How to Master Dirt Erosion Control on Challenging Slopes

​Hillside erosion and erosion control on slopes can be a formidable challenge for any company. But, with the right approach and dirt erosion control, it's entirely manageable. 

How can you protect your hillside project with the right dirt erosion control technique?

Controlling erosion requires evaluating and understanding the unique characteristics of each landscape. You can tailor your dirt erosion control methods to the specific soil and slope of your project. Here are some essential tips to help protect your next hillside project.

1. Get to Know Your Hillside

Before selecting a slope stabilization solution, you'll need to deeply understand the makeup of the terrain you're working with. There are two areas specifically that are necessary to understand: the incline and the soil composition.

• Measure the Hillside Incline: A slope's gradient isn't just a number—it's a major factor in determining your dirt erosion control strategy. For example, if your slope is less than 33%, mulch might be an excellent solution for erosion protection. Mulch can secure the soil and prevent topsoil degradation. However, for steeper inclines, which are harder to access regularly, you may need a more permanent solution, like retaining walls or geogrids.
• Investigate the Soil Composition: Soil composition and depth are important factors to consider. If your topsoil is thin and primarily lies over rock, stabilization might be a bit tricky. While sandy soils have loose particles and are highly prone to erosion. Determine what type of soil is on your slope before selecting a dirt erosion control method.

2. Drainage and Water Interaction

How quickly does water drain off of your slope? Soil that drains too quickly can lead to erosion in the root zone of plants. On the other hand, soil that retains too much moisture may shift and slide due to added weight and pressure. Take time to evaluate how water will interact with your hillside terrain and the surrounding vegetation.

3. Investigate Problematic Landscape Signs

There are a few easy-to-spot signs of trouble on a slope. Some are obvious, while others require you to look more closely at the soil. Here are some signs that your hillside has poor soil stabilization and needs your immediate attention:

• Cracks: Take note of any large cracks in the ground or nearby structures. These can signal structural shifts caused by erosion.
• Bald Spots: If you see areas where there is little to no vegetation, that can also be a sign of erosion. Without plant roots holding the soil in place, it's likely that water and wind have carried away topsoil.
• Rills and Gullies: These narrow channels are formed by runoff from rain or irrigation. The presence of rills and gullies indicates there is a significant erosion problem.

4. Apply Dirt Erosion Control Techniques

There are various range of solutions to consider when it comes to dirt erosion control. Some common options include:

• Mulch: Mulching is a great option for gentle slopes with low rainfall. Mulch can hold topsoil in place, even without plant roots.
• Retaining Walls: Retaining walls are sturdy structures that can combat severe erosion on steep or large slopes.
• Polymer Soil Stabilizer: Polymer-based soil stabilizers are a cost-effective solution for controlling erosion on slopes. They work by binding soil particles to create a more stable surface and prevent runoff.
• Geogrids: Geogrids are synthetic materials that provide structural support and reinforcement to the soil, preventing it from shifting or sliding down the slope.

Ultimately, whatever erosion control method you choose, put a process in place that includes consistent checks and maintenance.
