  • Safety against groundwater ingress into the trench
  • Safety against slippage of single grains or grain groups
  • Safety against slip planes endangering the stability of the trench
  • System input and visualisation using absolute heights
  • Soil properties can be selected from an expandable database of common soils
  • User-definable water pressures
  • Variable design of output sheet including visualisation of Sum R, failure planes, penetration depth, support forces, earth pressures, etc.
  • Output table in graphics format
  • Adopted standard, program name and version can be included in the General legend
  • The prefix 'EC 7' can be placed in front of the 'DIN 4126:2013’ designation in the General legend
