[TowerTalk] best way to seal concrete with cut off tower section

[mike stokes]

I am in the planning stages of replacing 95' of Rohn 25 with 100' of Rohn
45.  The 25 has the bottom section concreted in.  I plan on drilling and
epoxying a pier pin for the Rohn 45.  When I cut it off the 25, the holes
in the legs will be exposed.  What is the best method to seal the leg holes
to ensure they don't get water in them and freeze ?

Thanks in advance.
