Waterstop RG profiles are used for waterproofing purposes for connecting concrete casting and are watertight even under pressure. They are used to contain water when making, for instance, swimming pools, ducts, waterworks, reservoirs and dams, and to insulate foundations such as tunnels and silos for water. The kind of PVC used means the waterstop can be used on concrete structures exposed to temperatures between -30°C and +70°C. This ensures noticeable resistance to ageing,chemical attacks in alkaline environments, brackish water and acid solutions. They are resistant to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the air and groundwater. They have high flexibility even at lowtemperatures. Mechanical characteristics remain unchanged over time.
