PC Leakinject UNI 6816 E is a single-component PU resin and catalyst with low viscosity suitable for water-sealing big gaps, cracks, or water leaks with high pressure or flow. Reacts in contact with water to form a semi-rigid foam.

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 1700-2200%

  • 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, groundwater, seawater and petroleum products

Typical applications

Stage 1 stemming of water ingress through joints, non-structural cracks, voids and defects within concrete structures and steel piled walls. 

Suitable substrates

  • Concrete

  • Steel piles
