Sand and Cement Screeding in Newport Pagnell

For Newport Pagnell floors that need a traditional screed, our team mixes sand and cement at the house and lays it by hand, compacting it firm and level. Much of the town centre is old: 12% of homes here were built before 1919, much of that housing in the historic core, and older properties around the High Street can have solid floors laid straight onto earth. Relaying those floors properly, with a membrane and insulation beneath the new screed, is traditional sand and cement work.

Relaying earth floors around Newport Pagnell High Street

In the older houses around the High Street, a solid floor that sits directly on the ground has neither a damp proof membrane nor insulation beneath it. It may feel cold, show damp patches or crack as the ground beneath it moves. Covering it with new flooring rarely lasts, because moisture keeps rising and the surface keeps breaking up.

The lasting fix is to dig the old floor out to a set depth, lay a membrane and rigid insulation, then finish with a floating sand and cement screed. For a house, we lay it at around 65mm, compact it by hand and power float it until it is dense and level. Our floor preparation service covers breaking out and clearing the old floor when that is needed first. Check the depth before digging: it has to make room for the membrane, the insulation and 65mm of screed below the existing threshold.

Sand and cement copes with the awkward parts of an old house: small rooms, narrow doorways and floor levels that change from room to room, since a hand-laid screed can be built to each level in turn. It also works in the kitchens and bathrooms of older houses, where calcium sulphate screed cannot be used in wet areas.

In a listed building or a conservation setting, check with the council before changing floors, since what is permitted may affect the build-up. Adding fibres to the mix helps resist cracking and costs £1 to £3 more for each m².

Small rooms, garages and falls in Newport Pagnell

Not every sand and cement job is in an old house. In newer Newport Pagnell homes, a converted garage, a downstairs shower room or a small utility is often easier to screed by hand than to set up a pump for. A garage slab usually sits low and slopes towards the door, and sand and cement can be laid thicker at one end to bring it level with the hall. Our guide shows how a converted garage floor is built up.

Wet rooms need a floor that falls gently to a drain. That shape is formed by hand, and it needs a cement based screed that tolerates water.

If the slab underneath is in good order, bonding 25 to 40mm of screed directly to the cleaned concrete saves floor height. Floating screeds over insulation are thicker, at 65mm in homes and 75mm on commercial floors.

The cost is drying time. Up to 40mm deep, reckon on a day of drying per millimetre; beyond that each millimetre takes longer. How depth affects drying is set out in our guide to screed depths.

FAQs

Sand and Cement Screed in Newport Pagnell: your questions

How thick should a sand and cement screed be?

In a house, a floating screed over insulation is about 65mm, rising to 75mm where the floor is commercial. Bonded directly to a sound concrete slab it can be 25 to 40mm, and over underfloor heating pipes it needs roughly 45mm of cover. In an older Newport Pagnell house, the depth available after digging out often decides which build-up we use.

Can sand and cement screed go in a wet room?

Yes, and for a wet room it is normally what we would pick. Cement based screed copes with water where calcium sulphate cannot, and laying it by hand lets us shape the slope down to the drain. The tanking goes on top of the screed once it is dry, before the tiles.

Why does an old solid floor need digging out rather than overlaying?

A floor laid on earth has no membrane to stop damp rising and no insulation, and it may be cracked or sunk. Laying a new screed on top traps the moisture and raises the floor height against doors and skirting. Digging out allows a membrane, insulation and a proper screed at the right level.
