Why we pour Cemfloor
We're manufacturer-certified Cemfloor installers, trained by the maker, with every batch logged. The products we lay are Cemfloor CT-C30-F6 and Cemfloor Therm. Made in Ireland and pumped like any liquid screed, it keeps a cement binder throughout — so it gets on with tile adhesives, epoxy coatings and whatever wet trades follow.
We record the product, mix and installation details for each pour and provide clear aftercare guidance for the floor that follows.
Build-ups where it earns its place
- Underfloor heating over suspended timber or PIR, where you want low cover and fast heat transfer.
- Wet rooms, kitchens and basements — places a gypsum floor would be a liability.
- Commercial slabs with SR1 written into the tiling spec.
- Renovations where sand and cement simply won't dry inside the programme.
- Large-format porcelain or LVT laid without an extra latex layer.
Thin over the pipes
Over wet heating we need just 30mm above the top of the pipe on a bonded build, or 35–40mm unbonded, against 65–75mm for traditional sand and cement. Less mass to warm means a more responsive floor. We confirm the exact figure on survey.
Drying, honestly
Allow roughly a millimetre a day for the first 40mm, slower beyond that. In normal conditions a 50mm floor is typically under 75% relative humidity inside three weeks. You can walk on it after 24–48 hours, and there's no compulsory laitance sand for most mixes — just the manufacturer-approved primer per the datasheet.
Choosing between the two
Tiles, water, or heating in the slab? Go cement. A purely dry residential floor under engineered wood where cost per m² leads? The anhydrite liquid screed may be the better fit. Deeper product detail sits on our Cemfloor screed page; prices and survey on screed floor installation in Exeter.
