Delivering damp proofing in Shirley

• In summer Shirley gets around 16h 49m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Picking the right product

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 Shirley with 32 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.

Damp Proofing & Membranes in Shirley: questions

Where does the DPC go?

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

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.

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

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

Is there a minimum order for delivery to Shirley?

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.
