.What is geotextile fabric used for?
Here are some common uses of geotextile fabric:
- Road construction – It’s often used under asphalt roads to separate and stabilize the road base from weaker native soils below. This prevents mud pumping.
- Erosion control – Geotextiles are placed on slopes, embankments and drainage ditches to keep soil in place while allowing water to pass through.
- Retaining walls – The fabric is installed behind retaining walls to prevent small soil particles from passing through the wall while allowing water drainage.
- Drainage applications – lightweight geotextiles serve as filters or separators around drainage trenches, French drains and under leach fields.
- Landfill construction – They are used in lining landfills to prevent liner/soil punctures and allow collected leachate to drain out.
- Rehabilitation of soft soils – Geotextiles help stabilize weak soils under building foundations and parking lots through reinforcement.
- Laying sod/seeds – The fabric retains moisture and topsoil below newly laid grass or seeds until roots establish to prevent erosion.
- Railroad construction – Used under railroad ties and ballast materials to separate and stabilize the subgrade soils.
So in summary, geotextiles serve as filtration layers and reinforce weak soils across many civil engineering, infrastructure and landscaping applications. Proper selection depends on the specific demands of the project.
