Sand and Cement Screed in Rochester

In Rochester, sand and cement screed is the usual answer when an old floor is rebuilt, a room is small or wet, or a floor must carry load early. One figure stands out: 19% of Rochester homes predate 1919, and a ground floor of that age may have been laid with no damp proof membrane at all. Preparation and a membrane come first, then insulation and a screed mixed on site, placed and compacted by hand.

Rebuilding floors without a membrane in older Rochester houses

Damp, lifting tiles and a musty smell under a floor covering are the usual signs that an old solid floor has no membrane. Sealing the surface rarely fixes that, because moisture keeps rising from below. What lasts is taking the old floor out completely and building a new one from the base upwards.

That rebuild follows a set order. First we dig out the old floor and make good whatever lies beneath. Next comes the damp proof membrane, overlapped at the joins and taken up the face of each wall. Insulation follows, then a floating sand and cement screed at 65mm, which is the domestic depth. In commercial space the figure is 75mm.

Each batch is mixed on site for that room's size and depth. It is laid in bays, compacted by hand and finished level, ready for tiles, wood or sheet flooring. Because nothing is pumped, it suits small rooms, narrow halls and houses where the street leaves no room for a truck.

If the slab below is still sound but there is little height to spare, we bond a thinner 25 to 40mm layer straight to the prepared concrete. Our bonded screed service covers that method, which published 2026 figures price at £12 to £18 per m² (trade2base, June 2026).

Homes built between the wars make up 18% of the stock, and their floors can need the same assessment. Its drying clock runs slower than a pumped floor's, at around one millimetre a day through the first 40mm.

Wet rooms, garages and early loads in Strood and Borstal

Whether a house is old or new, certain rooms belong on cement. A wet room needs falls running to its gully, and trowelling the screed by hand gets those falls accurate. Calcium sulphate is not for floors that may stay wet, which leaves sand and cement as the sound choice.

Garage conversions are another use, wherever a house in Strood, Borstal or elsewhere has an integral or attached garage. Garage slabs are generally set a step down from the house floor. Building up insulation, a membrane and screed on top lifts it to match and keeps the new room warm. Every layer of that build is set out in screeding a garage for conversion.

Where a floor has to take weight early, such as a workshop or a kitchen with heavy stone worktops going in, cement screed gives a solid base. Adding fibres costs £1 to £3 per m² and helps stop cracks, and a stronger sand and cement mix can go in where the floor will work harder.

In a hurry? An additive that speeds drying brings the flooring date forward. Nearby, we lay sand and cement screed in Gillingham on the same basis.

FAQs

Sand and Cement Screed in Rochester: your questions

How thick should sand and cement screed be in a house?

In a house, a floating layer on insulation is laid at 65mm, and a commercial building gets 75mm. Where heating pipes are involved, the mix must bury them under about 45mm. Bonded directly to sound concrete, the layer can drop to 25 to 40mm. We confirm the depth after measuring the existing floor and the finished level required.

Can I lay sand and cement screed myself?

Someone handy can manage a small patch, but doing a full room well is tough. Every batch needs the same mix, packed down hard and trowelled level wall to wall, and if it is not compacted properly the floor ends up weak and hollow and cracks once tiled. We give a fixed price, so you can compare it with the cost of a failed floor.

Why does an older Rochester floor need a damp proof membrane?

Pre-1919 ground floors were often laid straight onto the ground without one, so moisture can rise through them. Modern floor finishes, adhesives and insulation do not cope with that. A membrane under the new screed stops rising damp and protects the insulation, and it is a normal part of rebuilding an old solid floor.
