During the construction of a new 400-acre industrial park in Cambridge, Ontario, environmental control measures were required to protect a wetland from the impacts of silt and sediment. Turbid water is hazardous to native wetland species like fish and beavers. To mitigate these issues, the site servicing contractor contacted Layfield for guidance on selecting and installing a temporary floating barrier to help protect the wetland.
Layfield assessed the site requirements and recommended the FSC MTO Turbidity Curtain, which exceeds the Ontario Provincial Standards. The FSC MTO is a high-visibility temporary floating barrier consisting of prefabricated curtains, each measuring 2.28m deep x 15.23m long. The curtains are connected in series using the male/female flap to create a 91m seamless curtain to prevent silt escape.
The curtains were fabricated by Layfield in our Canadian facility and included a nylon load line and ballast chain pocket to keep the curtain plumb and secure during operation. The curtain was deployed in a single length across the pond using two small boats and tied off to the shoreline at 2 anchor points.
The installation crew deployed several 20lb marine mushroom anchors and floats to keep the curtain in position. Furling lines were used to adjust the curtain depth and contour of the pond. The installation was efficient and only took one day to complete.
The client is very pleased with the end result of the installation and performance. Shortly after the installation of the barrier, a high wind event was experienced in the area, and the curtains remained in place and securely anchored.
