DRACO PVC WATERSTOPS are very elastic waterproof profiles that should be used for cold joints, expansion joints and concrete buildings to ensure complete water-tightness while providing resistance to mechanical and natural stress. DRACO PVC WATERSTOPS consist of top quality thermoplastic vinyl resins. They are very resistant to aggressive acid alkaline solutions, age-related wear and brackish water. They are resistant to deterioration caused by exposure to sunlight, ozone and other environmental or chemical agents normally present in the air or in groundwater. They are highly flexible even at low temperatures and their mechanical properties do not change over time.
