These geotextiles are specially woven with high Percent Open Areas (POA) for maximum resistance to clogging and were the first to be used and specified by the USACOE.
High strength geotextiles designed for those challenging applications when filtration/hydraulics, high durability, and higher tensile strengths at low strains are essential.
What really matters in long-term filtration performance? Which of the four most standard fabric types best resist clogging? What is the best current means available to evaluate and quantify the clogging potential of geotextiles?
The American Association of State Highway and Transportation Officials (AASHTO) M-288-00 Specification lists physical properties for geosynthetics under varying soil conditions.
