Things to check before you order

Laps and joints

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

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.

Getting damp proofing onto your Worcester site

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• With roughly 7h 42m of daylight in Worcester around the shortest day, morning deliveries leave more working light for the job.

Estimating your damp proofing

An extension in Worcester with 36 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Ordering damp proofing for Worcester: FAQs

Where does the DPC go?

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

Do you deliver damp proofing to trades and homeowners in Worcester?

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.

Is there a minimum order for delivery to Worcester?

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.
