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.

Laps and joints

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

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.

Planning the drop in Manchester

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Manchester 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.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Sizing your order

An extension in Manchester with 28 m of cavity wall needs DPC in both leaves: about 3 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.

Damp Proofing & Membranes in Manchester: questions

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 Manchester?

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 supply cavity trays?

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

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

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