Getting the right 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 England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Working out quantities for your Arnold job

An extension in Arnold with 20 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.

Planning the drop in Arnold

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Arnold is inside our standard mainland delivery area.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• On busy streets in Arnold, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Questions about damp proofing delivery in Arnold

Is there a minimum order for delivery to Arnold?

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.

Where does the DPC go?

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

Do you supply cavity trays?

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

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

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.
