Polyurethane Injection Resin (DryTex INSTA 501)

DryTex INSTA 501 is a high-performance polyurethane injection resin specifically designed for the instant stopping of pressurized water. This polyurethane injection resin rapidly reacts upon contact with water, forming a foam that effectively blocks water flow and seals cracks and construction joints permanently and elastically. INSTA 501 is solvent-free and highly resistant to hydrolysis, making it an ideal solution for water-stopping in various applications. The fast-reacting, semi-rigid PU foam provided by this polyurethane injection resin is perfect for sealing leakages and stopping active water leaks with high flow or high hydrostatic pressure, ensuring reliable instant water stops in structures that experience movement.

• Forms a permanent sealing with high strength in the crack or joint.
• Easy application and seamless
• Single injection sealing of water-bearing cracks and joints
• Highly Flexible to accommodate differential movements
• Penetrates deep in fine cracks and withstands water pressure
• Non-toxic when contacted with drinking water.
• High-density and elasticity foam with excellent waterproof properties.
• Excellent adhesion to mineral construction materials
• Superior adhesion to dry and wet substrates.
• Compatible with concrete, steel, masonry mortar, GRC and various substrates
• It is chemically resistant to water, salts, acids and alkali, mineral oils, fungi and bacteria,
• Suitable for Groundwater, seawater, and petroleum products.
• Comply with NSF/ANSI 61-5 std for potable water and resistant to biological attack.

Our polyurethane injection resin excels in sealing water-bearing cracks across a range of critical structures, including building sub-structures, reservoirs, dams, tunnels, bridges, and manholes. It is particularly effective for basement waterproofing, void filling, and back grouting. Whether for new construction projects or the repair and maintenance of existing structures, this resin ensures reliable and long-lasting results. Its advanced formulation offers superior performance in challenging conditions, making it a versatile choice for various construction and repair needs.
