Underfloor Heating Screed in Farnborough

Wet underfloor heating in Farnborough can be screeded in pumped liquid or hand-laid sand and cement; either way we encase the pipes fully and leave you clear heat-up advice at handover. Pipework and its pressure test belong to your heating engineer, and once that is done we check the insulation and perimeter edge strip, then screed to the required depth. In Farnborough this usually means a heated extension on a post-war house, or a floor replacement where the slab is broken out anyway.

Heated floors in Farnborough extensions and replacements

Adding heating is easiest when the floor is new. An extension on a post-war semi or terrace in Farnborough is built with its own insulated base, so there is room for the pipes and a full screed. The same applies when the old slab is broken out: once insulation and a membrane go in, the pipes can be clipped down on top before screeding. Detached houses, 20% of the town's homes, can have larger rooms where a single heated zone makes sense.

The two screeds behave differently over pipes. Pumped liquid flows into every gap round the pipes, so there are no air pockets, and with at least 25mm over them the floor normally totals 45 to 50mm. Sand and cement has to sit roughly 45mm above them, making a deeper floor overall. Thinner screed warms up faster and uses less height, which is often the deciding factor in a retrofit where every millimetre counts.

Where heating is being added to part of an existing ground floor, the height problem gets sharper. The new heated floor has to finish at the level of the unheated rooms and doorways, which can mean digging down or choosing a thin liquid screed. Our page on liquid screed for Farnborough covers the pumped option, and the sand and cement page covers the hand-laid one.

Acoustic heated floors for Farnborough town centre flats

The town centre redevelopment planned by Rushmoor Borough Council includes new homes, and the flats there will need screeds that meet sound insulation requirements between dwellings. Where those floors are also heated, the build-up typically combines an acoustic layer, insulation, the heating pipes and a floating screed, and each layer has to suit the others. Only 5% of Farnborough's homes were built since 2015, so this kind of floor is still a small part of the housing, but it is set to grow.

Whatever the building, commissioning follows the same rules. Your installer pressure tests the circuits before the pour, and ideally leaves them pressurised while we screed. Then the heating waits: calcium sulphate can take it at around 7 days, sand and cement only after 21 days at the least. First runs are low, and the temperature goes up a little at a time.

Only when a test shows the screed is dry does flooring go down. Whatever goes on top, whether tile, LVT or engineered boards, needs the base to be flat. A floor whose heating was brought up carefully stands a better chance of staying free of cracks. Where the spec names a calcium sulphate grade, anhydrite screed in Farnborough explains what it means. For the layers beneath, see insulation and membranes.

FAQs

Underfloor Heating Screed in Farnborough: your questions

Can underfloor heating go into an existing Farnborough floor without digging it up?

Sometimes, but only if there is enough height. A liquid screed needs at least 25mm above the pipes, so a wet system with screed adds around 45 to 50mm plus insulation. Where that height is not available, the floor usually has to be dug out first. We can check levels on site before you commit to a heating design.

Which screed is better over underfloor heating, liquid or sand and cement?

Both work. Liquid wraps the pipes completely, needs less cover and responds faster, so it is the usual choice for homes. Sand and cement needs roughly 45mm of cover and 21 days or more before the heating goes on, but it is the one for wet areas and small rooms. For 2026 the published figure for heated-floor liquid screed is £20 to £35 per m².

Why must the heating be turned up slowly after screeding?

A screed that heats too fast can crack or curl as moisture leaves it unevenly. Start the heating low and raise it gradually over several days, as set out by the screed maker. For calcium sulphate that can begin from about 7 days after pouring; for sand and cement, after at least 21 days.
