Delivery to Hatfield: what helps

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

• In summer Hatfield gets around 16h 41m of daylight, but early deliveries still beat the traffic and give the longest working day.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Things to check before you order

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.

DPC width

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

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.

How much will you need?

An extension in Hatfield with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Questions about damp proofing delivery in Hatfield

Where does the DPC go?

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

Can you deliver damp proofing to a site with restricted access in Hatfield?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.

How soon can damp proofing be delivered in Hatfield?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
