The characterization of geosynthetic\/geosynthetic interfaces can now be performed faster than ever, thanks to the development of an innovative testing concept at SAGEOS.<\/p>\n<\/div>

Did you know that SAGEOS develops advanced measurement solutions tailored to market needs? As part of a research project, an experimental device was designed and manufactured to evaluate the resistance and friction properties of textured geomembrane interfaces using an inclined plane mounted on a dynamometer.<\/p>\n<\/div>

Addressing the challenges of Containment structures<\/strong>
\nThis device is specifically designed to characterize the friction properties of geosynthetic interfaces in critical applications such as engineered landfills, mining ponds, and leaching platforms, where significant mechanical stress may be applied. The setup replicates real-world installation conditions, where a pre-inclined plane is subjected to increasing normal stress until the carrier plate moves.<\/p>\n

A step forward from standard methods<\/strong>
\nOur apparatus uses an inclined plane under compression. Installed on a dynamometer, it allows testing of interfaces under high normal stresses\u2014up to 5000 kPa\u2014while providing better representation of real conditions.<\/p>\n

During the test, two scenarios may occur:<\/p>\n
