TSLOPE 2D + 3D SLOPE STABILITY SOFTWARE Built for geotechnical engineers working across civil, mining and complex slope projects.

Solve slope stability faster,
in 2D and 3D

Use an existing slope stability model or build a new one from scratch, then solve for factor of safety in 2D or 3D within a single workflow.

Get to your first result in minutes, compare 2D and 3D outcomes directly, and iterate quickly without switching between tools.

Get to your first result in ~10 minutes.

Real project application Karaka Bay coastal slope assessment

From real site data to defensible 3D and 2D results.

Historical landslide evidence, terrain, borehole information, geological interpretation and groundwater conditions were brought together in one TSLOPE model. A 2D section was then extracted from the 3D model for direct comparison.
