Things to check before you order

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

Quantities: a worked example

An extension in Maidenhead with 36 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.

Getting damp proofing onto your Maidenhead site

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• On busy streets in Maidenhead, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Questions about damp proofing delivery in Maidenhead

Can I add other materials to my Maidenhead 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.

Is there a minimum order for delivery to Maidenhead?

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.

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.

Where does the DPC go?

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