Newton 321-FSP Injection Resin
A single component polyurethane injection resin that provides a flexible seal in voids and non-structural cracks, or reacts with water to form a flexible, closed-cell foam. The resin is able to seal both pressurised and non-pressurised leaks, whilst its flexibility makes it ideal for applications where movement is expected.
Packaging (Resin): 25kg container
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.
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.
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
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.
