Home re-levelling with resin injection in the United Kingdom
Sloping and cracked concrete floors inside houses, checked for cause before any lifting.
About home re-levelling with resin injection
What this work involves
Inside a house, a concrete floor that has dropped away from the skirting, sloped across a room or cracked along its length points to ground movement below. Extensions, conservatories and older ground-bearing slabs are the places it shows most often.
Before any lifting, the specialist looks at whether the movement is still going on and whether the cause, such as a leaking drain or shrinking clay, has been dealt with. Where the slab alone has settled, injection can lift it with little mess and no new floor. Describe the room and what you see and the work is priced to match.

Does this describe your concrete?
- A hall or extension floor has dropped against the rest of the house and left a gap behind the skirting.
- The porch or conservatory base has sunk away from the wall it was built against.
- Slab cracks show through the floor covering, which has started to lift.
- Internal doors rub on the floor or no longer swing freely.
- A gap has opened between the slab and the wall.
How the job gets done
Room survey
The specialist measures how far each room's floor has dropped and notes where gaps show at skirtings and doors.
Crack readings
Gauges and photographs record whether the cracks are still moving before anything is injected.
Floor raise
Small holes are made and resin is injected in steps, with levels read after each one until the floor is flat.
Making good
Holes are filled and the floor is cleaned, and doors and skirting are checked against the new level.

Floor slabs and the signs of ground movement
Slab or structure
A sunken concrete floor inside a house can be a localised void, or it can point to wider movement in the building. The specialist notes cracks in walls and door frames and says when a structural engineer should be consulted.
Levelling over a sound floor
If the slab is stable but uneven, a primed self-levelling layer may be enough. Priming helps the compound bond and stops the concrete drawing water out of it too fast.
Living in the house
Injection holes are small, and floor coverings can usually be lifted in the working area only. The specialist explains what needs moving before the visit.

Unsure which fix applies? Browse the services
Is a cracked internal floor always a sign of subsidence?
Not always. A crack across a ground-bearing slab can come from shrinkage, poor construction or a localised void rather than ongoing ground movement. The specialist looks at the crack pattern, any movement in walls and door frames, and checks whether the floor is still moving before advising on a repair.
Do I need a structural engineer before calling about a floor?
Not necessarily. If the cracks are confined to the floor and there is no sign of movement in the walls, the specialist can assess what is happening. Where wall movement is also present, the findings will say whether a structural engineer should be consulted.
How much of the floor covering needs to come up?
Only the covering in the area being treated needs to be lifted. The specialist tells you which section to clear before the visit. Floor coverings in other rooms are left alone.
Can a self-levelling compound be used instead of injection?
A self-levelling compound works on a slab that is stable and just uneven on its surface. The slab must be primed first so the compound bonds properly. Where the slab itself has dropped, injection raises it; a compound applied on top of a sunken slab will follow it if movement continues.
