TL;DR
Differential settlement is the uneven sinking of different parts of a foundation, one corner dropping while the rest holds, which twists the structure above and produces stair-step cracks in brick, doors that rack out of square, and floors that slope toward one wall. It is far more damaging than uniform settlement because of the distortion, and its usual drivers are poorly compacted fill, expansive clay cycles, eroded soil from drainage problems, or tree roots drying the ground.
What it means
Differential settlement is the uneven sinking of different parts of a foundation, one corner dropping while the rest holds, which twists the structure above and produces stair-step cracks in brick, doors that rack out of square, and floors that slope toward one wall. It is far more damaging than uniform settlement because of the distortion, and its usual drivers are poorly compacted fill, expansive clay cycles, eroded soil from drainage problems, or tree roots drying the ground. Repair quotes typically center on underpinning with push or helical piers, with elevation measurements documenting the movement.
