After reading in GR about how the man used rebar spiked in the ground then zip tied to the pvc pipe I had to share what test I had done over the years for a company about the rebar. They wanted a cheaper way and different to coat it, so here it goes.
1. all rebar was sand blasted
2. then brushed with asitone (sp)
3. dipped in plastic coat, dried, times 10
Because the earth is -/+ acid and water rust metal they had a bang up job! The metal was used in a water plant and after welding we had to go back and recoat which was not a problem.
Enjoy,
William
Sorry I did nto say but every month we had to go back in and inspect all weld joints and longer runs of bar for 4 yrs it held till my company was out bided. When I read about the rebar in the ground it remind me of that contract we had. Leasted I can say my stuff held . As of now I don't know any more people in the plant that I use to deal with as is about normal in todays world.
Another thing I forgot to say is when welders making there bead remember to cool down the bar where the plastic coat, we left 4' from the weld exposed metal.

I am not english I am Native American.
Thats great William but last time i was in the USA the official language was english, which these days is divided into two main sections British english and American english. The english I use is Australian english whichis only a small variation on British As this is an international forumi would counsel aginst using local idioms (language variations) as the idea of writing anything is so that other people can understand you. If i use a British english word that i know has an American english equivalent i put the other word in brackets after it ie. sleepers(ties).
