Project Challenges
• 450 linear feet of drainage channel had developed voids under the concrete panel
• Water in parts was traveling under the panels rather than over during rain events
• The college was seeking a cost-effective solution to extend the life of the drainage structure and avoid the cost of rip and replacement.
Design Approach
• Injections were placed on a 4-foot grid along the bottom of the drainage structure as well as halfway up the side walls.
Project Support
• Eagle Lift worked as a subcontractor under Three Peaks Construction who was contracted to install an epoxy overlay over certain areas of the channel after the voids were filled
• Preconstruction meeting with college maintenance staff and contractors to ensure work did not interfere with school operations.
Results
• Voids under the area of concern were filled with material usage coming in at 25% under budget
• RCC was able to use cost savings to proceed with additional repair projects that they did not anticipate having the funding to complete.
