Managing Sediment Run-Off
Silt Fence
Silt Fence is designed as a temporary barrier to control the movement of suspended sediment and soil during groundwork.

Silt Fence captures sediment and allows water to infiltrate and percolate into the ground, preventing silt from being carried to ditches and streams where it can negatively impact aquatic life.
It can play an important role in managing construction related pollution incidents by forming a site perimeter barrier, intercepting runoff from slopes and protecting drains.
Silt Fence is quick and simple to deploy and provides a key intervention for the effective management of surface water on construction sites, especially when used in combination with other sediment control devices.
They are a simple, low-cost option for managing sediment run-off on construction sites. When installed correctly and maintained regularly, these fences can be effective at intercepting and slowing silty water, allowing heavier particles to settle out.
Choosing the right tool for the job is essential. Silt Fence remains a proven solution in the right conditions, but they work best when used as part of a wider silt control strategy tailored to the site.
Silt Fence is commonly used for:
- Site perimeter protection
- Overland flow interception
- Drain and surface water protection
- Surface water management plan intervention
- Reducing catchment flood risk
- Reducing pollution incidents offsite
Key Benefits
Frog Environmental’s reliable Silt Fence solution:
Quick to install
A simple, low-cost barrier that can be set up rapidly on land, providing immediate control of silty run-off where ground conditions are suitable.
Effective turbidity control
Proven in the field, Silt Fence slows the flow and captures suspended solids, reducing turbidity and protecting nearby watercourses.
Durable, reusable and recyclable
Manufactured from robust materials, our silt fence withstands tough site conditions and can often be reused across multiple projects.
Part of a wider solution
Best used as part of a site-specific silt management plan, Silt Fence performs well on land. It is not designed for use in ditches or in water, we can recommend other solutions which are more effective.
Rapid response & low carbon delivery
Our team respond quickly to both planned and urgent site needs, offering fast turnaround and carbon-neutral delivery.
