Aquatic silt curtain, turbidity curtain, and containment booms are all common names given to floating curtains designed to contain and control silt and sediment plume migration from aquatic systems during project construction phases.
Silt Curtain Installation
Trade Enviro specialise in the design, supply and/or installation of silt curtains to control silt migration at your project site to suit your demands.
We are conversant with typical project demands including installation requirements that take into account flow rates and limitations and measures required to control releases and ensure project time frames and conditions are the first priority. Silt curtain requirements can be time consumable and Trade Enviro can also offer a complete and competitive service to design supply and implement your silt curtains across your projects anywhere in Australia.
Our range of silt curtains is suitable for long and short-term deployments with a full range that’s completely scalable. Project demands, timeframes and conditions contribute to the selection of your silt curtain. We offer specialized consultancy and support to assist with making the right choice for your requirements.

* Heavy Duty options available
Heavy Duty Silt Curtains
We supply HEAVY DUTY curtains for heavy duty applications. We offer a range of inexpensive silt curtains designed for short-term use to full-scale long-term deployment projects. Ideally suited to construction sites, mining, and industrial applications.
Our silt curtains can be used as an effective silt 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 materials available.
Curtain management need not be expensive but it is if you have to do it twice

- 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 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 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 is to promote the settlement of particles without a large amount of 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; they consist of a floating 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, 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.
