SILT SCREEN
Basically, the Silt Protector has been developed to protect the natural environment and maritime resources from the harmful influences caused by the outflow and diffusion of the used dirty
water from dredging and reclamation work at the ocean and the rivers.

The Silt Protector is a kind special screen which is made up of High-in-tensity synthetic fiber and has the structure to prevent the outflow and the diffusion of the used dirty water through
filtration, interception and precipitation of the particle around the construction area.

The Silt Protector is divided into FLOAT, CANVAS and ANCHOR part.
FLOAT
  FLOAT is the structure that can make CANVAS and CHAIN float on water. The structures which can be used widely are
excellent buoyant TUBE TYPE Structure in POLYSTYREN and COVERING HEAD TYPE structure where durable HDPE COVER can be disjointed and assembled.

Canvas part
  CANVAS is the part that makes a barrier in the water. It is made up of High-in-tensity synthetic fiber and should have the filtration function that is durable against the external force.

 Anchor part
ANCHOR is needed to prevent the movement of the SILT PROTECTOR from the external force, such as wave, wind and current. It will be located on the seabed or river bottom and connected to CANVAS PART in order to make CANVAS PART stay on the fixed place. The size and the type of the ANCHOR will be determined from the site condition.
