Open plan kitchens in Potters Bar semis
In a typical project, the back wall of a semi comes down, a new extension goes on, and the kitchen, dining area and extension become one room. The floor in that room now has three parts: the original slab, any old screed on top of it, and a new extension base. Liquid screed ties them together.
The trick is height. Getting insulation and screed to the right depth to match the existing floor is often the main challenge in these houses. Because liquid screed can be floated at around 35mm in a house, a semi has more room left for insulation than a traditional screed allows. Levels are set across the whole room before the pour, and the self-levelling screed finishes to SR1 or SR2 under a 2m straightedge without power floating.
Speed helps too. A large room is poured in one visit, and the builder can walk on it after a day or two, although flooring still has to wait for it to dry. The thinner layer pays off in drying too, at roughly one day per millimetre up to 40mm. Our guide on liquid versus traditional screed compares the two methods.
There are calcium sulphate and cement based versions, and which one goes in depends on what the room is. Where a kitchen extension includes a shower room or utility, the wet area may need a different product. If the extension has heating in the floor, read our page on heated floor screed in Potters Bar as well.
New homes on the High Street and Dugdale Hill
New building is on its way in Potters Bar. Chase New Homes has a 4.5 acre High Street site, once Canada Life offices, for around 260 homes, and the Hertsmere Local Plan names garden suburb sites west of Dugdale Hill and on the former golf course off The Avenue. Flats and houses on schemes like these commonly use liquid screed over underfloor heating.
For a site manager, the advantages are area and programme. A pump can cover large floors in a day, fewer joints are needed than with sand and cement, and trades can walk on the floor soon after. On an apartment block, the hose runs from the pump to each floor, so we plan the route and the order of pours with the site team. Specified CA grades are covered on the calcium sulphate flow screed page.
For single homes, access is the main question. Tell us where the lorry could pull up and roughly how many metres of hose it would take to reach the room. For projects just outside town, see our liquid screed in Hatfield page.
