InSAR ground stability reports

See what your property has been doing for the last five years.

We use satellite radar to measure tiny, millimetre-level movements in the ground beneath homes and commercial buildings. That lets you see whether your property is stable, slowly settling, or shifting, often well before any cracks start to show.

How it works

Three steps. No drilling, no scaffolding, no one knocking on your door.

We work entirely from satellite data that already exists, so getting a picture of your property is simple.

01 / Observe

Satellites have been watching

Radar satellites have passed over your property every few days for years, quietly recording the exact height of the ground to the millimetre.

02 / Analyse

We measure the movement

We process that long history to track how much the ground beneath your property has risen or sunk over time, and how steady it has been.

03 / Report

You get a clear answer

A plain-English report that shows whether your property has been stable, how it has changed, and whether anything is worth a closer look.

What you get

A report anyone can read, not a spreadsheet you can't.

Every report starts with a clear answer in plain language, then shows the measurements behind it. Here's an example of what you'd receive.

Who it's for

Made for everyday property owners, on both sides of the door.

Residential

Homeowners & buyers

For peace of mind, before a purchase, or when you've noticed a crack and want to know whether it's the house moving or just the paint.

  • Houses, flats and the land they sit on
  • Pre-purchase and pre-sale checks
  • After nearby works, trees or a dry summer
Commercial

Property & facilities teams

For landlords and managers keeping an eye on a building or a portfolio without booking surveys for every site, every year.

  • Offices, retail units and warehouses
  • Managed estates and multi-site portfolios
  • Routine monitoring between formal surveys
Accuracy & method

Measurements you can trust, explained without the jargon.

The technique is called InSAR, short for interferometric synthetic aperture radar. In simple terms, satellites bounce radar off the ground and measure the tiny changes in distance between each pass. Stack up years of those passes and you can spot movement of just a millimetre or two.

It's independent, repeatable, and built on the same European Space Agency data that academic and government studies rely on. We don't guess from photos. We measure.

Plainly stated

What this is, and what it isn't.

A SolidStrata report is a genuinely useful early signal, though there's a point where it hands off to a professional - and we'll always tell you when you've reached it.

+ What it is

  • An independent, satellite-based view of how the ground and your building have moved over time.
  • A clear early indicator of stability, settlement or uplift, written to be informative and easy to understand.
  • A way to keep an eye on a property without booking a survey for every check.

− What it isn't

  • Not a structural engineering survey or a building inspection.
  • Not a legal certificate, valuation, or substitute for a qualified surveyor.
  • Not a diagnosis of why movement is happening, or a guarantee about the future.

If our analysis shows movement that could matter, we'll say so plainly and recommend you commission a qualified structural engineer or chartered surveyor. SolidStrata helps inform that decision. It never replaces it.

Questions

Good questions, plainly answered.

Do you need to visit my property?
No. Everything is measured from satellite data that already exists, so there's no appointment, no equipment on site, and no disruption. We only need your address.
How far back can you see?
For most properties we can look back five years or more, drawing on radar data collected since 2015. The longer the history, the clearer the picture of how your ground behaves through wet winters and dry summers.
What does the report actually tell me?
Whether the ground and building have moved, by how much, in which direction, and whether the trend is steady or changing. It leads with a plain-language summary, then shows the measurements and a deformation map behind it.
Is this a structural survey?
No. It's informational, not a structural engineering assessment. It's a great early indicator, but if it flags something, we'll point you towards a qualified surveyor or structural engineer for a formal inspection.
What kinds of property can you cover?
Residential and commercial buildings, including houses, flats, offices, retail units and warehouses. Built for everyday property owners, using the same proven technology relied on across the mining and heavy-industrial sectors.
How accurate is it really?
Millimetre-scale. The technique is well established in science and engineering, and we use the European Space Agency's Sentinel-1 radar data, the same source used in published research.
