The TSD is used anytime the flow of runoff water needs to be stopped, slowed, or diverted. Typical applications of TSD include replacing straw bales for checking runoff water flow in a newly constructed ditch, or creating a temporary flow path through an earthwork project. The patented TSD design provides an effective, reusable sediment control system. The Triangular Silt Dike is constructed with a polyurethane foam core, wrapped in a woven polypropylene fabric. This durable design is lightweight for mobility and ease of installation. A standard 7-foot section of TSD weighs just 8 lbs. The vertical height of TSD when installed is roughly 9 inches. When you wish to move the TSD sections simply allow the water to drain from the foam, and maneuver the sections to the new location. TSD sections can be quickly washed and drained of water, restoring them to their original condition for reuse or storage.
