Working out quantities for your Dorset job

An extension in Dorset with 16 m of cavity wall needs DPC in both leaves: about 2 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.

How delivery works in Dorset

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Dorset.

• Give us the full postcode for the drop point; deliveries around BH are priced to the exact address.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Damp Proofing & Membranes: choosing well

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.

Ordering damp proofing for Dorset: FAQs

Is there a minimum order for delivery to Dorset?

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 deliver damp proofing to trades and homeowners in Dorset?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

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.
