Picking the right product

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 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.

Estimating your damp proofing

An extension in Downpatrick 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.

Before your Downpatrick delivery arrives

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.

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• On busy streets in Downpatrick, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
