DINO Six Sediment Removal

October 2016

What's on the sonar?                                                                                                            

Upcoming Webinar..... October 20, 12:00 - 1:00 pm CT

Inspecting, Repairing and Preserving Corroded Steel Sheet Pile Dock Walls Below the Water Surface in the Dry

Amazing technology developed in Europe.  Now used by Roen Salvage Company, a national marine contractor in the United States.  A three sided box is placed alongside the corroded wall and the water pumped out.  After the water is out the wall can be examined, measurements taken, repairs made, and then epoxy coated for many years of useful life.  All at a fraction of the cost of replacement.  Better quality control than doing the work underwater.  The dock can stay in operation.  Much faster than any other method .... more than a mile of wall in less than six months.

A continuing education certificate will be provided to attendees that may need CEUs for professional engineering re-certification.
