Scope

Michels Trenchless, Inc. rehabilitated 75 linear feet of a 60-inch corrugated metal culvert pipe with 1-1/2" of geopolymer mortar spray-in-place pipe (SIPP) lining.
The local highway department was responsible for the cleaning of the deteriorated culvert pipe, and removing rocks and the majority of debris from the pipe. The highway department also removed the conduits and wires from the pipe walls and communicated with the farmer about the project.
Michels Trenchless completed the preparation of the culvert by washing the walls and repairing all large gaps and holes within the pipe wall structure. The crew then hand-applied 17,500 pounds of geopolymer mortar to create a 1-1/2-inch SIPP liner within the pipe.
Michels Trenchless obtained the geopolymer mortar in dry form and mixed the material on-site prior to and during application. The jobsite was alongside a highway with cattle pastures on both sides of the culvert. The project was a trenchless repair under a crucial county highway in a rural community. The work was completed with minimal disruption to local traffic, residents and animals.
