2D and 3D slope stability software in one workflow
TSLOPE slope stability software lets you build or import a project once, analyse it in 2D and 3D, and compare results without rebuilding the model between separate programs. Bring in existing GIS, terrain, CAD and 2D slope models, keep the engineering assumptions visible, and move efficiently from site data to a reliable factor of safety.
Full 2D and 3D analysis from US$175/day, with no annual commitment required.
Move from existing project data to slope stability analysis with less rework
TSLOPE is designed around the way geotechnical projects actually develop. Start with a known 2D model, mapped GIS information, terrain data or engineer-defined geometry, then test the interpretation in two and three dimensions.
Keep mapped site data connected
Transfer contours, geological surfaces, boreholes, boundaries and slope data from QGIS into the TSLOPE workflow.
Extend analysis without starting again
Import a Slide2 or SLOPE/W project and extrude the section into 3D, or create a 2D case from a 3D model.
See why the result changed
Inspect failure geometry, forces, sliding direction and calculated behaviour rather than treating the factor of safety as a black-box output.
Pay for the access you need
Build and edit models without an active licence. Choose Day, Week, Month or Year access when you need to solve.
Geovert
“The ability to model the slope in 3D was particularly useful as this provided a more realistic representation of the failure geometry and helped optimise the anchor spacing to the benefit of the client. ”

Build now. Solve when you're ready.
With TSLOPE, you can build, import and modify your slope stability model without an active licence.
You only need to activate a licence when you're ready to solve for the factor of safety.
Continue developing your model between licence periods, then activate another licence when you need to run further calculations.
Evaluate TSLOPE against your current slope stability workflow
Import an existing model or use your own site data, run 2D and 3D analyses, and compare the results directly. Every paid licence includes the same full capability, starting at US$175 for a Day licence.
