London

London foundation enquiries often involve southwestern Ontario clay and frost heave, with issues such as frost heave, wet basements, bowing walls and clay settlement.

Housing and foundation context

In London, southwestern Ontario clay and frost heave means movement can show up as cracks, sticking doors, uneven floors or bowing basement walls — especially where drainage or moisture around the foundation has changed.

Common foundation types in the area include full basements, concrete block and poured walls, some pier systems. Our crews assess soil conditions, drainage and structural movement.

Guidance and next steps

Follow building-department and geological-survey guidance where published. Photograph cracks and sticking openings, note when movement started and keep drainage clear of the foundation.

We help you request an on-site foundation assessment.
