Which service is right for your project?

There are a number of factors that come into play when choosing a trenchless solution. We’ve developed the following chart as a rough guide. For an accurate, professional assessment, please contact a Crossing Group company.

Factors to consider:

  • Crossing Length
  • Product Line Diameter
  • Soil/Formation Type
  • Required Precision (Alignment and Grade)
  • Product Line/Casing Material (eg. Steel vs Polymer)
