TerraFlex™ was developed specifically to be a synthetic compressible inclusion (SCI) with engineered, well defined properties. It is significantly softer than the lowest density Geofoam available and it has a much higher elastic strain limit of 10-20%. Additionally, it's long term behavior, under sustained load, reveals it to be significantly more compressible than any other material, including all densities of ordinary EPS geofoam.
TerraFlex™ is manufactured by GeoTech Licensees using a process patented in 1998. TerraFlex™ will serve as an elastic, compressible layer between the earth and rigid structures. It has been tested under conditions of rapid cyclic loading as well as long term loading to determine it's behavior in every potential application. It has seen use in the following applications:
