Before your Llanelli delivery arrives

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Llanelli 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.
• Give us the full postcode for the drop point; deliveries around SA15 are priced to the exact address.
• In summer Llanelli gets around 16h 40m of daylight, but early deliveries still beat the traffic and give the longest working day.

Picking the right product

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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Common questions from Llanelli

How soon can damp proofing be delivered in Llanelli?

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.

Where does the DPC go?

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

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.
