Road re-levelling in the United Kingdom
Dips, steps and sunken panels in concrete roads, traced to their cause and lifted.
About road re-levelling
What this work involves
Road subsidence is the sinking of the ground or the concrete carriageway above it, and it shows as dips, cracked panels and steps at joints. Leaking drains, poorly compacted trench backfill and soft ground are the usual causes, and heavy traffic makes it worse.
A specialist checks the concrete panels, finds where support is missing and advises whether injecting resin beneath the slab will restore the level or whether the cause below needs fixing first. Give the road type, the length affected and any traffic management limits, and the work is priced from that.
The essential facts in brief
Road subsidence in the UK explained: what makes concrete carriageways sink, how panels are lifted by injection, and how to make an enquiry.

Does this describe your concrete?
- A shallow bowl in the road surface holds water after rain.
- Cracks follow the line of a trench, kerb or manhole, with the surfacing lower on one side.
- Kerbs and channels have fallen out of line and the camber has gone.
- A wheel sinks or drops where a soft patch has opened up under the surfacing.
- Vehicles bounce or scrape on a stretch that used to ride smoothly.
How the job gets done
Site safety
Cones, signage and a safe working zone are set up before the specialist starts measuring the sunken section.
Dip measuring
A straight edge and level record how deep the subsidence is and where the road surface has lost support.
Injection run
Resin is injected through small holes in passes, lifting the surface a little at a time until it matches the road either side.
Reopening
Holes are filled and cracks sealed, and the lane is reopened once the resin has set, usually within the hour.

What road subsidence usually means
A dip has a cause
Road subsidence is the surface sinking because the ground or fill below has lost volume. Common causes are a leaking drain, a poorly compacted trench or soft ground. The specialist looks for the cause before deciding on a lift.
Lifting or rebuilding
A lift suits a slab or pavement that is still sound but has dropped. Where the surface is broken up, a rebuild may be the more sensible route, and the findings say so.
Keeping lanes open
Injection needs small holes rather than a dug-out section, so work can often be done in short closures rather than long ones.

What is road subsidence?
Road subsidence is the sinking of a road surface because the ground or fill below it has lost volume or support. Concrete carriageways show it as dipped panels, steps at joints or cracking across the slab.
Does the cause need to be fixed before the slab is lifted?
If a leaking drain is washing material away beneath the slab, the leak should be dealt with first. Lifting over an active void is a short-term fix. The specialist checks for this and notes it in the findings.
How long is a lane closed during injection?
Injection holes are small and the resin sets quickly, so a lane can often be reopened within an hour or two of the last injection point being filled. The specialist confirms the closure time for your road type.
Is this suitable for a public road or only private roads?
The method is used on both. Public road work needs the appropriate traffic management and any highway authority permissions. The specialist confirms what is needed before work starts.
