Planning the drop in Lisburn

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• On busy streets in Lisburn, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• With roughly 7h 16m of daylight in Lisburn around the shortest day, morning deliveries leave more working light for the job.

Sizing your order

An extension in Lisburn with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Damp Proofing & Membranes: choosing well

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.
