Things to check before you order
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.
Laps and joints
DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.
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.
A quick quantity check
An extension in Welling with 36 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
How delivery works in Welling
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Welling is inside our standard mainland delivery area.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- With roughly 7h 50m of daylight in Welling around the shortest day, morning deliveries leave more working light for the job.
- If neighbours share the access, it helps to let them know a lorry is coming.
