Wall and stability monitoring

Maptek solutions help improve safety by early detection of surface movements and moisture leakage in highwalls and tailings dams.

Maptek laser-based monitoring solutions allow operations to safely survey pit highwalls and dam walls from remote standoff. Stability analysis can be conducted on high resolution I-Site laser scans and accompanying digital imagery.

Laser scanning and modelling tools provide a safe and reliable solution for mapping tailings dams to manage risk. Repeated mapping allows close management of the integrity of tailings dams and shows regulatory bodies that safety issues are being considered.

The Sentry laser-based wall monitoring system allows operations to track surface movements and analyse deformation trends. I-Site laser scan data is combined with sophisticated Sentry software to track and analyse movement over time.

Wall monitoring data enables operations to gain a better understanding of how materials behave during mining and sites can apply I-Site laser scanners to all survey, monitoring and conformance reporting using Maptek spatial solutions.


  • Reliable and repeatable mapping of highwall and dam structures
  • Apply 3D topographic model to hydrographic modelling and failure simulations
  • Survey tailings storage facilities, capturing structures and surrounding areas
  • Conduct deformation analysis and plan mitigation work
  • Maintain audits of the integrity of structures for regulatory reporting
  • Diagnostic tracking for making reliable engineering decisions
  • Track changes in moisture and identify seepage as predictor of potential failure
