RE: FLAG POLE FOUNDATIONS in CA

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Let me clarify "foundation"... I really need the correct approach for the 
pier design....the manufacturer's provide their own design which typically 
involves embedding the pole into a corrugated tube which is then filled with

sand. The corrugated tube is placed in approx. 3'-0"x12"dia of concrete 
(unreinforced?). I am concerned that this support may not be
sufficient...the 
numbers that I ran for the UBC criteria required a pier embedment of about
15 
feet!....
Thank you for the input...

There are two options:

1. Chemical/Epoxy Anchors: contact Hilti Mfg. at www.hilti.com 
2. J-hook Steel Rod (F1554 Gr.55) or Deformed J-bar (ASTM 615       Gr.65)
