For Alphington jobs where gypsum-based screed is ruled out, wet rooms, balconies, timber-sensitive junctions, we lay a semi-dry sand and cement mix, bay by bay, finished to SR2 with a hand float or power trowel.
For Alphington 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.
Most of our Alphington jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Alphington sits Exeter (1 mi), and we work the surrounding villages on the same week's diary.

Traditional Sand & Cement Screed in Alphington — how it works
For Alphington 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.

Semi-dry, hand-compacted mix ratio adjusted to depth and loading.
SBR bonding agent
Slurry-brushed onto the substrate for bonded screeds under 40mm.
Polypropylene fibre reinforcement
Added to reduce shrinkage cracking on larger bays.
DPM and separating membrane
For unbonded or floating screeds over insulation.
Falls formed to drain outlets
Built into the screed thickness for wet rooms and balconies.
Edge and movement joints
Set at bay lines, doorways and around columns.
Step-by-step for a Alphington job
- 1
Site visit to assess substrate, falls, depth and access, since sand and cement can be barrowed where a pump truck cannot reach
- 2
Substrate prep, priming or DPM, and setting out of bay lines and laser levels
- 3
Mix and place the screed in bays, compacting as we go to remove voids
- 4
Hand float or power trowel to a flat, dense SR2 finish
- 5
Protect and allow to cure, typically a day per millimetre of depth after the first 50mm
- 6
Follow-up inspection before floor coverings or tiling begin

Common Alphington 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 Alphington UFH jobs we will usually recommend liquid screed unless there is a specific reason to use sand and cement.
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 Alphington job.
How is sand and cement screed different from liquid screed in Alphington?+
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.
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.
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.
Do you use a screed pump for sand and cement in Alphington?+
On larger jobs, yes, a screed pump can deliver the semi-dry mix into the building, which speeds up placement while keeping the hand-trowelled finish.
EX2 coverage for traditional screed
From Alphington out to the surrounding villages, we carry both liquid and sand and cement screed crews, so you get the right one for the job.
