Underpinning

Underpinning existing residential or commercial buildings is usually required due to subsidence and sinking footings.

Depending on the situation, we will underpin using screw piles, reinforced concrete piles, or in some rare cases, driven steel. Generally using a corbel system under the existing footing, we can lift a house as required using a series of hydraulic rams attached to the corbels.

Access can be problematic when underpinning existing buildings, so Spiral Drillers now has miniature rigs that a perfect for tight or difficult sites.

If you are unsure, give us a call on 0800SPIRAL and we can help you begin the process.
