Floating silt curtain, sediment curtain, silt boom and turbidity curtain are all common names given to floating curtains designed to contain and control silt migration in waterways and aquatic systems. As a result, they are commonly used during project construction such as dredging and excavation.
Trade Enviro specialise in product design, management, supply, deployment and installation of silt curtains to control silt migration at your project site.

Silt Curtain Design & Installation
We have experience with project demands including installation requirements that take into account flow rates. We also have a thorough understanding of the limitations and measures required to control releases and ensure project time frames and conditions are met. Silt curtain project requirements can be time-consuming. Trade Enviro can also offer a complete silt curtain product design service along with supply and install, Australia wide.
Speak to the Experts
Our range of silt curtains are suitable for long and short-term deployments. Our full range is completely scalable. Building construction demands, management timeframes and conditions contribute to the selection and deployment of your silt curtain. We offer specialised consultancy and support to assist with making the right choice for your requirements.

* Heavy Duty options available
Heavy Duty Sediment Curtains
Trade Enviro supplies HEAVY DUTY curtains for heavy duty applications. We offer a range of inexpensive sediment curtains designed for short-term use to full-scale long-term deployment projects. Ideally suited to waterways adjacent to construction sites, rock walls, mining, and industrial applications.
Our silt curtains can be used as an effective barrier in calm water environments such as aquatic ponds along with rivers, estuaries and open water conditions to control suspended solids and settle silt releases. Our curtains are built tough for Australian conditions with the highest grade construction materials available.

- Timeframe? How long do you need your curtain in the water?
- What’s the condition of the water? is it tidal?
- Will I need a directional type anchor system or an embedment style anchor system?
- How will a larger tide affect my curtains?
- How much buoyant force do I require for the most effective result?
- What ballast requirements do I have?
- What impact will I have on the safety of marine animals?
You can still create an effective curtain barrier and ensure a safe passage for marine animals to pass under the curtain. The principle of a silt curtain is to deflect the water towards the bottom of the sea floor taking suspended particles with it. Only a portion of water filtrates through the curtain textile.
Water follows the path of least resistance and therefore when the water passes under the curtain the suspended soil contaminants and silt sediment is closer to the sea floor promoting it to drop out of suspension and settle to the sea floor faster. Silt curtains primary design function is to promote the settlement of particles without disruption to aquatic systems nearby.
About Silt Curtains
Aquatic booms and barriers such as silt curtains are designed to control the movement of silt from activity in the marine environment; these products consist of a closed cell chamber and a skirt that sits beneath the surface of the water.
The skirt is specially weighted to sit perpendicular to the water column and is usually made of a geotextile mesh, woven or non-woven material.
Silt usually migrates within the first 2 meters of the water column from surface disruption. It’s important to control and settle the sediment so it has no impact on nearby aquatic systems.
Silt curtains are available with different length skirts depending on the application and different size skirts require different floatation and ballast.
Depending on the tidal influence, wind and conditions various anchoring techniques are available.
