How Deep & Wide?
I've got a 3" dia. x 20' long iron pipe I want to set in concrete to hold a security camera and motion detector light.
Just wondering how big the hole should be to keep things straight and stable. Thanks.

Re: How Deep & Wide?
How deep do you plan to place the pipe?
I would think that 2' diameter if you can get 4 or 5' deep would work. I recently bid a job to place a concrete footing for a commercial sign, (Jiffy Lube), it needed to be 7' deep and 3' Diameter. |

5 ft in the ground min, best guess without seeing soil conditions.

Re: How Deep & Wide?
The smaller light pole bases we installed on a job recently were 6' deep with a 3' diameter.

Re: How Deep & Wide?
We did a job last year with 10 foot high aluminum light poles. footings had to be 7 feet deep, 30 inches round with steel cages. Kind of crazy in my book but you gotta love those engineers.

Re: How Deep & Wide?
That might be due to traffic, or may be due to estimated wind loads on the poles.

Re: How Deep & Wide?
I just put together a proposal for installing a 15' tall street lamp and the recomended footing was 2'X4' for this area. There is alot of stone where it is going, thanks god for mini-ex's.

Re: How Deep & Wide?
Need to be buried 1/3 of the total size of the pole. Hole needs to be 9" dia.

Re: How Deep & Wide?
Anything more than five feet deep would probably be fine, but I'd probably make it anywhere from 6-7. Always better safe than sorry.

Re: How Deep & Wide?
Sclancy...sorry for the delay. I just got out of the hospital with an infected appendix.
I tried to pm you but it wouldn't let me on your end, or, I'm too tired to figure it out. 'Sup? Rob
