Expandi® silt curtain barriers are designed to control the
settling of solids suspended in the water column usually
created during construction or dredging operations. The use
of silt curtain booms reduces the impact of the suspended
solids in the aquatic environment.
The silt curtain is a geotextile fabric screen attached to the
skirt of the boom by using high frequency weldings. The
curtain let the water pass through it but not the suspended
solids. To ensure the vertical position of the curtain, a ballast chain is installed along a bottom hem. Due to
the special size of this curtain, also vertical ballast would be fitted.
The boom has a section length of 30 m and is connected to the silt curtain high frequency welding, besides
silt curtains sections are connected each other with ropes and/or shackles.
