Ecobarrier Silt Curtains

Control and Contain Silt and Sediment -

Our Ecobarrier Silt Curtains are designed to contain the fine particles of silt that are discharged into the water from dredging, construction or reclamation activities.

Silt curtains (also called turbidity curtains, silt screens or silt barricades) are vertical barriers positioned within the water to contain the fine particles of silt that are discharged into the water from dredging, construction or reclamation activities.

Ecocoast was the first manufacturer of the full range of silt curtains in the EMEA region, under the brand Ecobarrier™. The Ecobarrier Silt Curtains are manufactured in the UAE, which reduces regional shipping times and costs, and can be tailored to suit specific conditions and project requirements.

Having a contracting background, we understand both the design and installation requirements, and specifically design our Ecobarrier Silt Curtains for durability, ease of installation and long-term use to reduce replacement and repair costs. We manufacture the strongest silt curtains in the world, meaning that at the end of each job, they can be recycled and reused instead of winding up in a landfill.

Ecobarrier Rigid Frame
ApplicationsType I is the most economical curtain. It is designed for short-term installations in sheltered waters with low tidal flow and minimal waves.Type II is the most versatile curtain, designed for longer term installations in sheltered waters or areas with moderate tidal flow.Type III is designed for rougher waters, stronger currents or long duration installations, due to increased strength and buoyancy.Type IV is the offshore version, designed for offshore conditions with strong currents and moderate waves. The Type IV curtain is designed for multiple re-use.For use with grab or backhoe dredger. Suitable for repeated, long-term use in various marine environments.


Ecobarrier Silt Curtain - Type I

Type I Ecobarrier Silt Curtain is a light-weight inshore curtain that is ideal for lower energy environments and sheltered deployments with no significant wind or currents.
