ARDEX WPM 1955 is a hydrophilic, swelling, polymeric rubber joint for use in areas of brakish, saline or briny salt water. Due to its particular chemical composition, ARDEX WPM 1955 hydrophilic rubber joint remains unaltered over time even at maximum expansion. It is dimensionally stable even after numerous hydration and dehydration cycles while maintaining its ability to increase its volume.
At maximum expansion, in all its sections, ARDEX WPM 1955 is mechanically strong and elastic. The swelling process is controlled and designed to be compatible with fresh concrete.
