Woven Geotextile Fabric for Dirt Roads | Haul Road .

Woven geotextile fabric is permeable, strong, and reduces aggregate. A geotextile underlayment allows water to flow through gravel or a thin layer of dirt to the soil underneath, and it prevents rutting and erosion. Mud control is easier using a geotextile filter fabric for drainage, since there is less dirt and soil to become liquefied.
