Injection Grouting

Project Description: Charlotte Department of Transportation (CDOT) is committed to enhancing the driving, bicycling, and walk experience through planning, operating, and maintaining the City’s transportation choices for residents and visitors. An important component in the operation and maintenance of the transportation network is the maintenance of storm drainage systems and subsurface soils. Charlotte Storm Water Services is responsible for more than 3,800 miles of drainage pipe and over 150,000 associated inlets, outfalls and other systems. The Street Maintenance Division of CDOT serves as maintenance providers for much of this system in the right of way. Injection grouting provides a repair and maintenance method that is less disruptive than typical excavation methods.
The services generally consist of the provision of as-needed CHEMICAL GROUTING on storm water pipes, collars, subsurface voids and other areas as appropriate.
