Do Tree Roots Cause Foundation Cracks in Clay Soil? Distance and Settling Factors

Two lime trees (10m tall, 8m from wall) and one maple (9m tall, 7m from wall) on clay soil. Owner asks if they cause wall cracks.

Too Far to Matter

All are well beyond the distance where roots affect foundations.

Likely Cause: Settling

• Grading from new construction.
• Soil drying excessively under foundation.
• Erosion washing soil away.

Investigate these if cracks are serious.
