Before your Egham delivery arrives

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

• Give us the full postcode for the drop point; deliveries around TW20 are priced to the exact address.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

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.

Working out quantities for your Egham job

An extension in Egham with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Ordering damp proofing for Egham: FAQs

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

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.

Can I add other materials to my Egham 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.

Where does the DPC go?

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

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.
