THE GROUND. THE CONTEXT. THE NEXT STEP.
Understand the ground beneath your home.
Soil maps are complicated. Your next step should not be. See mapped shrink–swell properties, weekly county drought and the evidence that is still missing.

ONE QUESTION. THE RIGHT STARTING POINT.
What would you like
to understand?
Choose the evidence you have. Each tool explains its inputs, shows what is missing and gives you a useful next step.
LOCATION
Check an address
Confirm a contiguous-U.S. location and see mapped soil evidence, coverage gaps and dated county drought.
Start a location checkCOMPARISON
Put locations side by side
Keep up to three location reports aligned without turning regional data into a safer-house ranking.
Open the comparison boardONE VALUE
Understand an LE number
Start here with one linear-extensibility value. See the screening boundaries and what the number does not mean.
Interpret one valueSOIL LAYERS
See the missing depth
Enter several layers from one profile. Separate reported values, unrated intervals and a transparent arithmetic summary.

Two locations.
Different ground. Better questions.
Keep up to three locations together. Compare soil evidence, missing depth and the dates behind county drought — without inventing a safer-house score.

Visible limitations
No invented rankingWHAT MAKES A REPORT USEFUL?
The evidence.
And its limits.
A “High” soil class is not a diagnosis. A blank record is not a low result. Your report keeps the distinction visible.

100 cm
Inspect reported layers and gaps in the upper 100 cm. The depth illustration here is not a measured soil profile.
A date beside every trend
Put drought in perspective.
Compare published county weeks. Distinguish a fresh check from an old snapshot, and percentage points from property risk.

Less guesswork. Better questions.
Read the evidence
Keep soil properties, county drought and missing information in separate panels.

Add dated observations, save a snapshot and prepare focused inspection questions.
FIELD NOTES
Understand the result
before you act.
THE GROUND
Expansive soil: what a map can tell you
Clay is a clue, not a diagnosis. Learn which soil properties matter, where the map stops, and what to ask before making a repair decision.
Read the field noteCHANGING CONDITIONS
Drought and foundations: keep the scale in view
A dry county and a moving foundation are not the same measurement. Use the weekly trend as context, without mistaking it for a sensor under your house.
Read the field noteBEFORE YOU BUY
Soil map vs. geotechnical report: what is the difference?
Use the right evidence for the question. A regional soil survey and a site investigation do not describe a home at the same level of detail.
Read the field noteCan this tell whether my foundation is safe?
No. It shows mapped soil properties and regional drought context. It does not inspect the structure, measure movement or determine whether repair is needed.
What happens when data is missing?
The report distinguishes an unavailable service, missing coverage and an unrated soil property. None of those becomes a low class or zero drought percentage.
Do I need to create an account?
No. Checks do not get public address URLs. The report and notebook can be saved in this browser only when you choose, or exported to your device.
Is the drought percentage about my property?
No. It is the share of the surrounding county in a drought category or worse. It is not a soil-moisture reading beneath your house.
FROM A QUESTION TO A CLEARER PICTURE
Know the evidence. Know your next step.
Start with the ground, add your observations and keep the two separate.
