Concrete-Oil Terminal Repairs


Concrete PitConcrete Pit RepairConcrete Pit Repaired




Pipeline underground of railroad tracks built 50 years ago with wooden timber.

Timbers failed.

The challenge…

How to protect the pipelines without having to remove them and shutdown the terminal.

Vic truck was used to remove mud and sludge from 50 years of work. Install new gravel base and sump pit.

Install slab over area with turndown so new concrete walls could be cast in place leaving old wooden timbers in place.

This allowed terminal to continue normal operations and production.

The end result…. a new long lasting containment area and safe work conditions.

This old bridge needed replacement.



W.J. Rapp Co. Inc. was asked to reposition the bridge, and stabize it using oak timbers. They also built crushed-rock entrance and exit ramps to the bridge.
