Working out quantities for your Coalisland job

An extension in Coalisland with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivering damp proofing in Coalisland

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.

• With roughly 7h 16m of daylight in Coalisland around the shortest day, morning deliveries leave more working light for the job.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Before you order damp proofing

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.

Common questions from Coalisland

Can I add other materials to my Coalisland delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building control requires radon protection in new buildings and extensions.

How soon can damp proofing be delivered in Coalisland?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.
