How much longer will a PEARSON PILE last compared to concrete?
It is hard to be definitive about the life expectancy of a concrete pile – fresh water performance is better than salt water performance; freeze/thaw cycles will deteriorate the concrete more rapidly; dynamic loading both in driving and lateral force can fail the concrete; the steel reinforcement, while epoxy coated, will corrode rapidly if the concrete has any compression or tension cracks; an unreinforced concrete pile must be significantly larger in section, but less prone to fresh water damage. That was sort of a long answer – in short: The composite pile has a probable life of 100 to 300 years, exclusive of the surface finish, while the concrete pile has a probable life of 15 to 20 years. I am thinking that it would be best to pump out all piles after install into bottom, removing water and allowing time to dry out. Then use a cap design that will seal inside area air tight, moisture tight. That it would be better to maintain the inside of the pile free from moisture? There is abs
