84" Wabash Culvert Repair
- Location Indiana
MethodsCofferdams Bypass pumping Dewatering Confined spaces
Michels rehabilitated a deteriorated culvert beneath the coal pile of an active power plant. Joint repairs on the culvert were completed prior to the application of a carbon fiber reinforced polymer (CFRP) wrap to reinforced and strengthened the existing culvert structure.
Michels self-preformed the installation of gravel access roads, 50-foot cofferdams, up to 18" bypass pumps and the dewatering of 4 million gallons of water to keep the work area dry from ground water in the repair process. Evacuation of the area was not possible due to the location of the coal pile above the culvert.
