Download Roclab [updated] Jun 2026

If you are looking to , it is important to understand that this specialized geotechnical software has evolved. Originally developed by Rocscience , Roclab was a free tool used globally by engineers to determine rock mass strength parameters based on the Hoek-Brown failure criterion.

⚠️ Always download from the official source to avoid malicious or outdated files.

Calculating the constants for the Generalized Hoek-Brown criterion manually is tedious. It involves assessing the Geological Strength Index (GSI), the rock mass disturbance factor ($D$), and the intact rock properties ($ci$ and $mi$). A small error in these calculations can lead to significant discrepancies in slope stability analysis. By using Roclab, you remove the risk of calculation errors. Download Roclab

Some Roescience free tools may ask for basic information:

One of the most appealing aspects of Roclab is its price tag: Unlike expensive finite element analysis suites, Roclab is provided by Rocscience as a freeware tool. This accessibility makes it an essential addition to every geotechnical engineer’s digital toolkit, regardless of company size or budget. If you are looking to , it is

For very poor quality rock masses (GSI 15-25), the original Hoek-Brown criterion may produce unrealistic tensile strengths. Use the option and check the “Limit tensile strength” box.

Searching for is your first step toward more accurate, defensible rock mechanics designs. As a free, professional-grade tool, it removes the guesswork from the Hoek-Brown criterion and provides clean, exportable data for your numeric models. By using Roclab, you remove the risk of calculation errors
