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.

PC Leakinject Hydrogel 6880 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, PC Leakinject Hydrogel 6880 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 through 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

  • Concrete
  • Masonry
  • Mortar
