The real measure of TerraFlex™ EPS Geofoam as a cost effective light weight fill is best illustrated by the following graph, where TerraFlex™ is shown to be at least 5 times more cost effective as a light weight fill than any other material! Is it any wonder that EPS Geofoam has been the light weight fill of choice for highway engineers in all of Europe and Japan for the last 15 years?

The following table shows type XI TerraLite™ (the softest geofoam). Other Densities will be posted as the data becomes available.

Most Geofoam applications do not intentionally load the material past 1% strain, commonly believed to be the elastic strain limit.
