About resin injection for subsidence
What the work covers
Resin injection for UK properties, explaining how expanding resin fills voids and firms up ground beneath foundations with minimal disruption to the building.
Resin injection stabilises the ground beneath a foundation by pumping an expanding resin through small holes drilled into or beside the footing. The resin fills voids, binds loose soil particles together and can lift a settled slab back towards its original level. Because there is no significant excavation, the process causes far less disruption than traditional underpinning methods.
This approach suits situations where voids have formed under a concrete floor or strip footing, often after a drain leak has washed fine material away, or where the soil immediately below the footing has loosened. It is not suited to every subsidence case, and a structural assessment is needed before a method is chosen. A specialist will review the ground conditions and the evidence of movement before advising whether resin injection is appropriate. A free quote is available once that review is complete.

Process steps
How the repair process unfolds
Ground probing
The specialist tests the ground beneath the slab or footing to locate voids and map where weak soil sits.
Hole drilling
A grid of small-diameter holes is drilled at spacings calculated to reach the voids identified below.
Resin injection
Expanding resin is pumped through each hole in controlled stages while level readings monitor any movement of the structure above.
Seal and record
Each drill hole is filled and finished flush, and a written record of injection volumes and final level readings is produced.
Signs that resin injection may be the right solution
Does your property show these signs?
- A section of pipe beneath a concrete slab has collapsed and full excavation is not practical
- Ground movement that a structural engineer links to cavities or disturbed material beneath a slab or footing
- A listed or historic property where conventional mass-concrete underpinning would damage original building fabric
- Cracking concentrated at one or two corners rather than spread evenly across the structure
- Access to the affected area is too restricted for conventional excavation equipment
- Ground investigation results showing the affected zone is shallow enough for injected resin to reach
What's involved
What to consider before choosing resin injection
Where the method is most suitable
Resin injection suits properties where settlement is caused by voids or loosened subsoil rather than a structural failure of the footing itself. It is often chosen where access is tight, where open excavation would disturb neighbouring structures, or where the building is occupied and surface disruption needs to be kept low.
Ground type and suitability
Resin injection works well in loose sandy or silty ground and where gaps have opened up beneath a concrete slab. Where deep shrinkable clay is still losing moisture, a specialist may suggest a different approach or pair resin injection with a second method. Ground conditions are confirmed before injection begins.
Monitoring during injection
The specialist monitors any structural movement throughout the process using levels. Resin is injected in measured increments, lifting the structure to the target level without overshooting, since going too far creates problems comparable to the original settlement.
Where resin injection is not suitable
Resin injection is not appropriate for severe foundation failure where load-bearing walls have shifted substantially. A broken drain or active clay shrinkage must be remedied before or alongside any lifting work, otherwise movement will return. A free quote will set out whether the method suits your property.
