Microtrenching

Microtrenching is a minimally invasive technology that enhances the ability to place fiber optic cable quickly and cost-effectively in challenging construction environments including existing roadway beds and dense urban areas. CertusView’s Microtrenching process includes:

  • Cutting a narrow trench in the existing surface to create a void;
  • Evacuating debris;
  • Laying cable;
  • Flowing a non-shrinking composition into the void; and
  • Applying a topping material.

The patented process involves making a narrow cut in the existing surface and then removing the debris from the trench at the same time using a specially designed vacuum system. Fiber conduit is then placed in the trench with a backfill of custom flowable material.

This new method:

  • Limits damage to existing facilities by using a narrow shallow trench;
  • Minimizes disruption of existing traffic patterns, as vehicles can traverse the trench; and
  • Permits thousands of feet of cable to be placed in one day by using a tractor with a saw and a vacuum truck.
