PFC-350 Hydrophilic Flexible PU Injection Grout

PFC-350 — Water-Reactive PU Injection Grout

PFC-350 is a high-performance single-component polyurethane chemical injection grout for waterproofing by injection. Reacts with water to expand and foam, effectively sealing cracks, honeycombs and window frame joints in concrete.

Features

• High tensile strength and adhesion
• Waterproof, elastic, tough
• Fast expansion on contact with water
• Chloride-free — no rebar corrosion
• Minimal shrinkage after expansion

Applications

• Concrete crack injection
• Honeycomb filling
• Window frame joint sealing
• Building walls, tunnels, dams

PFC-350 vs PFC-250

PFC-350 reacts faster with higher expansion — best for quick sealing. PFC-250 reacts slower for deeper penetration into longer cracks.
