We are currently working on a rail project consisting of a retaining wall in which the current design consists of a concrete T wall supported by pipe piles (305mm). We are proposing a fully cantilever pipe pile wall (914mm). The owners first question was "We dont use steel for permanent walls due to corrosion".
Other than the contradiction using a concrete T wall supported by steel pipe piles vs. steel pipe piles (Both are steel), is anyone familiar with anti-corrosion techniques in which the owner can simply apply that does not require maintenance. At this point we have suggested filling the pipe with concrete, which appears to have convinced the owners, but any additional measures may be more cost effective.
The soils are classified as slightly aggressive.
Any asisstance is appreciated.

Michael,
I am working on a quay construction project. We are using 660mm diameter piles. The piles are covered by a black rubber coating and the from the top of the pile to a depth of -12m the piles are casted with reinforced concrete. In an environment exposed to seawater which is an aggressive corrosive environment, corrosion is prominent. There are 3 things which cater for corrosion : The black rubber coating, the difference between the internal diameter and external diameter of the pile and the reinforced concrete.
regards,
Vikram
