Sand and Cement Screed in Hemel Hempstead

In Hemel Hempstead K & B mixes sand and cement on site the old-fashioned way, then lays and compacts it by hand into a dense, level floor. The terraces and semis of the planned neighbourhoods are now around 70 years old, and their floors often need patch repairs to breaking up screed or a full dig out and relay. Sand and cement is the practical material for those small, awkward and wet rooms.

Relaying tired floors in Chaulden and Bennetts End

Only 5% of homes were built before 1919 and 6% between the wars, so the typical old floor here is a post-war new town floor rather than a Victorian one. Those floors, in Chaulden, Bennetts End, Adeyfield and the other early neighbourhoods, have had around 70 years of use, and the screed on top of the slab can crack, go hollow or break up at the edges.

A small area can sometimes be cut out and patched, which is covered on our screed repairs page. When the damage is spread across the room, or the owner wants insulation under a new floor, the old floor is dug out and rebuilt: a membrane, insulation boards, an edge strip, then a floating sand and cement screed at 65mm for a house.

There are good practical reasons to do these floors by hand. Small batches mean the hallway, the cloakroom and the kitchen can each go down at their own depth. It can be bonded straight to a sound slab at 25 to 40mm where headroom is tight, or laid floating over insulation where it is not. It can also be dressed to fall towards a drain, something a flowing screed will not do.

If the floor is sound but simply out of level, it may not need a screed at all, and levelling compound for uneven floors is the cheaper route.

Wet rooms, garages and drying in Hemel Hempstead

Some rooms need a cement floor whatever else is used in the house. A walk-in shower or wet room in one of these houses goes down in sand and cement, sloped to the waste, because calcium sulphate screed is not suited to a floor that may get wet. The same material suits garage conversions, which need a new insulated floor raised to meet the house; our garage floor screed guide walks through the build-up.

Where a floor will take early load, such as a utility room with heavy appliances, fibres can be added for crack resistance; see fibre reinforced screed for when that is worth the extra £1 to £3 per m².

The trade-off is drying. At about one day for each millimetre through the first 40mm, then slower, a 65mm Hemel floor needs a matter of weeks before most finishes can go down. Line up the tiler and the kitchen units for after that point, not before it. Whether the house is in Piccotts End, Two Waters or Frogmore End, the depth sets the timetable, and a quick drying mix can shorten it where the programme is tight.

FAQs

Sand and Cement Screed in Hemel Hempstead: your questions

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

Floating over insulation, a domestic floor is laid at 65mm, and 75mm is used for commercial floors. Bonded to an existing concrete slab in good condition, it can be as thin as 25 to 40mm. With heating pipes inside it, allow roughly 45mm above them. Once we have seen what lies beneath your current floor, we confirm the figure.

Can I lay a sand and cement screed myself?

A small patch, perhaps. A whole room is harder than it looks, because the mix must be compacted evenly across the full depth and ruled flat to a tight tolerance. Poor compaction leaves a weak, hollow layer that breaks up under tiles later, the same fault found in many older floors. A fixed written price costs nothing to request.

Is sand and cement screed as strong as concrete?

No, and nobody expects it to be. The concrete slab is the structure, and the screed is the level layer laid over it to give your floor finish a flat, dense base. Properly compacted, sand and cement stands up well to household wear, and a stronger mix can be used for a floor that will work harder.
