Delivering damp proofing in Dungannon

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 the site is up a shared drive or behind other houses, tell us the distance from the road.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

Working out quantities for your Dungannon job

An extension in Dungannon with 28 m of cavity wall needs DPC in both leaves: about 3 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.

Getting the right 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.

Laps and joints

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

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.
