Ground Screening for developers
Screen every site against the logs drillers already filed.
Send a list of sites, 5 or 500. For each one we pull the nearest measured well and boring logs, show the range of depths to rock they record, and give it a foundation-risk tier. Where there aren’t enough logs nearby, we say so.
Built on 343,355 well and boring logs that reached rock, the same records behind our open Ground Truth bedrock data.

Every tier comes with the logs behind it: distance, depth, source.
For every site on the list
The evidence, not just a verdict
- 01
Nearest measured logs
Distance, reported depth to rock, and the public record each one comes from.
- 02
Rock-depth range
The spread those logs show: shallowest, typical and deepest, not a single made-up number.
- 03
Foundation-risk tier
Driven pile OK, predrill likely or drilled pier likely, with the logs that put it there.
- 04
A “too few logs” flag
When the evidence is thin, the site is flagged, not filled in with a guess.
Foundation-risk tiers
Four answers, including “we can’t tell”
A screen is a compilation of measured records, not a prediction. Where logs exist nearby we show them: distance, depth and source. Where they don’t, the site is flagged rather than filled in with a model.
It’s a desk study, not a geotechnical investigation. It tells you where to look harder; borings and your engineer of record still come before design.
- Driven pile OK
Nearby logs consistently show rock deeper than the embedment you’re planning.
- Predrill likely
Some nearby logs show rock inside the embedment depth. Expect predrilling across part of the site.
- Drilled pier likely
Nearby logs consistently show shallow rock. Plan on drilled or socketed foundations.
- Too few logs
Not enough measured records nearby to call it. A ground check answers what the desk can’t.
How it runs
From a site list to a ranked screen
Step 1: Send your list
A KML, a CSV of coordinates or a list of addresses, plus the foundation type and embedment you’re planning, if you know them.
Step 2: We compile the logs
For each site, the measured well and boring logs within a set radius, checked for duplicates and bad depths.
Step 3: You get the screen
A spreadsheet with every site, its tier and the logs behind it, plus a short summary of the sites that need attention.
Step 4: Check the ones that matter
Where the screen is thin or the stakes are high, a ground check puts a measured depth at each foundation.
Who it’s for
Teams with more sites than borings
- Solar, carport & BESS developersRank a pipeline by foundation risk before you spend on borings.
- EPCs pricing a portfolioSee which sites are likely to need predrilling or drilled piers before you commit to a number.
- Site-selection and due-diligence teamsA ledge line on every site in the deal, backed by records you can check.
