Planning the drop in Chippenham

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

How much will you need?

An extension in Chippenham with 32 m of cavity wall needs DPC in both leaves: about 3 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.

Damp Proofing & Membranes: choosing well

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 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.

Common questions from Chippenham

Where does the DPC go?

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

Can I add other materials to my Chippenham delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.

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.

How soon can damp proofing be delivered in Chippenham?

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.
