Dang, culverts are expensive...installation suggestions?

[Shinesintx]

Finally biting the bullet and buying a 6'x 20' and 5'x 20' galvanized steel culvert. Delivered, it's gonna be 3k...so I'd like to make sure I install them properly. Any and all suggestions will be appreciated.

Make sure your pipes are big enough. You going to need permits?

County installed ours, for free. You might call and ask.

our county did the same for us they installed it and put several loads of crushed rock to cover it you are paying for the installation through your taxes

Five and six foot culverts don't sound like a driveway. Don't have a clue where you are putting these but you can screw it up if you don't backfill right. I've put many in, up to ten foot in diameter, and if they aren't compacted right below the " curve " they can collapse or wash out easily. Twenty feet is pretty short for that size of culverts too. You'd be lucky to get a 12' driving surface and it will get narrower as time goes on.

I own a 2 1/2 acre road that gets me to my property. On the west side is a farm with lots of runoff. On the east side is a creek. I need these culverts in two spots to let water pass under my road. The week before last, got 5 inches of water that destroyed both smaller culverts. Trying to go bigger.

12 foot of driving surface would be a dream.

I just texted my neighbor, he has an easement on my road and he splits the cost of repairs with me. Gonna have him make the calls. Hopefully my county does this.

The dirt road into my place is about a half mile. The first culvert closest to the road is probably 200 yards from the county road. If the culvert was next to the road, may need a permit....but don't think so, being that it's so far from the county road.

With a 5' culvert only 20' long considering 10 of driving surface that only leaves 5' on either side for a slope. That would be a 1:1 slope that would easily erode in certain conditions. What type of soil are you working with?

Can't see you needing permits well within your property, but I can't see the county working on your place either. If they did, they'd have to do it for everyone. They might put in driveway culverts coming off a county road, depends on the county, but not on your place. Is there running water in the creeks ? If so, that's another problem. May have to dam the creek temporarily to backfill. You probably need some help from a contractor.

Sandy loam. I'm thinking I may need to rethink what I'm doing.

I"m struggling with the same issue. 36" culvert coming under my fence with a live spring fed creek. Culvert is rusted out (I think). Every time it rains hard the dirt washes out around it. So bad I can't drive over it. Completely blocked from part of my property.

Lots of $$ to do it right.

My suggestion. Get two or three contractors out to look at it. Have them write you up a bid to install the culverts. Ask ALL OF THEM how they are going to compact the dirt under the curve, that is: the bottom half of the culvert. If that isn't compacted correctly, you can easily have a washout or crush the culvert with a heavy load (as noted above). You probably can get by with a foot to 18" of cover if only light traffic is crossing it. The heavier the traffic, the more cover you need. If the creek bed is soft, you may have to undercut it and backfill with better material, preferably heavy clay. Lots of factors impact cost on a project of this nature, you need someone to help you that has experience in the field. Good luck !
