Memphis, Tennessee: Sears Crosstown Box Culvert

location

Memphis, Tennessee

Installation Date

November 2017

owner

City of Memphis

scope

500 LF of 8’x10’ box culverts EcoCast

situation

In 2015, the City of Memphis’ Sears Crosstown box culvert system was under inspection. The inspection included the evaluation of twin 8’ x 10’ concrete box culverts, each a length of 500 linear feet, that are part of the Madison Heights drainage basin. The assigned engineering firm concluded that rehabilitation was needed for the system and suggested slip lining in the culvert as well as a spray-on lining system. After the full inspection, the system had severe corrosion, spalling and cracking. Inland Pipe Rehabilitation, LLC (IPR) was awarded the project in early 2017, due to the company’s expertise in box culvert repairs. 

Solution

IPR recommended its EcoCast geopolymer lining solution for the job and applied a minimum of 1.5” of geopolymer mortar. The mortar was used to recover and protect the steel structure as well as fill in voids, cracks and other defects that were allowing water infiltration into the culvert from the surrounding soil.

Conclusion

The city and the engineer approved the design and work began on the culvert early November 2017. Delays in the summer of 2017 due to excessive flooding in the area made dewatering the culvert impossible. Despite delays, the project was completed in early January 2018. The city of Memphis was pleased with the fast turnaround time and the box culvert system was reopened.  The city of Memphis has continued to assign IPR with new projects, including the rehabilitation of the upcoming AW Willis project.
