14 ga silt fence, sometimes (misleadingly) called "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.
To Properly Install 14 ga Silt Fence - Unroll fabric, stretch and
drive stakes into the ground. Make sure the stakes are on the
downside of the slope or facing away from the sediment. The bottom
of the fabric should be buried at least six inches under the soil
to prevent the sediment from escaping underneath the fencing. If
connecting more than one section make sure the last stake of the
first section is interlocked with the first stake of the next
section. This overlap will help contain any runoff at the
intersection of the two sections of the fencing.

2. Common Size of 14 ga Slit Fence
Wire Backed 14 ga Silt Fence has filter fabric attached to wire
mesh for added support. The most common silt fence fabric is 70
gram and 100 gram and the wire is usually 14 gauge or 12.5 gauge
wire with a 2"x4" or 4"x4" opening size. Most commons roll sizes
are 24"x100' and 36"x100', but some states and DOTs require special
sizes. Metal Erosion Posts are usually used to hold wire back silt
3. Installation of Silt Fence
14 ga Silt fence is designed to pool water on your site while
sediment settles out of it. In order for your silt fence to be
effective, the fabric must be trenched at least six inches into the
ground so that it will contain stormwater on your site (see diagram
below). There are also machines that will slice the fabric into the
ground. The slicing method of installation is typically faster and
more effective than trenching. While this may be a big investment
initially, in the long run it can save a significant amount of time
in both installation and maintenance.
4. Where to Place It
14 ga Silt fence should be used down slope of a disturbed area. It
should be aligned parallel to the contours of the slope, with the
ends of the silt fence curving uphill. Leave some room between the
silt fence and the toe of the slope so there is more of an area for
the water to pool.
14 ga Silt fence must be maintained to be effective. Check your
silt fence regularly to make sure it will hold water during a storm
event. Additionally, if your silt fence is working properly, it
will eventually fill up with sediment. When the sediment is halfway
up the fence, it will need to be cleaned out so that there will be
room for the water to pool.
