LP200 Filter Fabric 17.5' x 309' (woven)
Layfield
#LP200
Layfield Geotextile Filter Fabric. Woven Polypropylene slit-film geotextiles are used for subgrade stabilization and other applications requiring strength. Geotextiles allow water to flow relatively freely. Using high strength synthetic filaments we can reinforce earth structures while allowing water to drain. Geotextiles allow us to build roads, walls and embankments where it was not possible to build in the past
Standard woven slit-film polyproylene geotextiles, usually called "wovens" are an economical range of geotextiles that combine high strenth with low cots. These materials are made by weaving pre stressed polyproylene tapes in a simple weave pattern. The resulting fabric has a high strength to weight ratio. Slit-film wovens are used in roadbuilding and embankment construction. Slit-film wovens are excellent seperators and help to speed construction. Split-film woven geotextiles primary funtions include seperation, and reinforcement. While their secondary functions include filtration.
- Separation function:separation of two layers of soil with different soil physical properties, such as road gravel from soft sub-base materials.
- Filtration function: retaining fine particles when water passes from a fine-grained to a coarse grained layer, such as when water flows from a sandy soil into a geotextile wrapped gravel drain.
- Drainage function: to drain liquid or gas in the plane of the fabric which results in draining or venting of the soil, such as a gas vent layer in a landfill cap.
- Reinforcement function: improving the load bearing capacity of a soil structure, such as a high strength geotextile to reinforce a retaining wall.
- Protection function: mechanical protection of geomembranes against perforation and abrasion, such as a liner protective layer when only gravel fills are available.
