When resin may be suitable
Resin injection may be considered where weak or voided ground beneath the foundation needs improvement and access can be achieved by drilling small injection points.
Modern foundation repair
A Less Disruptive Alternative to Underpinning
Traditional underpinning has its place, but it can mean trenches, spoil, delays and major reinstatement. For suitable ground movement problems, resin injection can provide targeted stabilisation with far less disruption.

When underpinning may still be needed
Some deep, severe or complex structural problems may still require engineered underpinning or other solutions. The right method depends on survey findings.
A practical first step
If you have been told you may need underpinning, a resin injection assessment can help confirm whether a lower-disruption option is realistic.

Resin injection is a modern ground improvement method that places expanding structural resin into weak or voided soil zones below a building. It is fast, targeted and often avoids large-scale excavation.

Alternative to Underpinning FAQs
Straight answers before you book a survey.
Is resin injection cheaper than underpinning?
It is often more cost-effective for suitable problems because it reduces excavation, spoil disposal and reinstatement, but every property must be assessed.
Will building control accept resin injection?
Acceptance depends on the project and supporting engineering information. We can work with your professional team where approvals are needed.
Is it guaranteed?
Eligible works can be supplied with guarantee documentation. Specific guarantee terms depend on the scheme and property conditions.
