Pumping liquid screed into Lower Sunbury extensions
A wraparound extension on a 1950s semi often joins the kitchen, dining space and an old side return into one floor. Liquid screed is pumped straight from the mixer, finds its own level and is dappled to release air, so a floor of that size is laid in a day with no visible joins across the open plan.
Depth comes first. Floated over insulation with no pipes, domestic floors start at roughly 35mm, and offices or shops at 40mm. Put heating pipes underneath and 25mm must sit over their crowns, giving a 45 to 50mm layer from insulation to surface. That thinner section is useful where the new floor must meet the existing slab at the same height.
Then there is the finish. SR1 and SR2 both come without a fight from a flowing screed, which is what your tiler or LVT fitter will be hoping for, and engineered wood likes it too.
The products come in two families. Calcium sulphate liquid screeds are the common choice for heated domestic floors, and cement based liquid screeds are used where the specification calls for them. The anhydrite flow screed page for Sunbury covers the calcium sulphate material in detail.
Sunbury's post-2000 housing, 15% of the stock, is a natural match as well, as many of those floors were designed for flowing screed at drawing stage. For a side by side comparison of the two main approaches, read liquid screed vs sand and cement.
Getting the hose to Sunbury Common flats and terraces
Pumping is fast, but the mixer and pump still need somewhere to stand. On Sunbury Common's terraced streets the lorry usually parks at the kerb and the hose runs through the house to the back room, protected along the way. We agree the parking and the hall protection before the day.
Flats are a different exercise. Flats make up 26% of the town's homes, and some are in the taller blocks and residential conversions around Sunbury Common. The hose can be taken up a stairwell or lifted to a window, and long runs are planned in advance so the material arrives at the right consistency. Our screed pumping service explains how the line is set up.
Drying follows a simple pattern. Through the first 40mm, think of drying as 24 hours per millimetre, and the deeper part dries slower still. A 50mm floor over heating will need several weeks of good ventilation before a moisture test, unless the heating is used to bring it down once the screed is ready.
