Silt Curtain With Woven
Polypropylene Geotextile Fabric
Question regarding an permeable silt curtain with geotextile fabric. My project requires a silt curtain with woven polypropylene geotextile fabric, EOS US Standard sieve, total length around 300 feet.
The turbidity curtain is required for a boat ramp in ponds. The average depth of both ponds is seven feet, the maximum depth around 13 feet.
What curtain size and style do you suggest?
Answer:
Thank you for contacting us! Choosing an permeable silt curtain with geotextile fabric that will best work in your location depends on a lot of different factors.
In general, in order to choose the best silt curtain style for you area, we would need to know if there is a water velocity in your area and/or if there are any waves or tides silt curtains are typically made in three different types. We work with customers to choose between these types by analyzing the project requirements and water conditions.
Impermeable and Permeable
Silt Curtains
Silt curtains are typically used for containment of materials and are not usually constructed from a filtering fabric, such as a woven geotextile. You will usually see more robust options such as PVC being used for a boom so that materials can stay completely containment.
However, we do offer a permeable silt curtain with geotextile fabric model that includes the use of filtering geotextiles. These geotextiles will be added to skirts of a barrier as part of a specially modeled permeable barrier. While this silt curtain would feature large geotextile panels, the outer component would still be made from a PVC type fabric.
Sizing and Depths
Depths for these turbidity curtains, including silt curtains with geotextile fabric added, are usually chosen based on the water depth in your area. Since you have mentioned that your area has multiple depths, you might consider using sections of barrier with varying lengths to adapt to this changing size. You will usually want you barrier to sit approximately one foot from the floor of your water location.
Standard section sizes will be made in either 50 or 100 feet. These sections can then be joined together to meet your required length of 300 feet.
