Filter fabric, 5'x360.9'

What is filtration geotextile?

Filtration (in geotextiles) is the process of retaining soil in place while allowing water to pass from the soil; removal of particles from a fluid stream.

Fitration fabric is a nonwoven geotextile made up of polypropylene fibers. These fibers are needle punched to form a stable and durable network such that the fibers retain their relative position. It is non-biodegradable and resistant to most soil chemicals, acids, and alkali with a pH range of 3 to 12. Our filter cloths are manufactured to meet or exceed the minimum average roll values required by ASTM.

Usage of filtration fabrics

They are used for filtration in a variety of sructures: as french drain filter fabric (depending on the soil type), as well as for silt fence, foundation walls and pipe wrap. Our fabrics, 4.2 oz fabrics, RM150, are equal to 140NC, 130EX, 270R, LP4, 160, 7607, 4546.

When building a retaining wall, make sure that the filling material behind it drains easily, otherwise heavy wet backfill will add pressure on the wall leading to the wall fail. To protect drainage stone behind retaining wall from clogging it is recommended to cover the drainage stone layer with filtration fabric. Without filter protection, fine-textured soils will gradually accumulate between the pieces of drainage stone, and the drainage for the retaining wall fails. In the case of significant water flow, use perforated pipe wrapped into filter fabric to redirect the flow (picture below).
