During the testing of circular grit chambers in a wastewater treatment plant under construction, serious leaking problems were discovered prior to project completion. After meetings with the Owner, Design and Construction engineering firms, painting contractor and coatings manufacturer, the decision was made to apply 80 mils of pure polyurea to various concrete surfaces. This presentation, through the use of photo images taken during remediation, describes the nature of the problem and how it was solved.
