For the purposes of draining material deposited in the tailings pond under construction, there was aneed to examine the properties of the high-density polyethylene drain tubes and the consistingmaterials in order to assess their adequacy in the specific conditions. The conducted laboratoryinvestigations of the samples cut from the tubes included: determination of bulk density, tensilestrength in the tangential direction, as well as the compressive strength in a radial direction.Representative samples of the tubes themselves were tested in two different loading dispositions, inorder to record the load-deflection effects. The test results indicated the specific behavior of thetested material in service conditions.
