Product Information: Geomechanics and Tunnelling 2/2025

As the demands of modern tunneling projects grow, Protan is leading the way with cutting-edge solutions.The Protan In-fraWeld System is a groundbreaking innovation that simplifies, accelerates, and enhances the installation of waterproof tunnel membranes. A New Standard in Efficiency and QualityInfraWeld eliminates the need for membrane penetration during installation, ensuring unmatched waterproofing integrity.This revolutionary system introduces an induction-based bonding process that offers visual and acoustic quality control, making it a safer, faster, and more efficient choice for contractors.By using electromagnetic induction, In-fraWeld generates heat directly within specially designed plates beneath the membrane, activating a strong, watertight bond without damaging the material.The system even allows for repositioning of the membrane during installation, delivering flexibility without compromising quality. Key Benefits-Fewer Steps, More Efficiency: Significantly reduces installation time and labor.-Unmatched Waterproofing: Membrane remains intact-no penetrations required.-Reduced Material Use: Less waste for a more sustainable process.-Cost Savings: Faster installation reduces project costs and timelines.
