Scope, assumptions, risk & value
Independent • No contractor commissions • Human-reviewed before anything is sent to you
We don’t just check whether the number looks high. We pressure-test whether the proposed drainage intervention itself makes sense.

Our view
DO NOT ACCEPT YET
The proposed works may improve collection of water reaching the retaining wall, but the information provided does not yet establish that subsurface groundwater is the primary cause.
What concerns us
Questions we'd ask before proceeding
Bottom line
We would clarify the source of the water and proposed discharge point before committing to the full scope.
Every DrainageCheck is reviewed by a Chartered Engineer, a qualified builder and a senior infrastructure project delivery expert.
Together, our review team brings more than 60 years of combined experience across engineering, construction, infrastructure and project delivery.
Chartered Civil / Structural Engineer
Brings engineering judgement to the proposed solution, drainage approach, site conditions, structural implications and technical risks.
Qualified Builder
Looks at the practicality of the proposed works, construction scope, exclusions and whether the approach makes sense on the ground.
Senior Infrastructure Project Delivery Expert
Pressure-tests the overall decision — scope, assumptions, risk, value for money and the questions that should be answered before you commit.
We don't simply summarise your quote. We challenge it.
Your DrainageCheck considers whether the proposed solution makes sense, what may be missing or unclear, what assumptions need testing and what you should ask before spending the money.
We don't undertake the drainage works, sell contractor leads or receive referral commissions.
The biggest risk is not the price — it is paying for the wrong intervention.
Does the proposed solution make sense?
Does the work logically address the problem you've described?
What's missing or unclear?
Are important items, exclusions or assumptions absent from the quote?
What assumptions need testing?
What does the contractor appear to be assuming about the cause?
Could there be a simpler approach?
Are there alternatives worth asking about before excavation begins?
Are there scope or pricing red flags?
Does anything warrant clarification or another quote?
What should you ask before accepting?
We'll give you practical questions to take back to your contractor.
If the proposed work is right, you can proceed with more confidence. If something important is missing, unclear or based on an assumption, you can find out before the excavation starts — not after.
