EPDM waterstop WT CONSTRUCTION

copolymerfor civil engineeringjoint

Product overview
Hydro-expansive profile based on AMPHIBIA copolymer in EPDM, reinforced with a steel mesh. Designed to seal construction joints and passage/transition elements; activates on contact with water to form a watertight seal.

Benefits

• Versatile: adapts to wet, rough, uneven, sloping, vaulted or ceiling supports; operational from -15°C to +50°C
• Quick and easy application: installed by nailing
• Strong mechanical anchoring: stable during concrete casting and impact-resistant
• Progressive adhesion: adheres to the substrate during casting; adhesion increases as the material expands on contact with water

Areas of application

• Construction joints
• Transition and passage elements
