The resin injection process
After an assessment, the treatment area is marked out and small injection points are drilled. Resin is injected in stages so the team can control placement, reaction and volume.

Resin Injection for Foundation Repair
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.

Where it is used
Common uses include subsidence repair, void filling beneath slabs, foundation strengthening before extensions, settlement repair and stabilisation around leaking drains or washed-out ground.
Why homeowners choose it
The process can avoid major excavation, reduce reinstatement costs and often keeps properties usable during the works.

Resin Injection FAQs
Straight answers before you book a survey.
How long does resin injection take?
Many domestic projects are completed within one to two days, although larger or more complex schemes can take longer.
Will you dig up my garden or floor?
The method is designed to avoid extensive excavation. Some access or local preparation may still be required depending on the property.
Is resin injection the same as underpinning?
No. Traditional underpinning usually involves excavating beneath foundations and placing concrete. Resin injection improves the ground with targeted expanding resin.
