Geotextile Fabrics
Geotextile fabrics are a proven solution for a wide variety of civil and environmental engineering challenges. Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven, needle punched, or heat bonded. The addition of a geotextile fabric to the design of a roadway can provide savings from several factors, including reduction of both excavation and base materials. Geotextile fabrics also enable construction to progress under difficult field conditions that would otherwise make work impossible.
Nonwoven Geotextiles are composed of polypropylene fibers which are formed into a stable network such that the fibers retain their relative position. They are inert to biological degradation and resist naturally encountered chemicals, alkalis, and acids. Nonwoven geotextiles provide excellent physical and hydraulic properties that are good for separation, drainage, and erosion control. Commonly used as filter fabric, pipe sock, trench drains, and rock slope protection.
Woven Geotextiles are composed of high-tenacity polypropylene yarns which are woven into a stable network such that the yarns retain their relative position. They are inert to biological degradation and resist naturally encountered chemicals, alkalis, and acids. Woven geotextiles provide excellent puncture and work well for separation, stabilization, filtration, and reinforcement. Commonly used for pavers and bank stabilization.
High Performance Woven Geotextile are composed of high-tenacity polypropylene yarns, which are woven into a network such that the yarns retain their relative position. These geotextiles have a high tensile strength and soil interaction while also providing a flow characteristic of a fine to coarse sand layer. High Performance Geotextiles are commonly used on soft foundations, soil stabilization for roads and railroads, and earth reinforcement.
