Turf Reinforcement Mats (TRM), on the other hand, are permanent solutions made of synthetic materials that provide long-term soil stabilization in high-flow water areas or steep slopes. TRMs reinforce vegetation, while ECBs support initial growth and prevent early-stage erosion.
  • Can I use an Erosion Control Blanket in winter or freezing conditions?
    Yes, Erosion Control Blankets can be installed in winter, but they may take longer to establish vegetation. Some blankets provide insulation, helping protect seeds until spring. If vegetation growth isn’t possible due to freezing temperatures, blankets will still help stabilize the soil until conditions improve.
  • How do I choose the right Erosion Control Blanket for my project?
    Selecting the right Erosion Control Blanket depends on factors like slope steepness, soil type, expected rainfall, and how long you need erosion control. Straw blankets work well for short-term use, while coconut or excelsior blankets provide longer protection. For extreme conditions, reinforced blankets or TRMs may be necessary.
  • Do Erosion Control Blankets prevent weed growth?
    While Erosion Control Blankets help suppress weeds by covering the soil, they do not act as a full weed barrier. Some blankets are designed with a denser weave to reduce weed growth, but additional measures like herbicide application or weed-resistant seed mixes may be needed.
  • Can I seed before or after installing an Erosion Control Blanket?
    Seeding should be done before installing an Erosion Control Blanket to ensure good seed-to-soil contact and proper germination. If adding seed afterward, lightly rake or punch holes through the blanket to encourage growth.
  • Do Erosion Control Blankets work in high-wind areas?
    Yes, but in high-wind environments, extra staples or stakes should be used to secure the blanket. Overlapping sections should be carefully anchored, and a heavier-duty blanket material, like excelsior or coconut, may be more effective.
  • Are Erosion Control Blankets fire-resistant?
    Most biodegradable blankets, like straw or coconut fiber, are not fire-resistant and can burn if exposed to open flames. However, some synthetic blankets and TRMs have fire-resistant properties. Always check product specifications if fire safety is a concern.
  • Can I drive over an Erosion Control Blanket?
    Driving over an Erosion Control Blanket is not recommended, as it can shift, damage the material, and affect seed growth. If temporary access is needed, reinforced options or protective mats should be placed over the area.

  • What are the max water conditions for each curtain type?
    Type 1: 0 fps, still water and calm areas Type 2: 1 knot, moderate wind and waves under 2' Type 3: 1.5 knots, moderate winds and waves under 2
  • What sizes do the Turbidity Curtains come in?
    Depths: The depth varies depending on the body of water depth and condition in your location. The most common is 5' deep. However, BMP Supplies manufactures anything from 2.5' - 30' curtains. ​ Lengths: Our curtains are sold by individual sections. The standard sections length is 50'.
  • How deep of Turbidity Curtain do I need?
    Depth for the turbidity curtain is chosen based on the depth of the water in your location. As a standard rule of thumb the depth of skirt should extend down until it is about one 1' from the floor. This allows the curtain to provide maximum containment without the bottom of the skirt getting bogged down with settled silt/turbidity/sediment.
  • What type of Turbidity Curtain should I use?
    Choosing the right silt curtain for your location is often dependent on different site factors and conditions. The standard classifications for our turbidity curtains are as follows: Type 1: Calm Water Type 2: Medium Water Conditions Type 3: Fast Water Conditions ​ You can compare all of our various curtains HERE
  • What is the difference between permeable and non-permeable turbidity curtains?
    1. What is the difference between permeable and non-permeable turbidity curtains? Permeable curtains allow water to pass through while trapping sediment, reducing pressure in high-current areas. Non-permeable curtains create a solid barrier, fully containing sediment and preventing dispersion. 2. When should I use a permeable vs. non-permeable turbidity curtain? Use permeable curtains in high-flow areas to prevent water buildup while controlling sediment. Use non-permeable curtains in calm waters for maximum containment, such as dredging or shoreline work. What materials are used for each type? Permeable curtains: Made from geotextile fabric, which filters sediment while allowing water flow. Non-permeable curtains: Made from PVC fabric, forming a watertight barrier for complete sediment control. 3. How do I choose the right option? Consider water flow, regulations, and sediment type. High-current areas benefit from permeable options, while containment-focused projects need non-permeable barriers.
  • What are Turbidity Curtains made out of?
    Turbidity curtains are typically made from two main materials: PVC Fabric (Impermeable) – A heavy-duty, non-permeable material that completely blocks water flow, trapping sediment within a contained area. This type is ideal for projects requiring maximum containment, such as dredging and marine construction. Geotextile Fabric (Permeable and Non-Permeable) – Permeable geotextile turbidity curtains allow some water to pass through while filtering out sediment. These are useful in areas with strong currents where complete water blockage could cause excessive strain on the curtain. Non-permeable geotextile curtains function similarly to PVC curtains, containing sediment but offering different durability and flexibility advantages.
  • Are Turbidity Curtains permanent?
    With the proper care and maintenance, BMP turbidity curtains can be a long-term investment in your job. While not meant to be a permanent solution to turbidity control, these curtains can help manage runoff sediment during inclement weather, or while you’re implementing longer term erosion solutions. With time and natural wear and tear, a turbidity curtain may become less effective as it’s exposed to rough seas or heavy currents. Holes may form in the plastic or floaters, and anchors or grommets may become dislodged. If unmonitored, a runaway silt curtain can contribute to murky, polluted waters itself.
  • Do I need a Floating Boom or Turbidity Curtain?
    Boom are used to contain substances (oil, trash, seaweed, logs, or other debris) floating on the surface of the water. On the other hand, turbidity curtains are used to contain both floating debris and for sediment control when it is suspended beneath the surface of the water. BMP Supplies both floating Booms or Curtains.
  • How do I install Turbidity Curtain?
    Review BMP Supplies Turbidity Curtain Install Instructions HERE
  • Can I reuse a Turbidity Curtain?
    BMP Does not recommend reuse but it some cases a floating curtain can be reused as long as they are properly cleaned and are not previously used with materials that are contaminated. If you are using this turbidity curtain in a location that is dealing with contaminated materials, please make sure that your curtain is properly decontaminated before reuse.
  • What site conditions do I need to evaluate for using a Turbidity Curtain?
    Wind, waves, and current: For many locations the three most influential factors on the silt curtain are wind, waves and current. Depending on where your work area is located these factors can act as a force on the turbidity curtain causing it to move and adjust while installed. This, in turn, can limit the turbidity curtain's ability to contain silt and sediment in a given location. ​ If you are dealing with a site that has any of the above conditions a Type 2 or Type 3 silt curtain will probably work best for your area. These silt curtains include the addition of a single or dual tension cable along the top of the curtain. This increases the strength of the curtain and its ability to hold up to moving water areas. ​ Consider Anchoring: The second thing required for any moving water condition is effective anchoring. Spacing and anchor types will change by area, but should typically include, at a minimum, shoreline anchors and anchoring along the barrier every 50' or 100'. ​ Review BMP Supplies Anchoring Kit HERE
  • How does a Turbidity Curtain’s depth affect its effectiveness?
    The depth of a turbidity curtain should be carefully matched to the water conditions. A curtain that is too short may allow sediment to escape underneath, while one that is too long can drag on the bottom, causing damage and reducing efficiency. Proper anchoring and tensioning help maintain the right depth.
  • Can Turbidity Curtains be used in tidal areas or strong currents?
    Yes, but special considerations are required. Floating turbidity curtains in tidal zones or areas with strong currents need reinforced anchoring, tensioning systems, and sometimes multiple layers to prevent sediment bypass. High-flow models with permeability features can also help manage water movement while trapping sediments.
  • What are the key differences between Type I, II, and III Turbidity Curtains?
    Type I: Best for calm waters like ponds and small lakes with minimal current. Type II: Designed for moderate conditions, including inland rivers and harbors with some current and wind exposure. Type III: Built for strong currents, coastal waters, or high-flow construction zones, often using reinforced fabrics and extra flotation.
  • How do you prevent a Turbidity Curtain from sagging or sinking?
    Properly spaced floats, weighted ballast chains, and periodic maintenance checks help prevent sagging. Ensuring the curtain is the correct length and tensioned appropriately between anchor points also minimizes sinking risks.
  • Do Turbidity Curtains impact aquatic life?
    While turbidity curtains help protect ecosystems by controlling sediment spread, they can also temporarily restrict fish movement. Environmental assessments and strategic placements with escape routes help minimize disruptions to aquatic life.
  • How does cold weather affect Turbidity Curtain performance?
    Ice formation and freezing temperatures can make materials brittle and damage curtain integrity. Special cold-resistant materials, extra buoyancy, and seasonal removal strategies help maintain effectiveness in winter conditions.
  • How do you properly anchor a Turbidity Curtain?
    Anchoring systems should be selected based on water depth, current strength, and wind exposure. Options include stake anchors for shallow waters, concrete blocks for deep waters, and weighted buoy systems for fluctuating depths. Regular adjustments ensure stability.
  • Are there regulations governing Turbidity Curtain use?
    Yes, regulations vary by region and project type. Environmental agencies like the EPA (U.S.), Fisheries and Oceans Canada, and local water management authorities set standards for turbidity control during construction. Compliance ensures permits are maintained and environmental fines are avoided.
  • How do Turbidity Curtains compare to Silt Fences for sediment control?
    Turbidity curtains control sediment in water, while silt fences manage runoff on land. Both serve erosion control purposes, but turbidity curtains are necessary when working directly in or near bodies of water to prevent sediment from dispersing downstream.
  • What is catch basin protection?
