Frequently Asked Questions
Does underpinning stop further cracking?
Underpinning is designed to stabilise a structure and prevent further movement, which typically stops cracks from worsening. However, it may not close existing cracks. Once the structure is stable, cracks can be repaired and monitored to ensure no further movement occurs. In some cases, additional reinforcement or repairs may be recommended.
Is underpinning covered by insurance?
Most home insurance policies do not cover the cost of underpinning unless the foundation issues are caused by a sudden, insured event like an earthquake or burst pipe. However, some policies may cover damage resulting from foundation movement. Always check with your insurer to understand your coverage and get professional reports if making a claim.
Can underpinning be done on a sloping block?
Yes. Underpinning can be carried out on homes built on sloped land, although it may require specialised equipment and techniques. In these cases, screw piling or mini-piling is often used to reach deeper, more stable soil levels. A structural engineer will assess the best solution for sloped sites.
