When it comes to geocells, it’s important to test their elastic behavior, since it’s the geocell’s elasticity that will determine its ability to maintain its shape after it has been compressed or applied with loads.
Geocells must maintain their elastic properties without permanent deformation or loss of geometry, which could result in losing confinement or even worse- crack and fail.
The elastic behavior of a geocell includes its stiffness.
Geocells with high stiffness will resist better to deformation when force is applied on them. The stiffer a geocell is, the more chances it has to resist permanent deformation.

Elastic Behavior Test

The standard test for geocell elastic behavior is called Dynamical Mechanical Analysis (DMA), and it examines the elastic modulus of polymers.
This test extracts the geocell stiffness, in other words- the ability to apply loads on the geocell without permanent deformation.

Elastic Behavior of PRS-Neoloy Tough-Cells

PRS-Neoloy Tough- Cells demonstrate higher elastic modulus which results in less permanent deformation and provides better performance over the long-term.
