Sand and Cement Screeding in Wellingborough

In Wellingborough our team mixes sand and cement on site, lays it by hand and compacts it into a dense, level base that will take any floor covering. It is the natural fit for the older terraces nearer the town centre, where worn solid floors often have to be taken up and relaid over a damp proof membrane. Homes built before 1919 make up 14% of the town's housing, and older rooms with chimney breasts and alcoves are where hand laying works well.

Relaying solid floors in Wellingborough's older terraces

An old solid floor that has lost its damp protection shows it in the usual ways: lifting tiles, a cold and dusty surface, or a musty smell under the carpet. Patching rarely lasts. What lasts is starting again. We break the old floor out, put down hardcore and blinding where needed, then insulation, a damp proof membrane, and finally the new screed.

Sand and cement is the natural material for this. Because we mix it on site for each room, it works around the alcoves, chimney breasts and narrow doorways of an old terrace, and we can do one room at a time while you carry on living in the others. Where it floats on insulation in a house, we lay it about 65mm deep. Keep a sound concrete slab and simply top it, and a bonded layer 25 to 40mm thick may do instead. The screed thickness guide sets out how those depths are decided.

Before any screed goes down, the base has to be right. Old adhesive, loose concrete and contamination all need removing, which our floor preparation service covers.

It is also a slower screed to dry than a pumped one. Give it about a day for every millimetre up to a depth of 40mm, with anything deeper drying more slowly, so a 65mm floor usually needs several weeks before it will pass a moisture test. Where the build cannot wait, we can add a rapid drying admixture to cut that time down.

Garages and wet rooms across Wellingborough

Garage conversions are a regular project on the Hemmingwell, Kingsway and Queensway estates. Inside, the old garage slab is normally a good step down from the rest of the house, so we raise it with layers of insulation, membrane and screed until it meets the hall or kitchen level. Sand and cement suits these small rectangular rooms, and it gives a cement base that carries early load. Each layer is set out in the garage floor screed guide.

The other room where we would reach for sand and cement is a wet room. We can slope it towards a floor drain, and unlike calcium sulphate it is happy in wet areas. The falls are shaped by hand so water finds the outlet, leaving a base the tiler can tank and then tile.

Where speed matters more than cost, the mix can be changed. Quick drying sand and cement shortens the wait before flooring, and fibres can be added for extra resistance to cracking at a small extra cost per m². For a large open extension rather than a small room, compare this page with pumped liquid screed in Wellingborough, which is thinner and faster to lay.

FAQs

Sand and Cement Screed in Wellingborough: your questions

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

On insulation in a house, a floating layer of about 65mm is normal; commercial buildings take about 75mm. Underfloor heating pipes need roughly 45mm of it on top of them. Bonded straight to a sound concrete slab, 25 to 40mm can be enough. We confirm the depth after measuring the finished floor height.

How long before I can tile over a new sand and cement floor?

Count on roughly one day for every millimetre of the first 40mm, with each millimetre after that taking longer. A 65mm floor therefore needs a number of weeks, depending on ventilation and weather. Tiles and other coverings should wait for a hygrometer reading to the limit your flooring maker sets for a cement screed.

Is sand and cement screed as strong as concrete?

It does a different job. The concrete is the structural slab; the screed is the flat layer laid over it to carry whatever floor finish you choose. A properly compacted domestic sand and cement screed is strong enough for homes, and a higher strength mix is used where floors carry heavier loads or traffic.
