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 Thetford: what helps

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

• With roughly 7h 40m of daylight in Thetford around the shortest day, morning deliveries leave more working light for the job.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
