The rehabilitation of the WWII era Point Protrero Wharf in Richmond, California, would be not only a challenging and labor intensive undertaking for the contractor and specifying consultant, but also extremely high-profile. Earlier in the year, American Honda announced plans to shift the import of nearly 150,000 vehicles per year to the Richmond marine terminal.
The specifying consultant, Sugiarto Loni, SE, with design engineering firm Liftech Consultants, Inc. required a high-performance solution to strengthening 96 structurally damaged concrete piles using a form and pour method. In addition, the repair mortar needed to offer large volume placement capabilities and shrinkage compensating properties while providing an application range of 1" to 8" in thickness.
Based on the conditions provided by the specifier, Dayton Superior recommended their Civil/Structural FPX over a non-shrink grout product. The Civil/Structural FPX would allow for the greatest resistance to spalling and disintegration, which was critical on this project. A one-component, polymer modified cement based-material enhanced with a corrosion inhibitor and a coarse aggregate, Civil/Structural FPX can be placed to a depth of 8" and provide a higher level of repair while withstanding the extreme conditions of a wharf environment.
“Because we used the Civil/Structural FPX, a pre-engineered product, supplied in 48 bulk bags, our five man crew saved approximately 120 hours of labor which translates into a savings of $9,000,” said Chris Ellis, PE, project manager for Vortex.
