Pedestrian Underpass for a Rail Road


United States, Fridley, Minnesota


Hancock Concrete Products Co. Inc.

The Situation:

In the construction of a railroad line, the design required a watertight pedestrian underpass. Therefore, the box culverts that were used to construct this pedestrian underpass required a sealant that could meet the project specifications.

The Solution:

To provide a watertight seal between box culverts, CS-102 butyl sealant was used. 24” wide ConWrap CS-212 was used to prevent water and soil going into the joint. In addition, 48” wide ConWrap CS-212 was used to provide corrosion resistance and added waterproofing to help insure a watertight pedestrian underpass to meet the project specifications.

Sealant Application:

  • Box Culverts

ConSeal Products Used:

Applicable Industry Standards:

  • ASTM C-990
  • ASTM 877 Type III
