Filter fabric is a geotextile material made from needle punched
polypropylene polymers which are chemically and biologically inert.
Filter fabric looks and feels similar to felt.
Filter fabric will not decompose in soil due to bacterial or
fungal action. In normal use, it is unaffected by acids,
alkalis, oils, and most chemical solvents. The primary
functions performed in a geotechnical application are drainage
(filtration), soil separation (confinement), soil reinforcement
(load distribution), and above or below pond liners to prevent
Filter fabric provides a perfect base for rip-rapping under
stones or rocks on the shoreline of lakes and ponds to prevent
shoreline erosion. Filter fabric may be used to aid in
limiting emergent and submerged vegetation (i.e. cattails).
Filter fabric prevents excess soil from washing into the water and
deters muskrat burrowing.
Filter fabric provides an excellent base under sand or pea stone
in beach areas, along shorelines, and in the water. Filter
fabric provides a barrier between soft bottoms and your chosen
beach material. Filter fabric will not allow the two
materials to mix, and due to its load distribution effect, swimmers
will not sink into the substrate. A solid benthic layer is
Filter fabric provides an excellent base for pea stone or gravel
when adding spawning habitat for fish. The filter fabric
prevents gravel from sinking into the bottom substrate.
Filter fabric is frequently used under pond liners to prevent
rocks, jagged stones, or other sharp materials from puncturing pond
liners. Filter fabric is also used on top of liners around the
pond perimeter as a base to protect the liner side slopes from
rocks/stone punctures, rip-rapping, and to help hold sand, stones,
or rocks on the steep side slopes.
In some pond liner installation sites filter fabric may be
required to act as an underlayment providing extra
protection underneath the primary liner. Having an
underlayment can prolong the life of your liner, protecting it from
any sharp objects that can possibly puncture the liner, making it
more durable and long lasting.
Filter fabric is not susceptible to biological or chemical
breakdown. Filter fabric lasts years though it is important to note
this material is not UV protected and should be covered as direct
exposure to sunlight will break it down over time.
Standard size rolls are 12 ½' x 360' and 15' x 300'. Filter
fabric can be cut to any length. Custom welded filter fabric panels
are available to match your liner dimensions making installation
easier and more convenient for you. Custom panels save you time and
money in the process.
8 ounce filter fabric is ideal for most applications but it is
also available in in 4 or 12 ounce rolls.
