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.

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.

Delivery to Irvinestown: what helps

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.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
