Saltwater Corrosion
Saltwater Corrosion
(OP)
I have a project where a contractor has questioned using helical anchors in a coastal region. There is a high water table at the site, and the geotech has recommended helical anchors. Anyone experienced with saltwater corrosion of helical anchors? The site is several miles inland.

I think the concrete caps on the anchors could be extended to below the water table fluctuation line, and corrosion be completely taken care of even if there is salty water at the site. One installer of the anchors believes the design life of the anchors to be in excess of 50 years without modifications to the concrete caps (part of the anchors experiencing saltwater table fluctuation).
