Working out quantities for your Islington job
An extension in Islington with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Things to check before you order
DPC width
Match the DPC width to the wall leaf so it runs the full width of the masonry.
Is radon protection needed?
Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; building control will tell you what applies.
In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
Planning the drop in Islington
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Islington is inside our standard mainland delivery area.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
