Erosion is a common problem on construction sites and extensive agricultural projects, and there are numerous ways to control erosion on a large scale. Silt bags have been proven to be an effective way to control erosion on construction sites. This guide will explain how silt bags are used for erosion control and give you a few tips for using silt bags yourself.
What Are Silt Bags?
Silt bags are dewatering products manufactured from geotextile fabrics. Dewatering is the process of removing water from a construction area with water pumps. If an area was flooded in the past, it may be necessary to pump water away from the site before beginning construction or excavation. By controlling the movement of sediment, silt bags help construction sites comply with stringent stormwater regulations.
Silt bags filter sediment and other materials from water. When you utilize silt bags, water flows through the bags and sediment is trapped inside.
Silt bags are used to filter water and can be used at construction sites, wastewater treatment plants, and any job site where sediment needs to be controlled. It’s necessary to mitigate erosion around construction sites in order to minimize the amount of sediment that is carried into lakes, rivers, and streams.
Sediment can carry pollutants that are detrimental to wildlife, so it’s important to manage the movement of sediment when possible. Using silt bags at construction sites will help protect nearby wildlife, bodies of water, and natural resources.
You can use coir mats, logs, or netting in conjunction with silt bags at construction sites. Coconut coir fibers have an unmatched ability to retain and absorb water. After the silt bag filters the sediment from the water, coir mats or logs will absorb the water for the surrounding vegetation. In this way, sediment-free water is able to be absorbed into the soil or go down a storm drain.
In addition, the coir mats, logs, and nettings secure the soil in place, preventing the filtered water from washing away the existing soil. Coir products are eco-friendly and biodegradable and provide essential nutrients to the soil as they decompose. They are wholly organic and leave behind no waste products.
Tips for Using Silt Bags
When you want to use silt bags for erosion control, you should first assess the area and see how you can protect the soil and surrounding vegetation. To prevent further erosion, you should support and stabilize the area.
Instead of throwing away the contents of the silt bag, you can put the silt and sediment back on the area for stabilization and support as long as they don’t contain pollutants or hazardous materials. Check the silt bags frequently for clogs or other impairments and replace the bag if needed.
If it’s necessary to pump water away from your construction site, it’s a good idea to use silt bags to control erosion and sediment movement. Using silt bags for erosion control is good for the environment and allows construction to take place without harming the existing vegetation or soil.
