Renovation pours in the South West are always three problems in one — a substrate you didn't build, a build-up that has to fit under existing thresholds, and access that was designed for people not pumps. We plan around all three before we quote.
Retrofit pours in our regional coverage usually go bonded — 30–40mm of Cemfloor on a sound, primed existing slab, ideal where door thresholds and stair heights are fixed. We prime, edge-isolate, pour, spike-roll, cover.
For fresh DPM builds on a core Devon & Somerset renovation we pour 50–65mm unbonded. The heavier build-up gives UFH-friendly thermal storage and a proper barrier against ground moisture in older properties.

For fresh DPM builds on a the South West renovation we pour 50–65mm unbonded. The heavier build-up gives UFH-friendly thermal storage and a proper barrier against ground moisture in older properties.
The trickier bit is always the door thresholds and stair nosings. We laser-check the pour depth against every one before we start, and we won't quote a renovation blind — site visit first, quote second.
