Dartington builders sometimes need a screed that can be laid in a bucket-and-barrow operation with no pump access, or that has to tie into an external step, drain or wet room upstand. That is exactly where sand and cement wins over a liquid pour.
Sand and cement screed is laid in bays with day joints, which we set out to avoid future cracking at natural stress points such as doorways and changes in depth. It is a more labour-intensive process than liquid screed, but it is proven, robust and unaffected by moisture the way calcium sulphate screeds can be.
Most of our Dartington jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Dartington sits Exeter (25 mi), and we work the surrounding villages on the same week's diary.

Traditional Sand & Cement Screed in Dartington — how it works
For Dartington wet rooms, balconies and any area with sustained water contact, sand and cement is usually the only sensible screed choice, since gypsum-based liquid screeds are not designed to tolerate standing water.
We mix a semi-dry sand and cement screed on site or bring it in via a screed pump, lay it to string lines or laser-set pins in bays, then compact and trowel it to a flat, dense surface. It is slower than a liquid pour, roughly a day of drying time per millimetre of depth once you get past the first 50mm, but it tolerates a much wider range of site conditions.
Built for Dartington rural self-builders and farms
Dartington sits rural — barn conversions, self-builds, agricultural sheds, equestrian floors. Access is usually fine, but power and water on site need confirming up front. We do that at the site visit.

Common Dartington build questions
Can sand and cement screed go over underfloor heating?+
It can, though thermal response is slower than a liquid screed because of the voids that form around hand-laid pipework. For Dartington UFH jobs we will usually recommend liquid screed unless there is a specific reason to use sand and cement.
How is sand and cement screed different from liquid screed in Dartington?+
Sand and cement is a semi-dry mix, hand-laid and trowelled in bays, whereas liquid screed is pumped and self-levels. Sand and cement suits deep fills, external areas and wet rooms; liquid screed suits large flat internal floors that need to dry quickly.
Will the screed crack?+
Bay joints and fibre reinforcement control shrinkage cracking. We set bay sizes and joint positions at doorways and depth changes to minimise the risk on any Dartington job.
What SR rating do you achieve on a trowelled screed?+
We finish sand and cement to SR2, within 3mm under a 2m straight edge, which is suitable for most tiled finishes. If you need SR1 flatness for large-format tile or resin, liquid screed is usually the better route.
How long does a sand and cement screed take to dry in Dartington?+
Roughly a day per millimetre of depth once past the first 50mm, so a 65mm floor is typically ready for coverings in around six to eight weeks, depending on ventilation and site conditions.
Can you match an existing sand and cement floor level?+
Yes, we set datums off your existing finished floor level and build the new screed to match, allowing for whatever covering goes on top.
