Single Component Semi-Flexible Polyurethane Grout
NeXTeRA2441 is a single-component, hydrophobic polyurethane system developed by Geo Constech, formulated using MDI and polyether polyols. Engineered with an inbuilt active accelerator, NeXTeRA2441 reacts only upon contact with water, rapidly forming a non-toxic, semi-flexible polyurethane foam. This advanced formulation is ideal for applications requiring controlled expansion and durable waterproofing performance.
