Find it. Seal it. Prove it.
Five stages, the same on every project, from the first inspection to a documented handover.
- 01
Inspect
Inspect the site and identify visible symptoms, failure points and moisture conditions.
- 02
Diagnose
Determine where the water is entering and what is causing the failure.
- 03
Specify
Select the appropriate waterproofing system and materials for the condition.
- 04
Apply
Prepare the substrate and execute the agreed waterproofing system carefully.
- 05
Verify
Test where applicable, document the completed work and hand over the project clearly.
Don’t just take
our word for it.
We document the important stages of the work so you can see what was found, what was done and how the project was completed.

Every project aims for the full chain. Where a stage does not apply, we say so rather than papering over it.
