How delivery works in Castleford

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Sizing your order

An extension in Castleford with 32 m of cavity wall needs DPC in both leaves: about 3 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.

Things to check before you order

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 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.
