Philadelphia, PA: Slurry Wall Construction of Philadelphia Refinery

Project Description

Description of Work:

A small soil-bentonite slurry wall was installed to stop an oil sheen from appearing on the Delaware River.  The engineered soil-bentonite backfill consisted of borrow soils and a contaminant-resistant bentonite.  The slurry wall was constructed in contact with a steel sheet pile wall and keyed into an underlying aquiclude at a depth of less than 20 ft.  Numerous pipelines, dock facilities, and buildings interfered with the alignment and were crossed during the work.  Floating booms were used to limit spillage from leaks in the sheet piles.
