Getting the right damp proofing

Laps and joints

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

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.

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 Cowes with 12 m of cavity wall needs DPC in both leaves: about 1 roll in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting damp proofing onto your Cowes site

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Cowes needs a ferry crossing, so deliveries are quoted individually with the crossing included.

• On busy streets in Cowes, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

Questions about damp proofing delivery in Cowes

Is there a minimum order for delivery to Cowes?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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.

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

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.

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.
