Dedworth extensions and open-plan liquid screed floors
A Dedworth semi extended at the back often ends up with one long room: the old kitchen, the new extension and sometimes a dining room, all opened into each other. The new floor has to cover all of it at one level and meet the hall at the door.
A single pour covers all of it. It spreads under its own weight across the whole area and is worked flat with a dappling bar, so the old and new parts of the room finish in the same plane. Across that long room it can reach SR1 or SR2, which leaves a 2m straightedge with a gap no bigger than 3mm or 5mm.
The depth is modest. Floating on the insulation of a Windsor house, liquid can go as thin as about 35mm; sand and cement there needs 65mm. That difference can go into thicker insulation or save digging out the old kitchen floor. Because it shrinks so little, even a big room gets by with only a few joints.
You can have a calcium sulphate liquid screed or a cement based one, and the pump and pour are the same for both. Where the floor might get wet, the cement based type is the safer choice. If the extension is to be heated, a liquid screed flows fully around the pipes with no voids; our page on heated floor screeds in Windsor explains depths and heat-up. The two methods are set side by side in our guide comparing the two screeds.
The pump and its operator are part of our service. Pumps and machines are not available for hire from us.
Pumping liquid screed into Windsor flats
Purpose-built blocks hold 24% of Windsor's homes, and a pumped screed is a natural fit for flats like these. With the pump parked on the street, the hose is run up a stairwell or in through an upstairs window, so a whole flat is done in a single visit.
On a terraced street the route is more often through the house. The hose is laid along the hall to the back room, with the floors protected, so plan for a clear path and tell us about any tight turns or steps.
Windsor has comparatively little recent building, with 11% of its homes dating from 2000 onwards. So a liquid screed here usually goes into an existing home rather than a new build, and the hose route and the level of the floors either side need settling before the pour.
People can usually walk on it 24 to 48 hours after the pour, though it will be some weeks before the flooring can go down. Expect around one day of drying for every millimetre up to 40mm, and slower progress beyond that; our guide to screed drying covers what helps it along.
