ufer ground

[NolaTigaBait]

why would you say in this case that rods would be more effective?....it seems that if i used a ufer ground, there would be more surface area in contact with the ground....the reason why i asked about the driveway is b/c in the future lets say they decide to re-do it or take it out, im sure they would destroy the electrode in the process...just thinking out loud here

Well I'm thinking that the moisture level will be low , given the shallow depth ,.. Heck I'm not even sure it would be considered a Ufer ,..and depending on the resistivety of the earth rods can have a lower resistance than even a Ufer .. From the link I posted

At a number of sites, separate driven
ground rods were also installed and measured. It was found that in soils of lower
resistivities, i.e., good grounding sites of 5000 Ω-cm or less, rods driven directly
into the soil had lower resistances than encased electrodes. The explanation is that
these soils have resistivities lower than that of typical concrete, hence there is no
advantage to encasement.

Forget what I said about moisture levels ,.. I see now that you are below moisture level

well, i'm not really sure what to do here..i can drive 2 rods and be done with it or i can drive the rods and connect to the rebar....it's a fishing camp about 20 feet from the water, so the ground is pretty moist...

If you connect to the rebar as a CEE then you dont need to use the ground rods.

yeah, i know but.....in this case the driveway may not be installed to well after the final inspection!....

Most driveways don't have rebar in it either.

 

[NolaTigaBait]

i'm well aware of that....i was going use 20 feet of #4....the reason why i said rebar was that it was easier to describe what i was doing

 

[NolaTigaBait]

oh and i forgot.....JEEEEEEEEEEEEZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZUUUUUUUUUUUUUUUUUUUSSSSSSSSSSSSSSSSSSSSSS christ no rebar..........JJJJJJJJJJJJJJJJJJJJEEEEEEEEZZZZZZZZZZZZZZZZZ

What is the purpose of this statement if it is inaccurate and there is no driveway. Jeeeeezzzzzz-- you have to drive the ground rods-- what's the problem? You can always add the CEE-- if they remember to call you when they pour the driveway.

You are driving me nuts-- Of course I don't have far to go.

rebar .....5 letters
20 feet of #4 bare ground.....20 letters...
i guess i was being lazy.....should have known it would come back and bite me in the rear on this forum

Karl,

What do you mean by "future use"?

Say you pour a slab for a detached building, shed,storage,etc.
Here we have to install a CEE incase a "future" electrical supply
may be needed to supply the detached structure.
