Underpinning is the process of strengthening and stabilizing an existing foundation by adding new support beneath it. It helps protect the structure and improve long-term stability.
A weak or moving foundation can cause serious structural problems. Underpinning helps stop further settlement, supports the building safely, and protects the value of the property.
You may need underpinning if you notice wall cracks, uneven floors, sticking doors or windows, sinking areas, foundation movement, or signs that the property is no longer sitting level.
