P+Ex, the Center of Excellence for Concrete Preservation and Service Life Extension, has announced a strategic partnership with the Post-Tensioning Institute (PTI) aimed at advancing sustainability, durability, and resilience in the built environment.The collaboration brings together P+Ex’s expertise in concrete preservation, repair, and service life extension with PTI’s global leadership in post-tensioning technology. Through this alliance, the two organisations will work to advance best practices in durability-focused design for new structures, while also promoting effective repair, rehabilitation, and life extension strategies for existing infrastructure.According to the partners, the initiative is designed to reduce the environmental impact of construction by extending the service life of concrete structures and improving their long-term performance. The collaboration will focus on knowledge-sharing, joint initiatives, training programmes, and broader industry outreach to encourage sustainable approaches across the construction and infrastructure sectors.Commenting on the partnership, Peter Emmons, P+Ex, said, “We are excited to have PTI join us on the P+Ex journey and look forward to working together to create progress toward our shared values. Extending the life of our planet is a worthy cause and we are moving in a great direction with organizations such as PTI joining the effort.”Tim Christle, Executive Vice President, Post-Tensioning Institute, said the affiliation brings together complementary strengths. “The P+Ex and PTI affiliation brings together distinct strengths. Together, we are taking another step toward ensuring that post-tensioned concrete structures emphasize durability, resilience, and sustainability, leveraging the extended service life benefits of post-tensioning,” he noted.Through the partnership, P+Ex and PTI aim to champion innovative and sustainable solutions for both new post-tensioned construction and the repair of ageing structures. By aligning their missions, the organisations said they are taking a significant step toward enhancing the sustainability, safety, and long-term performance of critical infrastructure worldwide.
