The flood infrastructure you already own

Every commercial portfolio has spaces hiding in plain sight: margins, rooftops, courtyards. These could be absorbing surface water instead of sitting idle. We help you find them, model their value, and verify their performance to standards insurers and lenders trust.

What we do

Ordinary spaces. Extraordinary potential.

While insurance costs for climate-exposed property are rising, every commercial portfolio has thousands of square metres doing nothing.

Nature-based solutions work through accumulation. A rain garden slows runoff, permeable surface absorbs it, and green roofs can retain it. Each intervention is small. Together, across a portfolio, they add up to something insurers can price.

The problem isn't the solutions. It's visibility. No one's been mapping this potential, modelling its value, or proving it works. Until now.

Find

Scan your portfolio for spaces with adaptation potential: the dead zones that could become your best protection.

Quantify

Model how specific interventions would reduce flood risk. Property by property and portfolio-wide. Numbers insurers want to see.

Verify

Verify performance to auditable standards. Evidence that translates into coverage decisions: not just reports that sit in a drawer downloads folder.

Solutions

We cover the range of nature-based interventions: sustainable drainage, permeable surfaces, green roofs, water retention features. Each one modelled, documented, and verified to a standard that makes a difference at renewal.

Put your portfolio to work against rising premiums

Here's something worth knowing: most insurers allocate annual bursaries for flood risk management on commercial portfolios.

That money often goes unspent because there's no clear path from we should do something to here's the verified outcome.

Plain Site provides that path. We help you identify where to intervene, quantify what it's worth, and prove it worked.

Curious whether your insurer offers risk bursaries? We can help you find out.
