In Oklahoma, while the weather turns cold and bitter in the winter, it doesn’t often cause active construction sites to close for months at a time. Still, we deal with rain, snow and ice throughout the winter months. That not only can create construction delays, but also some real problems regarding erosion and sediment runoff. Here are three options for combating erosion control on construction sites during the winter.
- Mulch
Because it acts as a soil insulator, mulch can help soil to retain moisture and promote the growth of plants and grasses. In the winter, it’s primary use, however, is as a temporary soil stabilizer. In the proper application rates, mulch can keep soil in place, but doesn’t last long. Depending on the amount of precipitation and the grade of the slope it’s on, mulch will need to be replaced quite frequently. Still, it’s a cost effective solution for short-term work stoppages. Typically, straw or wood chips are used and it’s recommended that a 90-percent coverage is applied, which is equal to about 2 tons per acre.
- Erosion control blankets
Often the go-to erosion control solution, erosion control blankets are layered mats ideal for applications on steep slopes where other solutions won’t hold up. As with other erosion control solutions, blankets provide soil stability, but can also be used in combination with seed to promote vegetative growth. Choose from synthetic options, or the recommended bio-degradable erosion control blankets. The blankets are anchored into soil, which makes them a more acceptable long-term solution than mulch. They also perform better in preventing erosion in any application and require less maintenance.
- Hydromulch
Also referred to as hydraulic soil stabilizers, hydromulch is a spray-on erosion control solution that’s easy to apply. It’s sprayed out of a large hose and can be combined with seed so vegetation can grow and assist in keeping soil in place. Using seed is a good option for long-term erosion control, but for short stoppages, spraying hydromulch without seed is also effective. It’s better equipped to stand up to precipitation than mulch, but will still wear down after a few rain or snow storms and require re-application.
