Liquid floor screed

Liquid floor screed, pumped and finished by our own crew.

Cementitious self-levelling screed for new builds, extensions and refurbs. Thinner than sand and cement, faster to lay, and the right choice for underfloor heating.

Built for UFH

Flows around pipes with no voids. Better heat transfer, faster warm-up, lower running cost.

Self-levelling

No screed bar, no troweling, no laitance lines. We pump it and finish with a dappling bar.

Less cracking

Lower shrinkage than sand and cement. Bigger bay sizes, fewer movement joints.

What it is

Cemfloor is a calcium-sulphate-free cementitious binder mixed with sand and water on site. It flows like thick custard, finds its own level, and cures into a hard wearing slab in days. We install Cemfloor Therm for underfloor-heated builds and Cemfloor NH where you want a fast-drying unbonded screed.

How thick does it go

Bonded: from 25 mm. Unbonded: from 30 mm. Floating over insulation: from 35 mm. Over underfloor heating pipes: 30 mm cover (so a 16 mm pipe sits in a 46 mm slab). 50 mm is a common depth for domestic UFH builds. We confirm the right build-up for your slab when we review the site.

When you can walk on it

Light foot traffic from 24 hours. Following trades back on the floor from 3 to 5 days. The slab keeps drying for several weeks. Tiling and timber floors need a moisture check first — we can advise on the right timing for your finishes.

What you get from us

We mobilise the truck, the line pump and the crew. We pre-check the UFH pressure, edge insulation, DPM and access. We pump, level, dapple and sign off. You get the batch records, the photos and the customer sign-off in your inbox the day we pour.

Questions we get

Do I need to seal the screed before tiling?

Cemfloor cures with a thin layer of laitance on top. We can sand it back for you, or your tiler can prime over it once it's down to the right moisture content.

Can I lay engineered timber on it?

Yes, once the slab has dried to the right moisture content. The drying time depends on depth, ventilation and the build-up underneath. We can advise on a moisture test schedule when we quote.

Will it work with my electric UFH?

Yes. Cemfloor Therm runs equally well over wet or electric UFH. The cover depth and warm-up programme is the same.
