Before your Kettering delivery arrives

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Give us the full postcode for the drop point; deliveries around NN16 are priced to the exact address.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Picking the right product

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.

Questions about damp proofing delivery in Kettering

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 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.

Do you deliver damp proofing to trades and homeowners in Kettering?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

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

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.
