  • Creep not a factor for Geocell load support

    An accurate understanding of creep resistance is essential to proper material selection when using polymers, and in the case of geocells, this science is being misapplied.  The definition of creep deformation is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stress.  Creep is something that creates fear and uncertainty with all ...

  • Climate change is more than a tech problem, so we need more than a tech solution

    At the COP 21 climate convention in Paris at the end of 2015, leaders from 194 nations agreed to pursue actions that will cut greenhouse gas emissions enough to keep global warming within 1.5 °C (2.7 °F) above pre-industrial conditions. Meeting this goal will avoid continued and increasing harm to people and ecosystems around the world caused by a changing climate, and it is also a great ...
