A quick quantity check

An extension in Wiltshire with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivery to Wiltshire: what helps

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Wiltshire.

• Give us the full postcode for the drop point; deliveries around SN are priced to the exact address.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Damp Proofing & Membranes: choosing well

DPC width

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

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.

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.

Your questions answered

How soon can damp proofing be delivered in Wiltshire?

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.

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.

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

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.
