Concrete Floor Repair & Resurfacing
A floor is only as good as the substrate under it. We fix the concrete first — crack-stitching, spall repair, joint reinstatement and localised or full resurfacing — so the finish on top lasts.
Where this works
- Cracked / spalled industrial slabs
- Failed movement / saw-cut joints
- Damp or laitance-damaged concrete
- Screed leveling before a decorative finish
- Full slab resurfacing with polymer-modified mortar
How we install it
- 1Diagnose first
Not every crack is structural. We check whether it's a static shrinkage crack, a live movement joint, or something loading-related — the repair depends entirely on which.
- 2Cut & clean
Cracks are diamond-cut into a wide V, blown clean and vacuumed. Loose spalls are cut back to sound concrete.
- 3Fill & stitch
Structural cracks get resin injection and rebar stitching perpendicular to the crack. Non-structural cracks are filled with polymer-modified mortar or resin mortar.
- 4Prime & resurface
The full slab is primed and a self-levelling underlayment or trowel mortar re-establishes level ready for the next finish.
Common pitfalls we prevent
Frequently asked
Do I need to fix the concrete before a resin or microcement floor?+
Yes. Cracks telegraph through decorative finishes if they're not stabilised, and any laitance or unsound patches must be ground off first.
Can you level a very uneven floor?+
Yes — from a 2 mm skim up to 40 mm in a single pour with polymer-modified SLU. Anything thicker needs a bonded screed layer first.
How long before I can install on top?+
Most repair mortars accept a decorative finish in 24–72 hours. SLU is walkable in 2–4 hours and coatable in 24–48.
