IV. Test Principle

The specimen is securely clamped between the upper and lower clamps, with an elastic diaphragm positioned beneath the specimen. Water pressure is gradually applied to the diaphragm, causing the specimen to deform and eventually burst. The maximum pressure reached at the moment of specimen failure is recorded as the bursting strength. The test results can be used to evaluate the mechanical resistance and bursting performance of geotextiles.

V. Applications

The Geotextile Burst Strength Tester is suitable for testing woven and nonwoven geotextiles used in filtration, drainage, separation, reinforcement, erosion control, and other civil engineering applications. It is widely used by geotextile manufacturers, construction material laboratories, research institutes, universities, and third-party testing organizations.
