Product Details
The needle-punched non woven geotextile is produced from polyester or polypropylene fiber by different equipment and technology to get different thickness.
Geotextiles play an important and crucial role in the civil engineering works.
The wide spectrum of geotextiles and related products that are available to civil engineers to solve a wide range of problems along with their functions and possible applications.
Geotextiles are permeable textile structures made of polymeric materials and are used mainly in civil engineering applications in conjunction with soil, rock and water.
