A woven geosynthetic fabric is disclosed having a first weft yarn, a second weft yarn, and a stuffer pick woven in the weft direction of the cloth. A warp yarn interweaves the initial and second weft yarns and the stuffer select. The very first weft yarn and the second weft yarn using distinct cross-sectional shapes. At least a part of the cloth has a plurality of weft yarn sets with stuffer selections respectively disposed and woven between the weft yarn sets. Every weft yarn set has two first weft yarns and 2 second weft yarns. Among the two first weft yarns is adjacent among both second weft yarns and piled on the other second weft yarn. The next second weft yarn is piled on another first weft yarn.

BACKGROUND

 
Woven polypropylene geosynthetic fabrics are utilized to reduce the flow rate of water and maintain soil retention. Frequently such cloths are used to establish a stable foundation for street ways. Therefore, water flow throughout the fabric and dirt retentionby the fabric are significant attributes. Moreover, the fabric should have enough electrical for durability, especially when the fabric is subjected to loads.
 

 
But, water flow rate and dirt retention are at odds with cloth power. Ordinarily, to increase strength, the pores of the cloth are reduced. As a result, the cloth is limited to the amount of water which can pass through the cloth and,as a result, the size of this soil particulates it could retain. If greater flow rates and larger particle size retention are desired, the cloth has to yield on strength due to reduced cloth density. Accordingly, there is a need for a woven geosyntheticfabric that has improved strength for durability while maintaining relatively high flow rates and chemical retention. It is to solving this and other needs the current invention is directed.
