Delivering damp proofing in Chapeltown

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Quantities: a worked example

An extension in Chapeltown with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

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 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 Chapeltown: FAQs

Where does the DPC go?

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

Can I add other materials to my Chapeltown delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.

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

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.

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.
