Order damp proofing for delivery in Bangor (Gwynedd)
Damp proofing materials stop moisture rising or passing through a building: a damp-proof course (DPC) in the walls and a damp-proof membrane (DPM) under the floor.
Trades and homeowners in Bangor (Gwynedd) can order damp proofing for delivery by sending a list, a drawing or just the sizes of the job.

Delivery to Bangor (Gwynedd): what helps
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Bangor (Gwynedd) 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.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
Before you order damp proofing
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.
DPC width
Match the DPC width to the wall leaf so it runs the full width of the masonry.
Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
Sizing your order
An extension in Bangor (Gwynedd) with 20 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.
Common questions from Bangor (Gwynedd)
Can I add other materials to my Bangor (Gwynedd) delivery?
Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.
Where does the DPC go?
Usually at least 150 mm above outside ground level, linked to the floor DPM.
How soon can damp proofing be delivered in Bangor (Gwynedd)?
We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
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.
