PVC waterstops are ideal for concrete structures, withstanding temperatures from -30°C to +70°C. They provide resistance to ageing, chemical attack and salt and acid solutions, maintaining long-term high performance. Perfect for protection against water in harsh environments and compatible with synthetic PVC membranes. Waterstop “4TV” profiles are used for waterproofing in concrete casting in outdoor laying and ensure watertightness even under pressure. They are used both to contain water in the construction of swimming pools, canals, aqueducts reservoirs and dams, for example, and for water protection in foundations such as in tunnels and silos. The type of PVC employed allows waterstops to be used on concrete structures exposed to temperatures between -30°C and +70°C, ensuring considerable resistance to ageing, chemical aggression in alkaline environments brackish water and acid solutions.
