Marine & Waterways Protection Installation


Floating Silt Curtain Installation

Aussie Environmental understands the uniqueness of each project, the constraints and compliance requirements.  We are trained in erosion and sediment control best practice and have many years of practical experience.

Silt Curtains or Turbidity Curtains are floating marine barriers that prevent silt from spreading throughout waterways. Silt Curtains are used for dredging, excavation, piling operations, rock walling and other marine construction activities.

Our Silt Curtains come in 2 different classes:

  • Class 1 (non tidal - suitable for still waters, ponds & streams) available with 1m or 2m skirts
  • Class 2 (tidal - suitable for moving waters, tidal areas & seawalls) available in 1m and 2m skirts (in stock) and up to 6m skirts (custom made).


Floatation consists of high density closed cell, polyethylene foam. These floats are crumble and oil resistant, ensuring continued floatation. Depending on the scope of the project we would recommend use of the following flotations: 

100mm x 50mm floatation (Class 1, non tidal areas)
100mm x 100mm floatation (Class 2, for tidal areas)


All Aussie Environmental Silt Curtains are constructed using a 270gsm geotextile fabric, but can be customised to site and customer requirements. The depth of the silt curtain skirt is based on the information provided in the specifications and should take into account the fluctuation in tidal levels. As a rule the depth of the curtain should be sufficient to create an adequate silt barrier in the conditions, whilst leaving sufficient water beneath the curtain to allow the passage of marine life. We suggest a minimum gap of 500mm during low tide.

Bottom Ballast

Aussie Environmental Silt Curtains are held in position by a galvanised chain along the length of the curtain. This ballast is sewn into a chain pocket at the base of the curtain during the manufacturing process.

Strength Webbing 

Seat belt webbing will be installed along each section of the curtain. One on the top of the float, one directly below the float, while for large curtains one between the bottom ballast and skirt. The webbing will assist in supporting the tidal force placed on the silt fence fabric curtain.


Silt Curtains are connected using specially moulded aluminium connectors to attach the float section of the curtain. These connectors provide strength and durability in the water. For offshore conditions the option exists for heavy duty moulded connectors to add strength. A heavy duty marine zipper is utilised to connect the lengths of the skirt which allows for identical sections of curtain to be replaced if necessary. Bow shackles will be used to ensure the connection of the curtain’s ballast chains.

Anchor Points

Attachment points are present on all aluminium connectors via stainless steel eye nuts and furnished with a galvanised steel chain. These are attached with a bow shackle on one side of the skirt.

I ordered some Geofabric from them. Even with the delivery cost they were still cheaper than I could purchase it for around my area. Delivery would have been about 4-5 days so they took it upon themselves to use another company with delivery time cut in half. Very impressed with the professionalism and care taken to look after me. Thanks.

This is my second order of retaining pins.

I can order in a box of 500 which is less expensive than smaller amounts. The website is easy to use and find what I need.  But I’m impressed with communication from Aussie Environmental, I know once they’ve received my order, I then received a copy of invoice via email and TNT courier tracking is wonderful!!!!!

I have only brought Coir Peat from this place. The quality of this product is excellent, but the product was underweight  and does not expand as much as the product I buy from my local hydroponic shop. I would still buy  Coir Peat from this place if I lived in the area or was passing by. The price is cheap
