Corroded pipes are identified and a plan is developed to rehabilitate them with minimal access points and disruption.

A recorded video of the interior of the pipe helps the team assess existing conditions and verify the plan.

For most pipe materials, a drag scraper is run in both directions to remove corrosion from a tuberculated pipe, restoring the original pipe diameter.

Depending on the age, material and condition of the pipe, it is water jetted at varying pressures to clear away any remaining scaling and dirt left on pipe walls.

A recorded video verifies the pipe is sufficiently cleaned and the surface is prepared.  If defects in the system are apparent, they can be patched in preparation for the lining process.

Our state of the art robotic technology spin casts the epoxy directly onto the pipe walls. At all times we are monitoring the mix ratio and temperature of the epoxy and the speed at which the spray head is travelling through the pipe, which is how the desired thickness is achieved.  A final camera inspection verifies the results.
