Traffic on one of the island’s major streets was increased because of a major road realignment project. Robert Bowen inspected manholes there and saw that they were on the verge of collapse. According to Bowen, “Time was a very important factor and there was not a large budget for repairs/replacement. Because of new pavement and landscaping in the area, disruption of pavement, traffic, grass or utilities was not possible. The manholes were on t
Description
This project, completed in 2002, included 17 manholes located within the Yellowstone National Park. The manholes had significant deterioration from wastewater chemical corrosion. The structure pictured below was a rectangular vault.

Custom fabricated liner was manufactured by Poly-Triplex Industries, LLC to fit the size and shape of the box structure. Liner was saturated at the jobsite with a 2-part 100% solids epo
Boyd Lake Pump Station, located on the edge of Boyd Lake, is 6′ diameter and 20′ deep with severe problems with infiltration levels at approximately 40%. It was virtually impossible for the city to replace the pump station due to its proximity to the lake. The rehabilitation would require a system that could be successfully installed during active infiltration.

Description
This pipeline had previously been rehabilitated with an epoxy coating. Pinholes in the coating system had allowed sewer gases to continue to attack the host structure, resulting in failure of the coating and further deterioration of the pipe. Pipe has benches or shelves in the bottom forming a channel for the sewage flow.
Solution
Poly-Triplex Certified Installer bridged the flow in the channel with a sub-floor and allowed the sewage to flow underneath, sav
Description
Severe deterioration of the town’s sewer system called for a comprehensive manhole rehabilitation project that included permanent rehabilitation of 34 manholes. Baskerville Donovan chose to use the Poly-Triplex System to structurally enhance the structures and to stop the infiltration of groundwater.

Description
This 48″ diameter x 27′ deep structure was severely deteriorated with bricks falling out, near collapse, with infiltration sheeting down the wall. The structure was also leaning. Fulton County had offered the structure to several other companies, but no one wanted to attempt this structure.
Solution
Poly-Triplex Certified Installer pressure cleaned the structure and removed some of the fallen bricks. The other b
Description
Stormwater catch basin had cracks and crevices allowing infiltration of soil and erosion of the surrounding ground. Originally buried underground, the 30″ incoming pipe had been uncovered from excessive soil erosion. This structure was posing a problem, especially due to its proximity to an airplane runway.
Solution
The Poly-Triplex Liner System was installed and cured with hydrostatic head pressure by building a framework around the openings so that
