Premium Reinforced Detectable Tape: ThorTec®
• Premier detectable tape for the "Last Line of
  Defense" against third party damage while also
   providing the ability to locate either inductively
   or conductively
• Patented reinforcing weave provides high tensile
  strength needed for plowed-in installations
• Multi-layer construction offers permanence of
  message, strength and locatability
• Shallow buried six to twelve inches below
  finished grade, ThorTec can be located reliably
  with even the least sophisticated metal detectors
• Wide-width detectable tape can be located
  up to three feet deep with proper
  detection equipment
• Middle foil layer allows for both inductive
  and conductive locating
• No ink extends to the edge of the tape providing
  the strongest bond between layers to
  prevent delamination
• Highly reflective foil surface is visible from both
  sides of tape to flash its warning to excavators
• Bold black letters include message and
  installation recommendations
