Minot, North Dakota, is one of the most populous cities in the northern half of the state. Therefore it is also one of the best places from which we can get an idea for what weather up north is like during any given Winter. Minot averages a high of 23 with a low of 7 during the month of December. You’ve probably heard about “where the wind comes sweeping down the plain.” This lyrics refers to Oklahoma, but the winds really howl down the plains of North Dakota. Wind chills can reach a chilling 45 below zero.

Of course, no one is working on the pipeline when it reaches these conditions. But it gives you an idea what kind of atmosphere a pipeline needs to stand up to.

It would also be highly irresponsible for a pipeline contractor to leave a drain tile repair uncovered until the crews return during the Spring. But, theoretically, what if they did? What if they bridged a broken drain tile, and left that bridge unburied, at the mercy of the prairie winds?

First of all, it depends on what kind of bridge was being used. Traditionally, pipeline companies have used sandbag bridges to hold up repaired drain tile. The problem is bridges that are built from up to 150 bags of sand, and assembled by hand, have a tendency to fall over. The weather doesn’t even matter; more often than not, just dumping to topsoil back on pipeline is enough to knock the sandbag bridge out of place.

What happens when a drain tile repair bridge falls? The drain tile breaks, and the process starts all over.



Mad Dog Foam Bridges were developed to combat this collapsing problem. First, it’s only one piece, so proper installation is much simpler than hundreds of sandbags. Second, our Foam Bridges are designed to fit snugly on top of the pipeline, so they won’t slide—either above or below ground.

But just how snugly do they fit?

That was a question we wanted to answer when we left a Mad Dog Foam Bridge on top of a pipeline segment over the Winter, to reveal the results during the Farm Science Review the following Spring. Not only would our bridge need to stand up to the wind, it would also need to deal with precipitation.

It stood up to the test (and you can tell, because we wouldn’t be publishing this blog post if it hadn’t). Several inches of snow, and gusts up to 40 mph couldn’t shake our bridge.

Many pipeline operators and contractors lack confidence in their drain tile repairs because wobbly bridges collapse when buried. This costs them time, and it definitely costs them cash.

Mad Dog Foam Bridges can stand up to the worst that Winter can throw at them. Being buried? No problem.

Be confident with your drain tile repairs. Go with Mad Dog Foam Bridges.
