How much will you need?
An extension in Seaford with 36 m of cavity wall needs DPC in both leaves: about 3 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.
Picking the right product
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.
Questions about damp proofing delivery in Seaford
How soon can damp proofing be delivered in Seaford?
We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
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 I add other materials to my Seaford delivery?
Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.
Where does the DPC go?
Usually at least 150 mm above outside ground level, linked to the floor DPM.
