It probably depends somewhat as to soil conditions.
I've had, and seen, many clamps come loose in just a year or two and 
that includes quite a few installed by electricians on house electrical 
grounds.

We had to use a string of three rods to satisfy the code for our ground 
conditions.  A couple years later we went from an overhead feed to 
underground.  (concrete truck hooked the line on the way to pour the 
shop floor. )
I decided to check the grounds and all clamps could be lifted off the 
rods using only two fingers.  The electrician who put those on 
emphasized that they had to be tight and he was a lot bigger than me.

The soil here, in general, is damp and acetic.  The house electrical 
ground is is partial fill  which is mainly clay,(back fill is sand) but 
the moisture is still acetic.  We are right at the edge of a wooded area 
which is almost peat across the N and W sides of our 1 acre lot.  I 
assume this area was that way as well.

I've never had a CadWeld fail.
