Project Profile

Materials & Equipment CSP Aluminized Steel Type ll Spiral Rib Pipe
Location: Fairmount, ND
Owner: North Dakota DOT
Contractor: Olander Construction
Consulting Engineer: North Dakota DOT
Application: Concrete pipe rehabilitation
Special Project Elements: The liner pipe was installed and the annulus was grouted through internal ports. The installation process minimized the time required to rehabilitate this existing pipe.

Why corrugated steel pipe from TrueNorth Steel?

Existing concrete pipe joints were misaligned and leaking both soil and water. Spiral rib CSP was chosen because of its Manning’s “n” = .012. This allows for maximizing hydraulic capacity.
