Before you begin.

  • No curtain can hold back flowing water. Install the curtain in a manner that minimizes the flow against the curtain.

  • The curtain will move with the wind. Take wind direction into account as best you can.

  • Taking water current and wind into consideration, install the curtain so the fabric will be pushed against the cable under the floatation and not away from it, which puts less strain on the webbing attaching the cable to the curtain.

  • The curtain end anchor point(s) on land should be determined and built before the turbidity curtain is put in the water. IMPORTANT: Do not attach the curtain on shore to the top anchor eye loop. Those are only for attaching to anchors in the water, the curtain will tear away from the connector plate. Use tow bridles on shore or make sure the tension on the curtains is in line with the cable.

  • Determine where the curtain will enter the water. Most contractors assemble the curtain sections at one location on shore, put the curtain into the water at the same spot, and then pull the now connected curtain further into the water from one end. Depending on the site and the distance from shore the curtain will be anchored, it may be easier to stretch out the curtain on the shore line and then put the entire length into the water. In either situation:

    DO NOT CUT THE TWINE THAT HOLDS THE CHAIN TO THE FLOATATION till the curtain is in place in the water. Each 50 ft. curtain section is bundled separately. If the sections are not alike, they will be clearly marked as to the skirt depth. If a shore section(s) has been ordered, where the skirt depth changes from one foot to 5’, 7.5’ or 10’, identify the section(s) and connect to the beginning and end of the assembled curtain.



  1. Lay out the sections to be joined. At the site the curtain will be assembled, place a 50’ section of curtain on the ground with the cable (not on Type 1 DOT) in the loops below the floatation visible on top of the fabric. Cut the white strapping that holds the bundle together. Where the sections are to be joined together, cut the twine that holds the fabric and weight chain on the end of the section until the skirt fabric can be fully stretched out. Cut as few twine ties as possible. Place another 50’ section of curtain in the same manner where the section can be joined together making sure the cable is on top of the fabric.

  2. Join the sections. The aluminum universal connectors (only on HD curtains) are connected first. One side slides into the opposing side and the toggle pin is inserted to hold the sections together. The remainder of the curtain sides will have yellow paint circles drawn (Type 1 IND) to locate the burned hole just inside the sewn in rope or Grommet holes (Type 2 DOT). Starting from the top, match the burned holes (or grommet holes) and connect one section to the other with the black cable ties supplied. Locate the ends of the weight chains and connect the weight chains together with the carabineer attached to one of the chain ends.

  3. Re-tie the curtain. Bunch the now connected curtain fabric and chain back to the floatation and re-tie the fabric and chain to the floatation again so the curtain can be floated to its final position in the water. Repeat for each section to be joined. IMPORTANT – BUNCH UP THE NOW CONNECTED FABRIC AND LINKED CHAIN AND RETIE BACK TO THE FLOATATION BEFORE TOWING OR DAMAGE WILL RESULT.

Depending on the site and curtain length, it may be necessary or advantageous to assemble larger already joined sections in the water as assembled curtains of hundreds of feet in length are difficult to pull around. This can be done, but is easier to do once the installation team has assembled individual sections on land to see the procedure.


Float into position.​

  1. Float and stretch the curtain into place and anchor to the shore and to anchors in the water as deemed necessary. The connector plates (HD Curtains Only) have an eye bolt on each side of the curtain for this purpose.

  2. Once the curtain is in place and anchored as necessary, cut and collect the twine, dropping the curtain skirt and chain into the water.
