Question for those that have been there, done that.....
I am almost ready to replant a 13.7m Nally tower. I am trying to sort out an issue that I came across with information in the computations book.
The original instructions call for a hole 381mm diameter, 3m deep. OK, fair enough, these are dated 1977. However, also included is an additional sheet dated 1983, which states 381mm diameter, 2.4m deep. We are not in a sandy soil area, fair bit of clay and shale down lower.
Question 1; Which hole depth is correct?
Question 2; Those that have been down this path previously, did you include a quantity of mesh or rebar in your concrete?
