Garage floor re-levelling in the United Kingdom
Garage floors that have dropped or cracked, lifted from inside through small holes.
About garage floor re-levelling
What this work involves
A garage floor that has sunk leaves a gap at the door, a slope that sends water inwards and cracks across the slab. In older garages the slab is often thin and was laid over little sub-base, so it takes little for it to move.
The specialist checks the floor and the walls for signs of wider movement, finds the void beneath the slab and advises on lifting by injection. Work is done from inside through small holes and the garage can be cleared and used again soon afterward. Tell us the garage size and the drop and a price follows.

Does this describe your concrete?
- The floor slopes away from the door and water runs in after rain.
- The slab has pulled away from the walls and left a gap along the edge.
- The garage door will not close fully, or the seal sits unevenly on the floor.
- A crack crosses the floor and one side is lower than the other.
- A car or workbench sits at a visible tilt.
How the job gets done
Door and floor
The specialist checks how the door closes and measures where the floor has dropped away from it.
Gap probing
Test holes show whether the slab has a gap beneath it or sits on soft fill.
Slab raise
Resin is injected in steps while levels are read, so the floor comes up without cracking.
Door test
The door is opened and shut again, and any remaining gap or slope is recorded.

Sloping garage floors and door sills
Where the floor has dropped
Garage slabs are often poured on thin fill and can sink at the door end or along a wall. The specialist measures the floor across several points to show the slope.
Door and sill clearance
If the slab at the door has dropped, water can run inside. Lifting it brings the sill back up, and the specialist checks the door travel afterwards.
Contents
Injection from the surface keeps work to a small area, but cars, shelves and stored items in the lift zone need moving first.

Unsure which fix applies? Browse the services
Does the garage floor have to be completely empty?
Only the section being lifted needs to be clear. If one end of the floor has dropped, the car and any items stored in that zone need to be moved, but the rest of the garage can stay as it is.
What if the slab is cracked as well as sunken?
A slab that has dropped often cracks at the same time. Cracks do not prevent lifting provided the concrete is still in large pieces. The specialist records crack widths and positions, and notes whether any crack is wide enough to need filling separately.
How long before the car can go back in?
Resin sets quickly. Most garage floors are ready to take the weight of a car within a few hours of the injection finishing. The specialist gives the actual wait for the product used.
Will the door seal gap close after lifting?
Lifting the slab at the door end usually reduces or closes the gap between the slab and the door bottom. The specialist checks the door operation after the lift and records whether the gap has been resolved.
