Support before stress becomes damage

Foundation Strengthening for Homes and Extensions

Older homes, new loft conversions, extensions and changed loads can expose shallow or weak foundations. We strengthen the ground supporting the footing so the building has a more reliable base.

FAQ

Foundation Strengthening FAQs

Straight answers before you book a survey.

Can you strengthen foundations before an extension?

Yes, where the existing foundation or supporting ground needs improvement, resin injection may be considered as part of the engineering design.

Will I receive documentation?

We provide clear records of the work carried out and can support documentation required by engineers, insurers or conveyancers.

Is a survey needed first?

Yes. A survey helps confirm access, foundation type, visible damage, drainage concerns and the most appropriate treatment plan.
