designer and professional can choose to build using products with zero impact on climate change, high performance, and durability. Research and Development laboratories have worked hard to reduce the carbon footprint to offer quality, sustainable products formulated with recycled materials and developed to reduce energy consumption at very low volatile organic compound (VOC) emissions. Residual CO 2 is offset through the purchase of certified carbon credits to support renewable energy projects and forest protection. The environmental impact of products is calculated using the LCA (Life Cycle Assessment) methodology and is certified and disclosed through the EPDs (Environmental Product Declarations) available on our website. 5. Conclusion Damaged and aged concrete structures, as beams, piles, columns can be restored with a high sustainable approach considering the application of a structural repairing mortar with high fatigue flexural strength, protected with a flexible cementitious membrane able to prevent the ingress of all aggressive agents. Both systems are even fully CO 2 offset, thus restoration cycle ensure an high durability and sustainability level. As detailed above, durability is a fundamental aspect of sustainability: the reduced need of maintenance and restoring actions will generate less energy and time need, and less demolition wastes. Moreover, the high dynamic resistance of the restoring mortar elongates the infrastructure life and its components durability, with evident benefits for all stakeholders: from the owner to the users.
