TURBIDITY BARRIERS

TYPE I
This is our best selling Turbidity Barrier. Its best application is construction sites located in protected areas that are exposed only to light winds and to currents with velocities of less than one foot per second. Typical sites may include: ponds, shallow lakes, small streams and marshes. Anchoring may be required to keep the barrier in place; these usually consist of concrete blocks or stakes. Barrier sections are connected by rope lacing or nylon ties which must purchased separately.

TYPE II
This barrier is more rugged than the multipurpose Type I. Designed for more severe environments, it has a top load cable and special stress plates for reinforcing the corners. Typical sites may include: lakes, streams, intercoastal and tidal areas where current s with velocities between one up to five feet per second are expected. The anchorage and installation is dictated by the site conditions. We can help you determine the right design!

Barrier sections are connected by rope lacing or nylon ties which must be purchased separately.

TYPE III
This is a modified version of our Type II barrier. We replace approximately 20 % of the barrier skirt fabric area with a polypropylene filter fabric that are consistent with most state DOT specs. The filter fabric is used to reduce curtain pressure while retaining silt. A filter fabric which is woven tightly enough to retain silt will not significantly reduce pressure on the curtain. However, if the filter fabric is woven loose enough to reduce the pressure on the curtain it would not be able to retain most silt and sediment particles. Also, the filter fabric cannot be heatsealed, and must be sewn into the curtain, resulting in a reduction in curtain strength and longevity.
