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.

It’s good to see Frog getting involved with GT at the earliest stages of the project to help with planning out water management in advance of needing it.

“Frog Environmental were knowledgeable, helping to establish a workable, cost-effective and low maintenance solution for site approved by the regulator. They really understood the water management issues we had on site and worked with us to develop a solution which works, as well as engaging with our operatives to ensure that they could effectively manage the system.

We are delighted to have found a solution that prevents pollution and protects the environment, and ultimately allows us to continue with construction.”

The surface water system drainage feature utilised innovative solutions from Frog Environmental.

A rain-ready strategy was implemented, which enabled the development of a robust management system capable of effectively managing fluctuations in weather conditions year-round.

This provided a timely, sustainable and cost saving solution for our client.

They (Frog Environmental) were efficient in providing advice and the most appropriate product for our project. The team responded promptly to ensure the Bubble Curtain was delivered to the site on schedule.

It has worked well and has been great on site. We are demobilising this week, and the bubble curtain is already in store at our next site for reuse!

The Kex Gill road realignment scheme is a challenging project with multiple environmental risks including management of silt and water quality of the surrounding environment given the locality of designated sites.

Frog Environmental are providing us with extensive technical support, including the design, supply and install of their silt control products on site to ensure the project minimises risks to the watercourses in the project vicinity and prevents impact on highly sensitive aquatic species.

It’s great to be working with them and we’re delighted with the success of the whole project.
