TerraStop Silt Curtains

Product Code: 30-SICR15

TerraStop Silt Curtains, also known as Sediment Curtains, Floatation Curtains or Turbidity Curtains are designed to control sediment, algae or debris movement in waterways.

Deployed during civil works in or next to waterways to control silt and sediment into the waterway.

The purpose of silt curtains is to control silt and sediment in Water facilitate the ease of localised settling. Designed to create a controlled area of containment so that settling can occur.

Description

The curtain is weighted down with a chain ballast, so it sits vertically in the water and is usually made of a woven or non-woven geotextile. It’s important to contain silt and debris so it has no impact on nearby aquatic systems.

Silt curtains also known as turbidity curtains are floating impermeable barriers used to trap sediment in bodies of water during civil works. Weighted at the bottom of the curtain, ensuring sediment does not flow under the curtain.

Silt Curtain Types

Silt curtains are available in Type 1, 2, 3 and Engineered Curtains with different length curtains depending on the application. Various sizes, flotation and ballast are also dependant on the intended use of the Silt Curtain. Depending on the tidal influence and wind conditions, various anchoring techniques are available.

Type 1 Silt Curtains

designed to prevent and contain silt and debris contamination of waterways from man-made or natural erosion. Australian-made and cost-effective, they are suitable for use in calm sheltered and inland waters – lakes, rivers and estuaries.

Type 2 Silt Curtains

designed to prevent and contain silt and debris contamination of waterways from man-made or natural erosion. Australian-made and cost-effective, they are suitable for use in calm to moderate flows and tidal water – lakes, rivers, estuaries and harbours.

Type 3 Silt Curtains

esigned to prevent and contain silt and debris contamination of waterways from man-made or natural erosion. Australian-made and cost-effective, they are suitable for use in moderate to high flows and tidal water – lakes, rivers, harbours, open waters and ocean.

Deployment

  • Install mooring points after determining location of shore mooring.
  • Appropriate moorings such as deadman anchors, posts or precast blocks can be used depending on the ultimate curtain loading.
  • Flotation curtain comes fully assembled with floats and ballast ready for launching.
  • Unfold and place Flotation Curtain Panel near deployment or suitable flat area.
  • Completed Flotation Curtain has Float Pocket, Skirt and Ballast Pocket concertinaed together and secured with tie rope or cables. This provide least resistance during deployment.
  • Deploy curtain and secure at pre determined anchor and mooring points.
  • Cut tie cables or ropes to allow the skirt and ballast pocket to sink.
  • Secure curtain ends utilising the top webbing and continuous ballast chain.
