It was one of those days... I was installing a drain for my metal building's gutters - and as I was covering it up, I wondered if the 6" corrugated drain line I put under the driveway was going to collapse in the near future. (Kind of like, hmmmm, had I thought of that ealier I would have used PVC pipe.)

The good news is it is burried a minimum of 36" below the driveway, which should make a big difference. Next spring, I'll be running another drain line under the driveway (in PVC!), so if I determine I should replace the corrugated, then I'll re-route at that time. Anyone know for sure what you can and can't get away with?

On a side note - as I think I read earlier on this board, a 9" bucket is worthless unless your soil condidtion is perfect... After begginning the trench and shaking the bucket to get the soil out - to no avail - I switched to my 18" bucket, and the trenching went 3x faster.

There is a formula for what you are or want to do, but to be safe I'd use the Schedule 80 pipe. That stuff is tough! For added protection and easier installation just sleeve the corrugated pipe with a larger, stronger PVC. I can drive my 8,000 lb. skid steer over it and barely gives. In fact I used it as rollers to move a 1500lb. shed to a guy's backyard.

The biggest contributor to corrugated pipe collapsing is A rough-bottomed trench or backfill that is chunky rather than loose or pea stone which tends to extert equal pressure around the pipe instead of into it which casues failure. I've seen a lot of basement footer drain pipe that collapsed because the installer stood on it while backfilling (creasing it) or a chuck of dirt fell on it then soft material was backfilled around it (punctured it). If your driveway is higher or at the same level as the doorway you might want to install a trough- or french-drain. That way water can't get into the barn through the doorway, and, if washing the floor through the doorway it will be caught by the drain instead of the driveway. Shoot, you could install a trough- or french-drain all around the barn. The trough is usually a sectional, plastic composite, cast aluminum or steel. I bought a plastic one at Home Depot for a commercial application. A real french-drain (where I'm from) is usually a trench filled with gravel. ....

Thanks EW, it was during the gentle backfilling that I realized I most likely made a mistake... As far as not getting water in the barn through the doorway, check out my pics 17 and 18. The slow point for water drainage is a couple of large culverts under the road. If we get 4"/more of rain, and the rate is more than 1.5" per hour, the water will flow over the road. Well, they raised the road 7 freaking inches when they repaved it a couple of years ago. I had set up a berm around my shop as a result but there were a couple of spots that had settled and were a couple of inches too low. (I had them marked and just hadn't gotten around to fixing them, should-a, could-a, would-a.)

Anyway, getting the gutters to drain directly into the creek is the first of many steps in my flood prevention plans.

If you have gutters and downspouts then it's a natural to bring them underground and connect them to the perimeter drain, rather than let them run on the ground and seek a drain. ....

Even if he has freezing temps?I think he should have a way to disconnect his drain/gutters from an underground drain system in the winter. I may not be following this conversation correctly though? ....

I've done many a home putting the downspouts underground. The key is not having an obstructed water passage/drainage. And if it is freezing temps, what is going to flow anyway? ....

What you have to watch for in northern climates is that the vertical portions of the drain extend to at least 4' below grade to prevent freezing.

On a warm'ish sunny day the sun's heat can melt a lot of snow off a roof, if that has to go through frozen drain lines it will build ice slowly until it chokes the drain completely.

You would also have to be cautious about running a line horizontally beneath a driveway or other area that is cleared of snow. Snow is an insulant and keeps frost from penetrating as deep. The frost will go MUCH deeper beneath a driveway than it will the snow-covered lawn next to it. This can result in heaving in the driveway much the way a tree root does.

Best of luck. ....

I have used 4 or 6 inch of the drain pipe under a house drive way for a few years with no problem. It was buried no more than 1 foot. Now, there is no heavy equipment or freeze problem either.

Our DOT is using double wall corrugated drain line for driveways here with it being buried from about less than 1 foot to a few feet. There are from about 18 inches to 30 inches in diameter and they seem to hold up very well. Understand different class of pipe here.

If you don't crush it installing it such as has been covered earlier I think you will be fine unless you have some kind of vibrating load moving slowly or sitting on it.

At same time pipe very much like that is used for field lines in septic systems and not buried that deep with different loads over them at least for grass cutting. ....

Unless I can be convinced otherwise, I will most likely re-route the under the driveway portion in the spring when I run another drain line under the driveway. I have a 2 yard container that gets emptied by the 40,000 lb garbage truck, so it does see some heavy traffic on occasions.

The same driveway does have a 12" heavy wall plastic culvert (installed prior to my owning the propery) and it's held up, but like kthompson said - 'different class of pipe here'.

I've got pretty good slope all the way, so I'm not concerned about the freezing of the line. The creek it flows into is never high enough (during winter) to back feed the system.

Speaking of back flow, I found a really cool checkvalve (see web link). The make them from 2" to 120" in diameter. I priced out the ones in the 4 to 12 inch range, but they're pretty pricey at $400- $1300 for that range. ....
