Silt Fence sediment and pollution run-off control
A silt fence, sometimes called a “filter fence,” is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff.
Greenfix 70SF Silt Fence is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in storm water runoff.
Silt-Stop 70SF is a high quality woven polypropylene geotextile made of 100% polypropylene staple fibers. Silt-Stop 70SF is produced from individually woven polypropylene fibers and provides superior tensile strength and low elongation. Silt-Stop 70SF resists ultraviolet deterioration, rotting, biological degradation, naturally encountered basics and acids.

Why do you need a Silt Fence?
All states in the U.S. have laws requiring installation of erosion and sediment controls (ESCs) on construction sites of a specified size. Federal regulations require ESCs on sites 1 acre (0.40 ha) and larger. The sediment controls must be installed before the beginning of land disturbance (i.e. land clearing, grubbing and grading) and must be maintained during the entire disturbance phase of construction.
In 2007 The Environment Agency published Pollution Prevention Guideline 5 (PPG5) on “Works and maintenance in or near water”
Point 2.1c states that “Exposed ground and stockpiles use silt fences at the toe of the slope, made from geotextiles, to reduce silt transport”.
This is becoming increasingly enforced and will in time have the force of legislation. The guidelines can be downloaded below.
