The Geotextile Industry

The geotextiles industry has many similarities to the nonwovens and textile industry. Despite the differences in the usage (geotextiles are used to control erosion in construction activities; nonwovens are used in personal products, clothing, etc.), both industries are interested in assessing the physical properties of their materials.

PMI manufactures instruments which allow researchers to predict the size of particles (e.g., dirt) which pass through the geotextile. This geotextile acts as a barrier for particles of a given size and allows free passage of smaller particles or fluids (e.g., water). Knowing the pore size distribution from instruments in the PMI Porometer product line is a direct test for the performance of the geotextile in the field.
