Free LogPlot Alternative: Borehole Logs in the Browser

LogPlot by RockWare is excellent software with a price to match, and plenty of people need only a slice of what it does. This page is the honest comparison: what the free tools on this site cover, and where the commercial package still earns its keep.

What the free tools cover

• The Borehole Log Creator: layer depths, USCS soil types with standard colors, SPT values, water table marking, a scaled on screen log, and a clean printable record.
• The Cross Section Maker to correlate several logs into a section.
• SPT corrections for turning field blows into design values.

Everything runs in the browser with nothing installed and nothing uploaded: your data stays on your machine, results print to PDF, and every tool carries a Project bar that remembers your inputs and can assemble a report.

Where LogPlot still wins

LogPlot offers fully customizable log templates, lab data columns, project databases, and batch printing for hundreds of holes. Production drilling programs will still want it.

The verdict

For a handful of holes, a student project, or a quick log while the report software is on another desk, the free creator draws a presentable log in two minutes. Start with the links above; if you outgrow them, you will know exactly what to buy and why.
