Extensions in the South West — usually 15–40m² kitchen-diner rear pours — are our bread and butter. We turn up, pour, and are out inside a morning, leaving a laser-flat floor ready for cover.
For an extension pour in our regional coverage, prep is usually the builder's — insulation and DPM in, UFH pipes clipped and pressure-tested, edge isolation continuous around the room. We turn up, run the pump line in, pour to the laser, spike-roll, and leave you covered up before the trades leave site.
The mix is Cemfloor at CT-C30-F4 or F6 depending on how quickly the floor covering needs to go on. On smaller core Devon & Somerset extensions we use ready-mix delivery and a small screw pump — enough for 40m² easily.

Extension Floor Screed — how we run it
For an extension pour in the South West, prep is usually the builder's — insulation and DPM in, UFH pipes clipped and pressure-tested, edge isolation continuous around the room. We turn up, run the pump line in, pour to the laser, spike-roll, and leave you covered up before the trades leave site.

The pour is 90 minutes of work, but the day-plan is the whole morning: mobilisation, protection to the rest of the house, pump line in, pour, spike-roll, cover, demob. That's a normal the South West extension shift for us.
