Re: Corrosion in reinforcing steel in slabs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You should also investigate whether you will need a cathodic protection system.   We were involved in a number of homes which were founded over salt ponds and eventually had serious problems.  The Manhattan Beach pier was an example of severe corrosion and electrolyses problems in the 1980's.   Wiss, Janney provided a very good report on the problems and solutions to that structure.

Does anybody have a good reference (books, articles, catalogs, web sites, etc.) regarding some methods to repair elevated slabs whose rebars are severely corroded? Is there any commercial product or technique to restore the structural capacity of the slab, other than demolishing and re-building? Thanks in advance.
