PC-Inject Seal® PU 300

Flexible Polyurethane Injection Foam for Permanent Water Leakage Prevention

PC-inject Seal® PU 300 is a two-component Polyurethane injection resin with low viscosity designed for grouting and sealing cracks and fissures that hold water in concrete and brick structures. This solvent-free resin initiates a chemical reaction upon the mixture of both components, transforming into a flexible and elastic gel. When in contact with water, the resin expands, effectively creating a flexible seal. For optimal results, it is advisable to combine PC-inject Seal® PU 300 with PC-inject Seal® PU 200 to effectively stop water flow.

FEATURES

  • Excellent adhesion to dry and wet substrate.
  • Remains flexible at extremely low temperatures.
  • Cured resin remains stable and does not shrink over time.
  • Cured gel is chemically inert and nonhazardous to environment.
  • Resistant to high hydrostatic pressure and forms a permanent seal.
  • Cured gel is non-toxic and can be used in contact with potable water.
  • Extremely low Viscosity.
  • Ability to penetrate fine cracks under pressure.
  • The hardened gel/foam remains flexible. Can accommodate movement in concrete.
  • Forms a permanent seal which is highly elastic and flexible. Can accommodate movements in concrete.
  • Form a hydrophobic foam when it meets water in the cracks or fissures to force the water out from the structure.

USES

PC-inject Seal® PU 300 is meticulously developed to establish a durable and flexible seal within waterbearing cracks and fissures present in concrete, block work, and brickwork. This formulation is adept at sealing dry cracks and joints in concrete that are susceptible to shifting. Moreover, it proves efficient in injecting non-re-injectable hoses commonly utilized in concrete joints.
