Liquid Screed in Croydon

Pumped liquid screed is what we lay in Croydon for apartment floors, open-plan ground floors and new extensions. Once the hose has filled the room, the mix finds its own level, and a day or two later, 24 to 48 hours in most cases, people can walk across it. Croydon has a lot of flats: purpose-built blocks hold 29% of its homes, and those wide, repeated floor plates are where a pumped screed saves the most time on site.

Where pumped screed fits Croydon's flats and extensions

Liquid screed is at its most useful when the floor is big, open or repeated. A pump covers a large area in a day, the screed levels itself without hand compaction, and SR1 or SR2 surface regularity is readily achievable. That flatness matters under LVT and large format tiles.

Croydon has plenty of floors that fit. The town centre has seen tall residential blocks such as Saffron Square, Altitude 25 and IYLO. Newer homes are a real presence too, with 10% of the borough's housing built since 2015. A floor in a new block is one open area over insulation, which is what a pump handles well. Among houses, the semis of New Addington need extension slabs, and a broad extension floor is well suited to a pumped pour.

Depth is thinner than with sand and cement. A domestic floating floor starts from about 35mm and a commercial one from about 40mm, where a traditional screed needs 65mm and 75mm. Heated floors take a minimum of 25mm on top of the pipes, so roughly 45 to 50mm all in, and because the mix surrounds each pipe, nothing is left hollow underneath.

The pumped material comes with one of two bases, calcium sulphate or cement. Both pump and level in much the same way; which one suits depends on the finish, whether the area could get wet and how soon flooring is needed. For the calcium sulphate grades in detail, see the Croydon anhydrite flow screed page.

Pump access on Croydon streets and upper floors

The pump and mixer park as close as possible to the building, and the hose carries the screed inside. On a terraced street in Thornton Heath or Selhurst, that means knowing whether there is a parking space near the door and whether the hose can run through the hall. Where a busy road or controlled parking is involved, tell us when you ask for a price.

For a flat several storeys up, the hose climbs the stairwell or goes in at a window. That makes liquid screed practical for a top floor flat where carrying sand and cement would take all day. We check the route and the floor's acoustic layer beforehand.

For a day or two after pouring, leave windows and doors shut, or a draught can dry the top too fast and form a skin. Walking on it follows in 24 to 48 hours; flooring waits until a hygrometer test shows the screed is dry. Our drying time guide gives the timings by depth.

Pumping is also offered as a service in its own right for builders; see screed pumping. We do not hire out pumps or machines, so every pour is run by our own team.

FAQs

Liquid Screed in Croydon: your questions

How long before I can walk on liquid screed?

Walk on it gently after a day or two; 24 hours is often enough, 48 at the outside. Light foot traffic is fine by then, but the screed is still wet inside and needs weeks to dry for most floor coverings, depending on depth and ventilation. In a Croydon flat kept closed up through winter, drying can be slower, so plan the flooring date around a moisture test.

Can liquid screed be laid over an existing concrete floor in Croydon?

Yes, usually over a separating membrane or floating over insulation. The existing slab needs to be sound, because liquid screed follows every low spot and its depth changes with it. In older Croydon houses we check for damp and failed patches first, then decide whether the slab stays or comes out.

What does liquid screed cost per m² in Croydon?

The 2026 UK rates on record are £24 to £31 per m² for a plain pour and £20 to £35 per m² over underfloor heating. Your own Croydon figure moves with floor size, depth, how close the pump can park and whether we supply the insulation and membrane too. Large, open floors come in lower per m² than a single small room.
