, poor drainage, or shifting clay can accelerate the movement. Left unchecked, the crack widens, allowing water intrusion and threatening structural integrity. A foundation specialist assesses the crack pattern and soil conditions, then stabilizes the wall with helical piers, wall anchors, or carbon-fiber reinforcement before sealing and waterproofing the repair.
