Application

Geo-textile Effective Aperture Tester is used to determine the apparent opening size of a single layer geotextile or geotextile-related product, using the wet-sieving principle. A quantity of graded glass beads is brought on the surface of the geotextile and washed through with water. The geotextile acts as a sieve and the graded glass beads, which act as soil and pass the geotextile, is analyses. The characteristic opening size (O90) of the geotextile corresponds to a specified sized of the graded glass beads passed (d90).
