    Choosing The Right Injection Resin

    Newton's resin injection comparison matrix provides an overview of all of the resins within the Newton ReSeal System for sealing and preventing water leaks.

    Resin Injection Matrix

  • Newton 321-FSP is a single-component injection resin that rapidly reacts in contact with water to form a dense, closed-cell polyurethane foam that expands to fill the crack or void. Alternatively, in dry situations Newton 321-FSP penetrates deep into the defect and cures to provide a flexible seal.

    The flexibility of the cured product makes it ideal for cracks and joints where future movement is expected, however the product is applicable in a range of both pressurised and non-pressurised scenarios, including leaks, cracks and voids in the walls and floors of concrete and masonry structures, tunnels, and sewer pipes.

    Key Benefits

    Absorbs movement within the crack or joint

    Penetrates deep into fine cracks

    Does not require an additional catalyst where water is present

    Exhibits high levels of chemical resistance

    Good adhesion to mineral construction materials such as concrete, masonry and mortar

    Typical Waterproofing Applications

    Stage 1 stemming of water-flow thorough joints, cracks, voids and defects within concrete structures and steel piled walls

    Stage 2 sealing of dry, cracks voids and defects after Stage 1 has been carried out

    Suitable Substrates




    Newton ReSeal System

    The Newton ReSeal System consists of a range of Newton's advanced concrete repair mortars and injection resins to seal structural and non-structural cracks and defects, whether they are dry or leaking large volumes of water.

    The products in the Newton ReSeal System can be used to repair a number of defects, including spalled and broken concrete to walls and pillars, road repairs, and cracks and honeycombing to concrete basement walls, soffits and floors.
