Commercial waterproofing for newbuild properties
Keep your building protected against water with Cannon clarke
Commercial waterproofing for newbuild properties
Waterproofing failures are one of the leading causes of delays, remedial works, and post‑completion disputes in commercial construction. Hidden moisture can compromise membranes, insulation, substrates, and structural elements — often long before visible signs appear.
Our diagnostics help you:
- Prevent costly water ingress issues
- Avoid mid‑project delays and rework
- Protect your margins and programme
- Reduce the risk of insurance complications
- Deliver a reliable, compliant final product
When waterproofing fails, everyone pays. When it succeeds, everyone wins.

Our Process
Survey
We start by conducting a thorough survey of the space you want inspected. There's usually a fee for our initial consultation.
01
Scoping discussion
We collaborate with you to marry your objectives with our findings from the survey. We’ll discuss how you want to use the space when it’s finished and the best way of achieving your vision.
02
Design
Once we have the physical specifications, and your input on your requirements, we’ll design a system that works for you.
03
Approval
We’ll send you a specification, together with a report which explains the technical aspects. We’re happy to chat through this with you and make any changes you’ve identified.
04
Work begins
With an approved plan in place, we’ll get to work on the date we’ve agreed between us.
