What Material Should You Avoid When Using a Diversion Fence?

Mastering Maryland’s Erosion and Sediment Control: Your Guide to Diversion Fences

When you think about tackling erosion, what often comes to mind? Maybe it’s thick green grass on a hillside or those heavy tarps you see at construction sites. But here's the real deal: to control erosion effectively, one of the heavy hitters in the playbook is the diversion fence. This unassuming structure plays a pivotal role in both construction projects and environmental management. Let’s unpack the components that make a diversion fence so effective and clarify what materials you should (and shouldn’t!) pair with it.

What’s the Buzz about Diversion Fences?

Let’s start with the basics. A diversion fence is designed to redirect water flow during a rain event. Think of it as a guide, telling water where to go instead of allowing it to pour off the side of a hill and carry precious soil with it. You know what they say about water—it travels wherever it can. So, keeping it away from sensitive areas is crucial, especially in places prone to erosion.

To ensure a diversion fence works its magic, the materials used are absolutely critical. Here’s where it gets interesting!

Material Showdown: What Works with a Diversion Fence?

You might be wondering, “What kind of materials can I use with a diversion fence?” Well, let’s put this into perspective. The top contenders often include various types of geotextiles. But before we get all technical, let’s also clarify what’s off the table.

Here's a little quiz for you: Which of the following materials would NOT be used with a diversion fence?

• A. Woven slit film geotextile

• B. Woven monofilament geotextile

• C. Plastic sheeting

• D. Nonwoven geotextile

If you said C. Plastic sheeting, you're absolutely right!

Why Plastic Sheeting Just Doesn’t Cut It

Now, you might be scratching your head at this point. Why is plastic sheeting a no-go? It seems like such a versatile and durable option, right? But here’s the kicker: plastic sheeting doesn’t allow water to flow through. Instead of filtering or managing the water, it tends to trap it. This can lead to water pooling, which creates increased hydraulic pressure. Imagine trying to block a leak by stuffing a cloth into a pipe—sooner or later, the pressure's gonna blow!

Geotextiles, whether woven or nonwoven, are designed for permeability. In simple terms, they allow water to pass through while filtering sediments, serving a much larger purpose than simply acting as a barrier.

The Power of Geotextiles: Understanding Their Role

Let’s break down the geotextile options that work well with diversion fences:

1. Woven Slit Film Geotextile: This type is excellent for stabilizing soil and filtering out sediment. Its structure allows for good drainage, ensuring that while water passes through, it doesn’t carry along unwanted soil. Think of it as a shield, protecting fragile areas from erosion.

2. Woven Monofilament Geotextile: Similar to its slit film counterpart, this geotextile also provides filtration and drainage. The difference lies in its structure, making it versatile for various applications. So, whether you’re building a road or setting up a park, this option has your back!

3. Nonwoven Geotextile: Here’s where things get a bit more intricate. Nonwoven geotextiles are known for their drainage capabilities while enhancing soil stability. They’re particularly handy in managing sub-surface water flow. Picture a sponge—these materials absorb and channel, preventing that dreaded erosion.

How These Materials Make a Difference

By utilizing the right materials, we improve the efficiency of our diversion fences. They prevent sediment-laden runoff—a fancy way of saying they stop dirty water from entering delicate ecosystems. This not only protects flora and fauna but also upholds state and national environmental standards.

Have you ever walked through a construction site after rain? It's often a muddy mess, right? But diverting water and using proper materials can turn a potential disaster into a manageable situation. Plus, thinking long-term about erosion control helps protect our beautiful Maryland landscapes for generations to come!

Wrapping It Up: The Road Ahead

The importance of selecting the right materials cannot be overstated—especially when they can mean the difference between a sustainable project and one that leaves a trail of environmental damage.

So, next time you find yourself looking at a diversion fence or planning a construction project, remember the components that make all the difference. In Maryland, where the beauty of the natural landscape is a key part of our identity, it’s our responsibility to ensure that erosion control isn't just an afterthought, but a core consideration.

Hope this sheds some light on the fascinating, sometimes overlooked world of erosion and sediment control. It may seem like a technical subject, but at its heart, it's about protecting the land we love. Keep your eyes peeled for opportunities to implement best practices in your own projects!
