Damp Proofing & Membranes: choosing well

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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

An extension in Milford Haven with 16 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.

Your questions answered

Do you deliver damp proofing to trades and homeowners in Milford Haven?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

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.

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.

Is there a minimum order for delivery to Milford Haven?

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.
