Research Edition
Geotechnical field and lab analysis, made simple for universities
Type your readings. SoilLab gives you standards-based results, charts, soil classification and exports you can cite in a report or a paper.
Free for students, lecturers and researchers. No setup, no approval queue.
Seven field tests
SPT, CPT, vane shear, dilatometer, pressuremeter, plate load and DCP — with depth profiles drawn as you type.
Nine laboratory tests
Atterberg limits, grading, specific gravity, compaction, CBR, permeability, shear box, consolidation and triaxial.
Classification you can check
USCS and AASHTO groups with the formula, the numbers you entered and the standard shown for every step.
Citable exports
CSV, AGS 4.2, JSON, publication figures, an academic PDF and a reproducibility bundle.
Methods and references
Every correlation lists its author, year, assumptions and BibTeX entry.
Built for teaching
Each module has a worked example you can reveal or hide, so classes follow the maths, not the software.
Three steps, nothing else to learn
1. Sign in
Use your university email address.
2. Pick a test
Every field and lab module sits in one side menu.
3. Export
Take the results, figures and citation with you.
