Planning the drop in Bangor (Down)

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If neighbours share the access, it helps to let them know a lorry is coming.

Sizing your order

An extension in Bangor (Down) with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

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.

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Ordering damp proofing for Bangor (Down): FAQs

Is there a minimum order for delivery to Bangor (Down)?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Can you deliver damp proofing to a site with restricted access in Bangor (Down)?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.

Usually at least 150 mm above outside ground level, linked to the floor DPM.
