RocLab remains available through various trusted software repositories. To obtain your free copy, follow this guide:
RocLab 1.0 is a legacy version (released in the early 2000s). Rocscience has since released RocLab 2.0 (a free, modernized version with an updated interface and more features).
: Determines tensile strength, uniaxial compressive strength, and deformation modulus. Roclab 1.0 Download
Click the picker. Assess your rock mass structure (e.g., blocky, disintegrated) and surface joint conditions (e.g., very good, poor). The intersection on the GSI chart yields your index value. Estimate the Disturbance Factor ( ) based on your excavation method—ranging from for undisturbed TBM tunneling to for poorly blasted open-pit mine slopes. Step 3: Define the Stress Range
Because most traditional geotechnical software (like Slide2 or Phase2) historically relied on linear Mohr-Coulomb parameters, RocLab automatically calculates: Cohesion ( The intersection on the GSI chart yields your index value
Often, this version is regarded as a classic tool that provides essential calculations without requiring a subscription. Where to Find the RocLab 1.0 Download
| Pros | Cons | |------|------| | ✅ – no trial limits | ❌ Outdated UI – looks like Windows 98 | | ✅ No internet required after install | ❌ No SI units toggle (uses MPa, but no auto-conversion for stress) | | ✅ Very fast & stable | ❌ Lacks newer features – no anisotropic criteria, no intact rock strength charts (added in v2.0) | | ✅ Accurate Hoek-Brown (2002 edition) | ❌ No support from Rocscience | | ✅ Perfect for learning the criterion | ❌ Does not handle GSI > 75 or D factor well (improved in later versions) | RocLab automatically calculates: Cohesion ( Often
RocLab precisely calculates overall rock mass metrics, including: Total rock mass tensile strength ( σtmsigma sub t m end-sub Uniaxial rock mass compressive strength ( σcsigma sub c Global rock mass strength ( σcmsigma sub c m end-sub Deformation modulus ( Emcap E sub m 4.

It is important to note that . While Rocscience offered to keep RocLab 1.0 available as a free program for non-commercial educational use, the company has since focused its development efforts on a more powerful successor called RocData 4.0 (and beyond).
