Delivering damp proofing in Brentwood

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

• With roughly 7h 48m of daylight in Brentwood around the shortest day, morning deliveries leave more working light for the job.
• Give us the full postcode for the drop point; deliveries around CM14 are priced to the exact address.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

How much will you need?

An extension in Brentwood with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Things to check before you order

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

Questions about damp proofing delivery in Brentwood

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.

Can I add other materials to my Brentwood 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.

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.

Do you deliver damp proofing to trades and homeowners in Brentwood?

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