Where pumped screed suits Borehamwood flats and extensions
Liquid screed is at its most useful where floors are large, open or hard to reach. In Borehamwood that means three kinds of job.
The first is flats. Post-war blocks and newer apartment schemes both need floors replaced from time to time, and the screed usually has to sit on an acoustic layer. A flowing screed settles to an even thickness over that layer without being trodden and compacted, which matters when the build-up beneath it is soft.
The second is the rear extension on a post-war terrace or semi, where the kitchen is knocked through into one open room. Pumped in, the screed spreads over the entire knocked-through room in a single pour, reaches SR1 or SR2 without much trouble, and shrinks so little that it needs far fewer joints than a floor laid by hand.
The third is new building. In Borehamwood 20% of homes were built since 2000, and on new build sites liquid screed over underfloor heating is a common specification.
Depth is the other reason people choose it. Over insulation in a Borehamwood semi, a flowing screed can be as thin as about 35mm, while a floating sand and cement floor wants about 65mm, and that saving often decides whether the extension floor meets the old kitchen doorway flush. The pumped material comes in two kinds, one with a calcium sulphate binder and one with cement. The Borehamwood anhydrite flow screed page deals with specifying them, and our guide to liquid versus sand and cement screed weighs one against the other.
Getting the hose into a Borehamwood flat or terrace
The mixing and pumping kit stays outside on the drive or the street, with a hose carrying the screed indoors. For a ground floor extension on a semi with a driveway, the route is short. Borehamwood's terraced streets are harder: with no drive, the pump often ends up parked in the road, so mention yellow lines, permit bays or a narrow shared passage before we price the job.
Upper floors are where pumping earns its keep. The hose can run up a communal staircase, but the building manager usually needs to agree the route, and stairs, lifts and door frames must be protected along the way. That permission should be in place before a pour date is fixed.
By the time we arrive, edge strip should be fixed round every wall, each membrane joint taped and every doorway dammed so the screed stays in the room. Once it is down, leave it undisturbed and follow the drying advice for the product used.
Foot traffic is fine once 24 to 48 hours have passed, yet that is no guide to when the flooring fitter can start. Each millimetre up to 40mm costs near enough a day of drying, and each one after that costs more, so a deep heated floor in a new Borehamwood extension stays off limits to the flooring fitter for weeks. When booking the flooring fitter, use our guide to screed drying times to pick a realistic date.
