Delivery to Rochester: what helps

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Give us the full postcode for the drop point; deliveries around ME1 are priced to the exact address.

Getting the right 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.

Quantities: a worked example

An extension in Rochester with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes in Rochester: questions

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

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

Where does the DPC go?

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

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.

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

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.
