The floors going in in Cork
Scheme houses were 72% of the 3,715 new homes finished in Co. Cork in 2025: the same floor, house after house. That's where a pumped liquid screed saves days on the programme. Another 3,292 homes were finished from January to September 2026. Cork is 2nd of the 26 counties for new homes and 1st for one-off houses.
Newer houses and heating in Cork
32% of homes in Co. Cork were built from 2001 on, and 27% had a renewable energy source such as a heat pump or solar panels at the 2022 census, against 8% built since 2011 nationally. New and extended houses here are where underfloor heating goes in, and where a liquid screed pays its way.
A calcium sulphate screed conducts heat about twice as well as sand and cement, and it wraps the pipe with no air round it. Over the pipes it goes down 25 to 30 mm, so the floor warms up faster and the heat pump runs at a lower temperature.
Winter and drying in Cork
Cork has about 1,755 heating degree days a year, our calculation from Met Éireann's 1991 to 2020 averages: a milder heating season than the middle of the 26 counties (25th coldest).
Liquid screed dries about 1 mm a day for the first 40 mm in good conditions, then 2 days per mm. In a cold, damp building it's slower. Keep the building closed for the first 48 to 72 hours, then warm and ventilated. With underfloor heating, a calcium sulphate screed can be force-dried from day 7.
Radon under the screed in Cork
13% of the 6,469 homes the EPA has measured in Co. Cork were at or above the radon reference level of 200 Bq/m³ (11th of 26 counties; 14% nationally). In a High Radon Area the membrane goes under the insulation, so a floating liquid screed sits on top of it. The polythene under the screed is lapped and taped so the screed can't run through, and the edge strip is fixed before the pour, never through the membrane.
What liquid screed costs in Cork
Liquid screed in Co. Cork is priced per m² for your floor. What moves it: the area, the depth, calcium sulphate or cement-based, how close the truck can get, and whether the price includes sanding and priming. A 60 m² extension at 50 mm is 3 m³ of screed; the same floor at 40 mm is 2.4 m³.
29% of people in Cork live outside any town. On a rural site, tell the contractor about the lane and the turning space: the truck and the pump need to get within reach of the house. See liquid screed cost.
