Extensions and knock-throughs in Great Baddow and Springfield
Semi-detached houses make up 32% of Chelmsford's homes, and on a typical post-war semi the rear extension and the old kitchen become one room. That creates a single wide floor in which the new screed must finish flush with the original floor at the old back wall.
Liquid screed handles that well. We set the level, the screed runs out to meet it unaided, and SR1 or SR2 surface regularity follows without a struggle. It also shrinks little, which means far fewer joints across a big open floor than sand and cement would need.
How deep it goes is decided by the layers below. Floated on insulation in a Great Baddow semi it needs about 35mm as a minimum, and closer to 40mm in a commercial building. Heating pipes want 25mm or more of screed sitting over them. When the level of the old floor is fixed, those depths decide how much insulation fits below, so it is worth measuring early, ideally before the extension's foundations and slab are poured.
Two kinds of pumped screed exist, one bound with calcium sulphate and one with cement. Either can suit an extension, and the room's use and floor finish decide between them. Flats are another case: the city's large flat stock brings acoustic work, and a flowing screed can be laid as a floating floor over an acoustic layer. For a fuller comparison, read liquid screed or sand and cement.
Pump access and drying in Chelmsford
We have to get the lorry and pump near enough for the hose to reach the room. If your semi has its own drive, the run is short and easy. On an older terrace near the centre, the pump may have to sit on the street, so mention parking controls and side access when you ask for a price. Flats above ground level are reachable by running the hose up the communal stairs or in at a window, with the managing agent's say-so.
Foot traffic can usually go on after 24 to 48 hours. Coverings must wait longer, with each of the first 40 millimetres taking roughly a day and anything deeper drying at a slower rate. Leave the room shut up for roughly two days, then get plenty of air through it. A moisture test confirms when tiles or LVT can go down.
Plans showing a calcium sulphate grade are dealt with on the Chelmsford anhydrite page. For the same service a short way east, see liquid screed in Maldon, or for longer hose runs, our screed pumping service.
