Before your Clevedon delivery arrives
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Clevedon is inside our standard mainland delivery area.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
- In summer Clevedon gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
Quantities: a worked example
An extension in Clevedon with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Damp Proofing & Membranes: choosing well
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.
Damp Proofing & Membranes in Clevedon: questions
How thick should a DPM be?
1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.
Do you deliver damp proofing to trades and homeowners in Clevedon?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
Where does the DPC go?
Usually at least 150 mm above outside ground level, linked to the floor DPM.
