How delivery works in Merthyr Tydfil

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Merthyr Tydfil 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.
• In summer Merthyr Tydfil gets around 16h 41m of daylight, but early deliveries still beat the traffic and give the longest working day.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Sizing your order

An extension in Merthyr Tydfil with 28 m of cavity wall needs DPC in both leaves: about 3 rolls 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.

Things to check before you order

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.
