Description

What is Geos Silt Protector?

Geos Silt Protector is a silt curtain installed in water for preventing spread of environmental contaminants induced by coastal and riverside construction. It is proven that the preventive effect of contaminant spread by Geos Silt Protector is at a minimum of 45% to a maximum of 95%.

Silt protectors usually consist of float, canvas and anchor parts and Geos Silt Protector is supplied in the unit set of assembled float and canvas parts. Geos Silt Protector is made secure in structure so that it can well stand large surges of energy such as tides, waves and wind.

No recycled materials are used for Geos Silt Protector. Especially, floats made of recycled materials may cause a serious loss of buoyancy due to faster absorption of water after the installation of silt protector.
