Polyurethane Injection Resin (DryTex INSTA 501)

Water leakage through cracks can compromise a structure’s stability, durability, and safety, leading to serious long-term damage. DryTex INSTA 501 is a high-performance Polyurethane Injection Resin designed for instant water stoppage in pressurized environments. This advanced resin reacts rapidly upon contact with water, forming a durable PU foam that effectively seals cracks, construction joints, and active leaks.

This solvent-free Polyurethane Injection Resin penetrates deep into cracks, expanding and curing into a semi-rigid or gel-like barrier based on site conditions. Engineered to withstand high hydrostatic pressure, it ensures long-term water sealing, even in underground structures, tunnels, basements, and foundations.

Whether you’re sealing active leaks or preventing future water ingress, DryTex INSTA 501 delivers a lasting, high-performance waterproofing solution. Contact us today to learn more!
