Geotextiles
Light Weight Nonwoven Geotextiles
Most lightweight nonwoven geotextiles (3 oz. To 4.5 oz.) are used as filter fabric in subsurface drainage applications. High flow rates and small openings are what make these geotextiles ideal as filter fabrics. Wrapping a nonwoven filter fabric around the drainage system allows water into the drain while preventing soils from clogging the system.
In addition to drainage, lightweight nonwoven geotextiles are often used as landscape fabric, weed barrier or for lightweight separation under pavers.
Another use for lightweight nonwoven geotextiles is as asphalt overlay. These particular geotextiles are designed to hold tack coat and withstand extreme temperatures. Placing an overlay fabric between the old asphalt and the new overlay reduces reflective cracking and extends the life of the asphalt. A moisture barrier that protects the overlay from water intrusion is created when the geotextile absorbs the tack coat.
