Damp Proofing & Membranes for Cramlington, delivered to site

Choosing from our damp proofing range

• Cavity trays and stop endsTo direct water out of the cavity over openings.

Getting damp proofing onto your Cramlington site

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Estimating your damp proofing

An extension in Cramlington with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes: choosing well

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.

Damp Proofing & Membranes questions

Can I add other materials to my Cramlington 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.

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.

Where does the DPC go?

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

Is there a minimum order for delivery to Cramlington?

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.
