Newton 320-FP Injection Resin

A foaming polyurethane injection resin that reacts with water to form a rigid, hydrophobic seal against water ingress. The resin reacts quickly with water and expands to produce an open-cell, rigid foam that is ideal for stemming water ingress at defects in concrete structures and steel piled walls.

Newton 320-FP is a two-part product with a low viscosity and a fast reaction time with water, making it perfect for Stage 1 stemming of leaks, even where there is a high flow of water or significant levels of hydrostatic pressure. Newton 322-SP or Newton 323-SA can then be used to fully seal the defect.

In contact with water, Newton 320-FP creates high volumes of carbon dioxide that rapidly expands the resin to produce an open-cell, rigid foam that stems water ingress at joints, cracks, voids and defects within concrete structures, as well as sealing water leaks through steel piled walls.

    Key Benefits

    • Forms a hard, high-strength seal within the structural crack or joint.
    • Penetrates deep into fine structural cracks.
    • Has a minimum free expansion of 1,700% – 2,200%.
    • Does not shrink after curing.
    • The reaction speed can be controlled by adjusting the amount of catalyst that is used.
    • Chemically resistant against water, weak acids and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products.
