Damp Proofing & Membranes delivered to Doncaster

Choosing from our damp proofing range

• Radon barriersGas-resistant membranes for areas that need radon protection.
• Weep ventsFor drainage and ventilation at the base of cavities and over trays.
• DPM sheetingHeavy-gauge polythene membrane under concrete floors.
• Cavity trays and stop endsTo direct water out of the cavity over openings.

Quantities: a worked example

An extension in Doncaster with 36 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.

Before you order damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

Delivery to Doncaster: what helps

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Doncaster 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.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Damp Proofing & Membranes questions

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

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.

Is there a minimum order for delivery to Doncaster?

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.

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building control requires radon protection in new buildings and extensions.

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.
