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.

Quantities: a worked example

An extension in Portadown with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

How delivery works in Portadown

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.

• On busy streets in Portadown, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Questions about damp proofing delivery in Portadown

Can you deliver damp proofing to a site with restricted access in Portadown?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

Is there a minimum order for delivery to Portadown?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

Where does the DPC go?

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