Quantities: a worked example

An extension in Hoddesdon 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.

Getting the right damp proofing

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.

Laps and joints

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

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.

Delivering damp proofing in Hoddesdon

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• With roughly 7h 47m of daylight in Hoddesdon around the shortest day, morning deliveries leave more working light for the job.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
