Cemfloor is a cement-based liquid screed made in Ireland and pumped across the UK. Unlike calcium-sulphate (gypsum) screeds, it stays cement-chemistry all the way through — meaning it plays nicely with tile adhesives, epoxy coatings and any wet trades that follow. That's why so many Exeter and South-West specifiers now write Cemfloor into their build-ups by name.
We're certified installers. That means our team has been trained by the manufacturer, our pumps and mixes are logged, and every pour is covered by Cemfloor's own product warranty on top of our workmanship guarantee.
Below is the honest technical picture — what Cemfloor is, when it beats the alternatives, and when we'd steer you toward a different mix instead.
Cemfloor vs traditional sand-and-cement
| Metric | Cemfloor vs sand-and-cement |
|---|---|
| Coverage per day | 300–500m² poured vs ~40m² hand-laid |
| Foot traffic | 24–48h vs 5–7 days |
| Flatness | SR1 (±2mm/2m) vs SR2 at best |
| Minimum depth over UFH | 30mm cover vs 65–75mm |
| Shrinkage cracking | Very low — no bay joints vs regular |
| Ready for tile | Days once dry vs weeks |
Where Cemfloor is the right call
We spec Cemfloor by default when the build-up looks like this:
- Underfloor heating on suspended timber or PIR — high thermal conductivity, low cover depth
- Wet rooms, kitchens or basements where a gypsum screed would be a liability
- Large commercial slabs where SR1 flatness is written into the tile spec
- Renovation pours where sand-and-cement can't dry inside the programme
- Anywhere large-format porcelain or LVT is going down without further latex
Cemfloor vs anhydrite / gypsum screeds
Choose Cemfloor when…
- Tiles or wet finishes are going down
- The build has moisture exposure risk
- You want a cement-chemistry sub-base
- Epoxy or polished-concrete top coat
Anhydrite (Gyvlon / Gypsol) is fine when…
- Purely dry residential build-up
- Engineered wood on foam underlay
- Very tight cost-per-m² target
- No wet room in the pour area

If tiles are going down or UFH is in the slab, Cemfloor is almost always the right screed. If it's dry-only residential and cost matters more, anhydrite is fine. We'll tell you honestly which one your build wants.
