Before you order damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

Before your Magherafelt 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.

• If neighbours share the access, it helps to let them know a lorry is coming.
• With roughly 7h 13m of daylight in Magherafelt around the shortest day, morning deliveries leave more working light for the job.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Quantities: a worked example

An extension in Magherafelt with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
