Miscellaneous Aspects of Geomembranes. Seams.... Vulcanizing tapes and adhesives are used on a very dense thermoset materials such as butyl and EPDM [ethylene-propylene-diene-monomer] . Here an uncured tape or adhesive containing the polymer base of the geomembrane and cross-linking agents are placed between the two sheets. Upon application of heat and pressure, cross-linking occurs, which gives the necessary bond. Factory seams are made in large vulcanising presses or autoclaves, while field seams require a portable machine to provide the necessary heat and pressure.
