Re: Found An Underground Stream While Digging A Garage Pad Today. What To Do?


be my guess, it's not ''the'' water table, or stream. be my guess you have a sand lens that is full.

how i'd deal with that locally would be strip off all organic material...have vac ex truck come in, suck me down a ten inch slotted pvc casing on each building corner make holes 18-24 inches in diameter, backfill with CLEAN pea rock..throw sump pump with float in each one...let pumps work for several weeks. you'll be surprised how good it firms up.

you start bringing in rock, busted concrete and pushing it down into mud without remediating the problem, you're going to have a yard full of owl sheet and never build on it.

Re: Found An Underground Stream While Digging A Garage Pad Today. What To Do?


Thanks for all the replies guys. Sound like the next step is to convince HO to bring an engineer in and get it done right. I would really love to get in there and fix it up at least temporarily so it doesn't look like hell...but I'm afraid I'm just asking for a buried machine.

HO says there used to be a real live stream somewhere in there but developers covered it up years and years ago. I was amazed to see clear water flowing out of the dirt about 18" deep, but it wasn't enough to be a broken water line. We'll see what kind of circus this 1-day job turns into.

I'll be sure to pass this on to the HO. He should just be happy we're keeping it under 10 million haha!

Re: Found An Underground Stream While Digging A Garage Pad Today. What To Do?


So, customer informed me that his new garage is going to be pole built. If that's the case, as long as they get the footings below the water there should be no issues.

I'm thinking I can go back with a mini-x to finish the grading. Then I can build a gravel pad on top and isolate it with geo-textile fabric so they've got some stability for parking.

Anybody got any better ideas?

Well that's always an idea too, but he's been a good customer to me.


He'd already paid this pole garage company a deposit to build by the time I met him for the first job. He wanted to build a new garage on the cheap, but the price didn't include site prep....so here we are!

Great idea! Maybe I can up-sell the job with some nice stain and sealer so it really lasts.
