Choosing a Silt or Turbidity Curtain Type

The first thing we need to decide is which type will be best for your application.

This decision is based on site conditions, water velocity, waves (height, frequency, etc), wind speed and direction, tides, soil type (is it contaminated?), project duration, and site specific requirements and project specifications.

As a general overview, silt curtains increase in strength and capabilities as the types increase. The Type 1 Silt barrier is used in calm water conditions where there is no flow, while the Type 3 Silt Barrier is used in the roughest areas, such as locations with a fast current or high waves.

Your boat launch in located at the windward edge of a lake, so initially we would recommend a Type II Silt Barrier. It is specifically designed for in-water control of silt and turbidity around dredging activities, pile driving rip-rap installation, demolition work, etc. The rugged yet economical floating silt curtains designs make them a contractors project favorite for moving water < 1.5 knots and 36” Wave swells.

Standard barrier sizes are 100' and 50' Long Sections x 5' Wide. Depths range from 3 feet all the way to 100. Custom design and sizing is available and often required for various projects.
