[TowerTalk] concrete

[Doug Scribner]

Tom,

Base was poured in August 2012. I actually wrapped a blanket around the base and kept that damp. This was recommended by the concrete vendor.

It has been in for over a year and already gone through one New Hampshire winter with no issues.

  Doug:

  One thing you might do is what I was told when I put in my base back in 1993.  Lightly water the concrete base daily.  I mean lightly, no gushers,  etc. Just a sprinkle for a couple minutes.  This helps take out the heat from the curing concrete.   I mnust have worked because my 4x4x6 ft base is still in fine shape as when I put it in.

    My US Tower first advised 90 days, but the eventually relented and told me
    28.  I think I waited six to eight weeks; don't remember now.

    Remember, though, that none of us are structural engineers. You might want
    to check around to be sure.  But, I believe that's standard information and
    you should be able to google something up from a reputable source.
