The bearing must be on undisturbed soil, which would be at the level of the bottom of the tank.

You've got a little digging to do Monday.

I'm surprised the "sonar" did not detect the tank before you started.

Do you have or know the soil compaction numbers. In our area you can if the soil is at 3300 psi compaction rate and is verified by a soil test report.

Are you building with a cantilever and can you move the pier over?

Also consider the posibility of eventual damage being blamed on you down the road if there is a problem with the tank!

No i dont know the soil compaction numbers. It does have a 2' cantilever allready and im allready pushing it back about 4" no big deal though. Ill figure it out, ill put a steel beam in there and just shoot right over it. lol The building inspector will tell me what to do hahaha

is the deck in the way to pull the lid for pumping?what happens if the tank needs to be replaced?

SLSTech · 04-11-2009, 08:33 AM

Down here we are not allowed to build anything within 5 feet of the tank - Even if it was allowed, I definitely wouldn't want to be right up against it

What size joist are you using, a 4' cantilever is a little excessive for standard framing.

ronm1974 · 04-11-2009, 08:37 AM

The deck will over hang the tank by 2' and no its not covering the lid. I just have to find out if there is anything about how close anything can go near it. I cant find anything in the code book.

ronm1974 · 04-11-2009, 08:38 AM

12' x 28' deck with 2 x 10 joists with an overhang of 2' feet.

My bad, I thought you said a 4' overhang. Get the approval from the village in writing!

ronm1974 · 04-11-2009, 08:49 AM

i will get it in writing for sure but what you did make me think of was what about a 3' overhang. then that way im a foot away from the tank and i should be ok. except ill be re-digging my holes. oh well it was easy digging.

I'm just checking! Geesh! I didn't know if you were putting in a deck or checking for fish in the septic tank

Does the pier in question support a beam end?
What is the current cantilever of the beam, not the joists?
What is the size of the beam?

Can you draw a diagram of location of beam,piers and septic tank...or give us a complete description textually?

Off the top of my head, I don't know where you'd go looking for a code specific reference but I'd stay 5' away, like SLS spoke of. You are probably going down 4' or so, you'd want at least that much space laterally from any disturbed soil.

You might be able to work around the tank by dropping in 2 piers and an angled beam but I'm just guessing until you can give us a description of the layout.

P.S. - I would caution you about following whatever advice 'deck king' had for you. He's not proven himself to be anything more than a nuisance who runs hard and long w/ erroneous facts.

Ya i guess i can see how you could make that assumption.

ronm1974 · 04-11-2009, 09:02 AM

12'x27' 6" deck 2x10 joist with an overhang of 2'. footing currently at 6'10"1/2. the footing in question is the center footing with me hitting the short side of the tank. the tank is at an angle.

Yeah...me too. You must be new to the game so I'll give you some slack.

Yea, go ahead and listen to " big mac for brains" and all your deck will support is the crap that so effortlessly flows from the special sauce soaked mentality.

Look at Mac's site.
Read through his threads.

How do you keep talking with
