Working out quantities for your Harwich job
An extension in Harwich with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Things to check before you order
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.
Questions about damp proofing delivery in Harwich
Do you deliver damp proofing to Harwich?
Yes. We deliver across Harwich, including CO12. Harwich is inside our standard mainland delivery area. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.
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.
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.
Is there a minimum order for delivery to Harwich?
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.
