About Geocells

GEOSYNTHETIC MATERIAL SERVICE PROVIDER

UNDERSTAND GEOCELLS

A key indicator that determines whether a project will collapse or subside in 20, 50 years or even longer.

ESCR ≧5000H is an abbreviation for Environmental Stress Cracking Resistance. It is one of the most important indicators for evaluating the long-term lifespan of polymer materials (such as HDPE).

Many substandard cell blocks have high strength when they are first laid, but because a large amount of recycled materials are used, their ESCR value is extremely low. After 3-5 years of operation, the cell blocks may break off like biscuits, causing the entire subgrade to fail.

Seven-day suspension test (weld joint creep test)

The welded joints of geocells are subjected to constant, long-term tensile force during engineering. While the instantaneous pull-out strength (from a sudden, forceful breakage by machine) is very high, this does not mean it won’t gradually detach under long-term stress. This phenomenon is called **creep**.
