Turbidity Curtain Selection Guide

GEI Works Turbidity Curtain Options & Types of Curtain

Which type of turbidity curtain do you need? There are many important factors to consider when selecting the type and grade of turbidity curtain for your application. Use the turbidity curtain selection guide chart below to help you find the best option for your project. All Triton Turbidity Curtains are made in the USA, and we keep lots of curtain in stock, ready to ship when you order.

Turbidity barriers are floating barriers designed to contain and control the dispersion of silt suspended within the water column. We also manufacture products for other types of marine applications, such as Boom (for surface debris, pollutants, and oil), Water Baffles (for directing or slowing water for sedimentation), and Diffusion Mats (for minimizing the impact of water and resulting turbidity).
