TerraFlex™ Synthetic Compressible Inclusion:

How does it work, what is it used for?

TerraFlex™ is elasticized through a mechanical process that creates an anisotropic elasticization along a sensitive axis. In the micro mechanics domain, the cellular structure is changed from a spherical shape into an ellipsoid, which accounts for the increased flexibility.

It is used in applications that can benefit from a material that will undergo "controlled yielding." For example, an earthen retaining wall will experience lower lateral pressures due to the controlled yielding of a layer of TerraFlex™ placing the earth in it's active state, mobilizing it's internal strength.

Integral Bridge Abutments built with an elastic layer of TerraFlex™ have a compressible volume that can accommodate the motion of the abutment into the embankment as the bridge deck heats and cools with the seasons.

How is it installed?

TerraFlex™ is made into sheets measuring 4 feet x 4 feet x Thickness (varying from 2" to 30"). These sheets are usually installed between the structure and the soil, with a putty like adhesive used to hold the sheets against the structure until backfilling takes place. In soil arching applications, the TerraFlex™ can be cut into more narrow strips and placed over the buried conduit or pipeline as the compressible inclusion (See the paper on Soil Arching for more details)
