Silt Sack - Sediment Trap
Silt Sack
High flow sediment trap for sewer inlets is made from a high-strength UV stabilized polypropylene, and can be filled with a range of mediums including coarse sand, gravel, or wood chips. Erosion Control Silt Sack can reduce sedimentation into combination curb and grate inlets. It is an important part of a comprehensive best management practice approach for site sediment control.
Silt sack can trap the silt but allows water to pass into the sewer. It can be used as a primary or secondary sediment control device to prevent failure of the drainage system due to clogging with silt or sedimentation. Maintenance of the silt sack on a regular basis will ensure that the sack functions properly.

Key Benefits of Silt Sacks
Silt sacks provide a simple, effective solution for storm drain inlet protection on construction sites and other high-risk areas. Installed directly in curb or grate inlets, these temporary catch basin filters capture debris from stormwater before it enters the drainage system, helping keep sediment, trash, and other pollutants out of local waterways.
Constructed from high-strength geotextile fabric, silt sacks are designed to withstand heavy flows while maintaining filtration efficiency. They’re lightweight, easy to install, and remove the need for more complex or permanent sediment control systems during short-term projects. When maintained regularly, they offer dependable protection and help meet environmental compliance standards.
Common Applications
Silt sacks are commonly used across a wide range of construction and infrastructure projects, including:
- Roadwork and paving jobs
- Utility trenching and excavation
- Site prep and grading activities
- Urban redevelopment and stormwater retrofits
- Any location where temporary storm drain protection is required
Whether you're managing a single job site or multiple locations, silt sacks offer a low-cost, high-impact way to reduce sediment runoff and protect your stormwater infrastructure.
