Quantities: a worked example

An extension in Portishead with 12 m of cavity wall needs DPC in both leaves: about 1 roll in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

How delivery works in Portishead

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

• With roughly 7h 50m of daylight in Portishead around the shortest day, morning deliveries leave more working light for the job.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Choosing damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

Questions about damp proofing delivery in Portishead

How soon can damp proofing be delivered in Portishead?

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.

Do you supply cavity trays?

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

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.

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.
