When Dolton self-builders specify UFH, the screed is what makes the system efficient. We pump Cemfloor Therm directly around your pressure-tested pipework for full encapsulation.
For Dolton UFH builds the typical sequence is: insulation board down, pipes clipped and pressure-tested, edge insulation in place, then we pump and level in a single visit.
Most of our Dolton jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Dolton sits Barnstaple (18 mi), and we work the surrounding villages on the same week's diary.

Built for Dolton rural self-builders and farms
Dolton sits rural — barn conversions, self-builds, agricultural sheds, equestrian floors. Access is usually fine, but power and water on site need confirming up front. We do that at the site visit.
Underfloor Heating Screed in Dolton — how it works
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Dolton renovations.
We pour Cemfloor Therm liquid screed over your UFH pipes at 50mm above pipe (typically 65-75mm total over insulation), giving full pipe encapsulation, fast thermal response and a finished surface flat to SR1.

Common Dolton build questions
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
When can I switch the underfloor heating on in Dolton?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Dolton clients to the schedule.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
Can you screed over wet UFH and electric UFH?+
Yes — Cemfloor Therm encapsulates both. Electric mat systems usually take a thinner cover; wet pipes need the 50mm minimum.
