GEOCompass provides clear, code-based guidance on soil and rock testing requirements. Built by geotechnical engineers for consultants, contractors and clients who want clarity, not complexity.
Clear, consistent pages for the most common geotechnical tests, with when‑to‑use guidance, sampling notes and typical pitfalls.
Tests by Parameters
Start from the parameter you need (e.g., φ′, c′, mv, k) and see the tests that reliably deliver it.
Tests by Design
Begin with the design task (foundations, slopes, retaining structures, earthworks, pavements, offshore jackets) and get the geotechnical design parameters required with the associated laboratory test.
