Sand and Cement Screeding in Bromley

Our sand and cement floors in Bromley are batched at the house, then tamped and trowelled by hand until dense and level. This is the screed for renovation work, cramped rooms, showers and anywhere that has to be cement based. What drives it here is age. Some 17% of the borough's homes predate 1919, and when the solid floor of a Victorian terrace in Penge or Anerley gives up, it may need digging out and relaying over a fresh damp proof membrane.

Rebuilding old solid floors in Penge and Anerley terraces

When an old solid floor in a Victorian terrace fails, patching it rarely makes sense. Normally we break the old slab up, excavate deep enough to fit insulation, put a new damp proof membrane down and screed over the lot. Penge and Anerley have terraces of exactly this age, and those houses can need a new membrane below any fresh screed.

For a rebuild like that, hand-mixed sand and cement is the obvious choice. It is mixed on site in small batches, so it copes with narrow halls, stepped rooms and doorways that a pump hose would struggle through. It can be laid bonded to a sound concrete base, unbonded over a membrane, or floating over insulation. A floating domestic floor is 65mm deep, and 75mm in commercial buildings. Where the existing slab is still sound and the doors leave little room, a screed bonded straight to the slab needs only 25 to 40mm.

We then compact it and power float the surface until it is dense. Expect a slower dry than a pumped floor: about a day for each mm up to 40mm, then longer per mm, so a 65mm floor in a Penge terrace is weeks away from taking moisture sensitive flooring. A hygrometer reading is taken before we hand the room back to you.

Terraced houses make up 21% of Bromley's homes, and room by room work in them is where hand laying earns its keep.

Wet rooms, garages and falls in Bromley houses

Some floors should be cement based whatever else is used in the house. Showers and wet rooms come first, since persistent damp weakens calcium sulphate screed. A hand-laid floor can be shaped to slope towards the drain, and the tiler gets a cement base to fix to.

Converting a garage is the second. A garage slab usually sits a step down from the hall, and closing that gap takes insulation, then a membrane, then screed. See our garage conversion screeding guide for each layer.

It also handles floors that must take weight early or stand up to wear, and the mix can be adjusted. Fibres add £1 to £3 per m² and reduce the risk of cracking in thinner or larger bays, and a fast drying mix, at £20 to £28 per m², helps where the programme cannot wait; see quick drying screed.

If your old Bromley floor is solid but out of level, a fresh screed may be unnecessary. The floor levelling service in Bromley explains when compound alone will do.

FAQs

Sand and Cement Screed in Bromley: your questions

How long before I can tile a sand and cement screed in Bromley?

Count about a day per mm up to 40mm, with each mm beyond that taking longer, so a 65mm floating floor in an extension to a post war Orpington house needs several weeks. Tiles still need the floor to reach the moisture level the adhesive maker sets. A hygrometer reading tells you when it is ready, not the calendar, and good ventilation helps.

Is sand and cement screed as strong as concrete?

It does a different job. Screed is a levelling layer over a slab or insulation, not a structural element, so it is not designed to carry a building's loads. Where a floor will take hard use, ask for a stronger cement screed mix. We do not pour structural power floated slabs, so a Bromley outbuilding needing a new structural base will need a groundworker first.

Do I need a new damp proof membrane under new screed in an old Bromley house?

Yes, whenever the old floor comes out. A new membrane goes in below the insulation or screed and is taken up the walls to link with the damp course. The Victorian terraces of Penge and Anerley are the clearest case in the borough. If the slab underneath is dry and solid, bonding a thinner screed directly to it is sometimes possible instead.
