  • Marine construction activities e.g. building projects, jetty and concrete bridge construction
  • Development projects running adjacent to waterways
  • Dredging Projects
  • Piling operations
  • Marine excavation
  • Aquatic plant control
  • Algae control

Project Considerations

You can still create an effective floating turbidity curtain or 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.

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?

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.

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?

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.

Frequently Asked Questions

What is Silt Curtain?
Silt curtains are aquatic systems constructed from Geotextile. They feature floats that sit on top of the water surface and a skirt that sits perpendicular to the water surface. As soil contaminants such as silt approach the silt curtain skirt they are prevented from migrating past the barrier. This causes the suspended sediment and silt to drop to the bottom of the aquatic floor within the confines of the water column.
How does a silt curtain work?
Silt curtains provide a permeable barrier, trapping silt in place. The barrier is anchored in place to prevent movement due to wind, currents or tidal flow.
How to install silt curtain?
We recommend using an experienced operator to install your silt curtain. If unsure speak to us and we can advise you. In general, however, the steps can be broken down into the following:

Join the curtain sections, starting with the chain section at the bottom of the curtain.
Once assembled, tow into position
Anchor the silt curtain into place

How much do silt curtains cost?
This depends on your requirements. Silt curtain price is calculated based on the length of curtain required and other factors including tidal influence and wind conditions.
Can they be reused?
Silt curtains can be re-used in some circumstances. They must be cleaned before storage. Storage requirements may differ based on the specifics of your product. If unsure speak to us first.
