Protex PolyLock is an advanced, next-generation waterproofing system specifically engineered to meet the demanding requirements of tunnel waterproofing projects. This innovative system offers exceptional durability and effectiveness by incorporating a unique combination of self-healing, polymer-modified sodium bentonite granules or bentonite powder with a robust impermeable polyethylene (PE) film layer and an active polymer layer. This multilayered design ensures comprehensive and long-lasting protection against water intrusion, even in the most challenging environmental conditions. One of the standout features of Protex PolyLock is its ability to form an active layer that continuously adapts and responds to the structural and environmental changes throughout the life of the tunnel. This active layer enhances the system’s self-healing properties, ensuring that minor cracks or punctures are automatically sealed, providing a reliable waterproofing solution without requiring additional maintenance. Protex PolyLock is not only designed to withstand the high pressure and dynamic forces commonly encountered in tunnel construction but also delivers excellent resistance to chemical exposure, making it a versatile solution for various types of underground projects. Its seamless integration into the construction process allows for efficient installation, reducing time and labor costs while ensuring superior performance. This cutting-edge waterproofing system has been extensively tested and proven effective in maintaining structural integrity in tunnels, subways, and other underground infrastructure. Its advanced technology and innovative design make Protex PolyLock a preferred choice for engineers and contractors aiming for long-term reliability, safety, and peace of mind.
