GeoSpray® Geopolymer Mortar: 13 Mile Road Culvert Rehabilitation

Project Overview
As part of the 13 Mile Road Rehabilitation from Haggerty Road to Halsted Road, twin parallel 78” CMP culverts were to be relined with geopolymer mortar.  Each of the twin culverts are approximately 200 linear ft.  The culverts are used to carry the flow of Seeley Drain under 13 Mile Road immediately east of Haggerty Road.  

The project involved the use of state funds in a cost sharing situation with the City of Farmington Hills. The design requirements therefore must follow Michigan Department of Transportation (MDOT) standards and also be bid through the MDOT letting process.


Solution
The design consultant, HRC, evaluated and selected a geopolymer lining solution after evaluating other rehabilitation options.  The CMP culverts were experiencing moderate to severe deterioration with 95% loss of steel in some sections.  A benefit of the site was the twin culverts allowed for diversion pumping of the active flowing Seeley Drain so that one pipe could be repaired while the other was used for complete flow diversion.  Milliken Infrastructure's GeoSpray geopolymer mortar was the selected material for repair. The geopolymer mortar was hand sprayed by Inland Pipe Rehabilitation in Detroit working as a subcontractor to the General Contractor, Dan’s Excavating.  An advantage of the GeoSpray system is the flexibility in application which allows the contractor to optimize the process to meet client expectations. Centrifugally casting, hand spraying, troweling, and pouring are all options. In this project, hand spraying was chosen by the contractor to improve efficiency of the daily work based on site conditions and access.
