Expert Commentary
Governs the Grab Breaking Load and Elongation of Geotextiles. This is a quick-check quality control test using 25.4 mm (1 in.) wide jaws on a 100 mm wide specimen. The technical focus is on the Effective Strength. Because only a portion of the fabric is clamped, the surrounding fibers provide a lateral reinforcement effect. MTO’s pneumatic action grips are essential here to maintain a constant clamping pressure on thick, non-woven materials that tend to compress during the pull. This is a high-volume lead for textile mills and on-site construction labs.
