Stabilization Methods

Selection Criteria:

  • Subsurface conditions & potential modes of failure
  • The present & required topography
  • Physical constraints – property lines or buildings
  • Consequences of failure
  • Availability of materials, equipment, & expertise
  • Local performance history
  • Aesthetics
  • Time required for construction
  • Cost
