corrosion for steel piles
 

corrosion for steel piles
can anyone tell me how to handle the corrosion issue for steel piles? thanks
couple of ways
1) contract out cathodic protection scope to third party. depending on the soil conditions, water level, salinity,grounding; they will propose sacrificial anodes or hook up to an above ground active corrosion protection system.
2) depending where you are, add 3 mm (1/8") corrosion allowance (in my case, northern alberta). we ground the pilecap reinforcement to one of the pile in the group.

thank you rtmote
how long does it take for 1/8"? why do you ground the reinf to one of the piles.
rate of corrosion varies depending on several factors including soil properties. see "nbs monograph 58, corrosion of steel pilings in soils" which you can download from this page of my website
