Liquid Screed in Bexley

Pumped liquid screed is what the new flats and houses in Bexley's Belvedere and Erith growth areas call for, and it works well in open-plan extensions on the borough's semis too. It goes from the mixer straight down the hose, letting us finish an entire floor in one day, and it takes foot traffic after 24 to 48 hours. Just 10% of Bexley's homes were built in 2000 or later, but that is changing in the north of the borough, where the new homes are rising.

Bexley Riverside and the pumped floor

Northern Bexley sits in the Thames Gateway. Its Bexley Riverside Opportunity Area covers Erith, Crayford, Slade Green and Belvedere, and the new flats and houses going up there are specified with liquid screed over heating pipes, usually with acoustic layers between flats. Peabody is rebuilding parts of Thamesmead too, the 1960s concrete new town that Bexley shares with Greenwich.

Floor plates that repeat level after level are pump work: the hose puts down big volumes far quicker than barrows can. Left to flow, the screed levels itself, so it reaches SR1 or SR2 flatness under a 2m straightedge without fuss. It shrinks so little that a wide area needs only a handful of the joints sand and cement would, and because it wraps every heating pipe without leaving gaps, the floor warms up more quickly.

It is thinner, too. Floating liquid screed starts at about 35mm in houses and flats and about 40mm in commercial buildings, where sand and cement would be 65mm or 75mm. Above heating pipes it must have 25mm of cover or more.

Two kinds get pumped: one bound with cement, the other with calcium sulphate. The calcium sulphate kind has to be sanded and moisture tested with care, all set out on our anhydrite screed page for Bexley. With 23% of Bexley's homes being flats, it helps that on an upper floor the hose just runs up the stairs to the room, which saves a great deal of carrying.

Open-plan extensions on Bexley semis

New blocks are not the only place for it. Knock a Bexley kitchen through into a rear extension and you get a big open floor, which is just the kind of space a self-levelling screed suits. It is set to meet the existing floor at a fixed height, stays flat from wall to wall and gets by with few joints.

On a Welling or Blackfen semi, the pump and mixer can normally stand out front on the drive or kerbside, with the hose taken down the side passage or along the hallway to the extension at the back. Suburban streets in the borough usually make this easy, but let us know if the only way in is a narrow side passage or across a neighbour's access.

Before we come, edge strip needs fixing round the walls, a membrane laying over the insulation with every joint taped and dams fitting across the doorways. If you want us to supply that build-up, our insulation and membrane service does so.

Plan around the drying. Think in days per millimetre: around one each for the first 40mm, then more, and a test should come before any flooring. The figures are explained in how long screed takes to dry. Just over the Kent border, see Dartford liquid screed.

FAQs

Liquid Screed in Bexley: your questions

How long before I can walk on liquid screed in a Bexley extension?

Give it 24 to 48 hours and it will normally bear people walking over it with care. Ladders, piled materials and anything heavy should stay off for longer. A floor you can walk on is not yet a dry floor, so tiles, LVT and timber wait until a moisture reading shows the screed is ready for whichever finish you have chosen.

Is liquid screed dearer than sand and cement in Bexley?

Usually a little, measured per square metre. Per m², liquid costs more: £24 to £31 on the published 2026 UK figures, set against £18 to £25 for sand and cement. Across a bigger open floor in an extension, pumping speed and the shallower depth can narrow that difference. For a very small room, sand and cement laid by hand often ends up cheaper.

Can liquid screed be poured over a suspended timber floor?

Not directly. A liquid screed needs a solid, stable base or a properly built floating floor over insulation. Where an extension joins an older Bexley semi with a suspended timber floor, the new floor is built as its own slab and insulated, and the two are matched at the threshold.
