A four-part acrylic injection resin with a controllable reaction time and low viscosity, making it ideal for sealing fine cracks, wet or dry, deep into the substrate. The resin can also be injected into the HydroTank 302 InjectionHose system to provide a maintainable Type B waterproofing solution.

PC 509 Z Acryl is a four-part injection resin with a very low viscosity, and high adhesion and flexibility, making it ideal for sealing extremely fine cracks deep within the substrate, even where future movement is expected. It can also be injected into the HydroTank 302 Injection Hose waterbar, for sealing the construction joints of new concrete structures and creating a maintainable 'Type B' structure.

Specialist resin injection contractors can adjust the mixing ratios of the four components to adjust the reaction speed of PC 509 Z Acryl from a few seconds to several minutes. The cured resin also has excellent chemical resistance, and will swell in contact with water, retaining that moisture so as not to dry or shrink even under seasonal temperature and water level fluctuations. The product is therefore ideal for injecting into the ground in curtain injection scenarios.

Key Benefits

  • Penetrates very deep into fine cracks
  • Swells in contact with water and retains that moisture even at high temperatures
  • Slow reaction times and very long working life
  • Suitable for use within injection hose systems such as Newton 302 Injection Hose

Typical Waterproofing Applications

  • Deep sealing of wet or dry joints and fine cracks
  • Stage 2 sealing to complete the water sealing operation after Stage 1 has been carried out by products such as PC Leakinject UNI 6816 E
  • Post-construction sealing of construction joints within reinforced concrete structures via the HydroTank 302 Injection Hose system
  • Ground/curtain injection

Suitable Substrates

  • Concrete
  • Masonry
  • Steel
