Before your Dumfries delivery arrives

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• In summer Dumfries gets around 17h 23m of daylight, but early deliveries still beat the traffic and give the longest working day.

Getting the right damp proofing

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 Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Working out quantities for your Dumfries job

An extension in Dumfries with 12 m of cavity wall needs DPC in both leaves: about 1 roll in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Your questions answered

Where does the DPC go?

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

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.

Is there a minimum order for delivery to Dumfries?

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 deliver damp proofing to trades and homeowners in Dumfries?

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