Engineering properties of geotextiles

The properties of geotextiles can be classified in three ways mechanical, hydraulic, and chemical. Some of the important geotextile properties are discussed below. 

When a geotextile subjected to concentrated forces normal to the plane is kept under pre-tensioned conditions, the distribution and magnitude of these forces result in the puncture failure. In general, a biaxial tensile failure simulates puncture failure more appropriately than uniaxial tensile tests. The puncture properties of geotextiles are significantly affected by the fabric and soil parameters.  

The deformation behaviour of geotextiles under compression loading is highly complex in nature, as multiple types of deformation of constituent fibres occur at micro-level based upon the type of geotextile. The fist of deformations occurring at the micro scale can include bending, shear, tensile, and torsion.
