I am going to attempt to use a sheet of HDPE betwen a concrete footing and the base of a column to allow the column to move with thermal expansion in the structure it is supporting. My question is how can I determine if the HDPE will be crushed by the weight of the column and no longer act as a "bearing". The pressure from the column will be ~140 psi, and the tensile strength of HDPE is 4,000 psi with a Rockwell hardness of [Shore D60-68]. If this material is not strong enough what would be a suitable alternative?
