Pumped screed for SG1 and Great Ashby new homes
The town centre is being rebuilt through a £1 billion, 20 year regeneration programme, including the SG1 scheme led by Mace and the redevelopment of Queensway North. New homes in the SG1 scheme fall into the category built around pumped liquid screed. On any upper floor, a pump hose runs up to the room, and a whole flat can be poured in one visit with no sand and cement carried up the stairs.
Flats already make up 21% of the town's homes, so upper floors are a common setting for a pumped screed here. The pump and lorry stay at street level while the hose does the climbing, which keeps heavy materials out of shared stairwells and lifts.
Great Ashby is the other half of the picture. Its newer houses call for underfloor heating screeds, and a flowing screed fills around the pipes and settles flat. Liquid screed readily reaches SR1 or SR2 flatness under a 2m straightedge, and a floating domestic screed starts from about 35mm, well below the 65mm of a traditional one. It shrinks little, so large open rooms need fewer joints.
Two binders are on offer for a pumped floor: calcium sulphate, or cement. If an SG1 drawing says CA followed by numbers, that is an anhydrite floor, and our Stevenage page on anhydrite grades covers the sanding and testing it brings. Still undecided? Our pumped versus hand-laid comparison puts cost, speed and depth side by side.
Getting a screed pump to a Stevenage terrace
Not every liquid pour is on a new build. Extensions and garage conversions on the town's 1950s and 1960s terraces need a new insulated slab and a screed that finishes level with the existing floor, and a pumped screed suits that well when the room is large and open.
The practical question is getting the pump close enough. Our pump parks on the road or drive, and its hose snakes through the front door, down the hall and into the extension. If the house fronts a footpath, or parking is some way off, mention it when you ask for a price so the route can be worked out. What that machinery looks like is shown under pumping services.
Ahead of us arriving, perimeter strip should line each wall, the polythene over the insulation should have its seams taped, and every doorway wants a stop to hold the flow back. After it, allow time to dry. Within a day or two you can cross it on foot; carpet fitters and tilers, though, wait for a moisture reading. Roughly one day per millimetre for the first 40mm, then slower, is the working rule; the drying time guide goes further.
