Concrete Crack Repairs — Rout & Fill Repairs Before Resin Flooring
Untreated cracks in a concrete substrate track straight through the resin floor above them within months. F Wilding Ltd carries out specialist concrete crack repairs UK-wide — routing, filling and reinforcing cracks so the finished resin floor stays intact for its full service life.
What is crack repairs?
We rout out the crack to a defined profile (V-cut or U-cut), vacuum-clean, and inject / trowel a flexible epoxy or polyurethane resin filler. Where structural crack reinforcement is required we insert stitching bars across the crack before filling.
Where and when we use it
Live cracks tracking through existing resin floors, shrinkage cracks in new-build slabs, cracks around expansion joints, cracks at bay junctions in old slabs.
Key benefits
What makes crack repairs the right prep method for the right job:
- Rout & fill with flexible resin
- Stitching bars for structural reinforcement
- Fast-cure options for live sites
- Full compatibility with resin floor above
- Prevents crack propagation into finished floor
Standalone or included in a resin flooring install
We carry out surface preparation as a standalone service for main contractors and other resin installers, and as a fully integrated phase of our own supply-and-install projects. Nationwide plant, direct labour, HEPA dust extraction and out-of-hours access as standard.
Frequently asked questions
Will the crack come back through the resin floor?+
A correctly routed, filled and (where required) reinforced crack should not track through. Where a slab is moving significantly, we install expansion detailing rather than a rigid fill.
Can you work around a live operation?+
Almost every project we run is on a working site. We phase installs by bay, aisle or zone, work nights and weekends where required, and specify fast-cure MMA or polyaspartic systems on jobs where a single continuous shutdown isn't possible.
Do you cover the whole UK?+
Yes. F Wilding Ltd is Essex-based but the majority of our contracts are outside the South East — London, the Midlands, the North West, Yorkshire, the North East, Wales, Scotland and the South West. Travel, accommodation and out-of-hours access are priced into every quote.
