Parex Epoxy Thixotropic Injection Grout

Epoxy Thixotropic Injection Grout is a Thixotropic Two-Part Epoxy Resin System
  • Thixotropic.
  • Can be placed without the need for grout tight shuttering. 
  • High mechanical strength.
  • Good adhesion to most construction materials (i.e. concrete, masonry, stone, steel, wood, etc.).
  • Easy to use.
  • Can be placed with a suitable hand or mechanical pump.
  • Suitable for grouting and sealing the narrowest of gaps (as thin as 0.1mm).
  • Can be used to fill cracks, fissures and voids up to 10mm.
  • Non-shrink.
  • Application temperature range +5°C to +30°C.
  • High early strength gain.
  • Hardened grout is resistant to most chemicals, sea water and petroleum products.
  • Can provide structural support where dynamic load resistance is required.
  • Can be used to fill and bond cracked concrete.
  • Hardened grout resists freeze-thaw cycles.
  • Solvent free.
  • Available in a convenient 1.191kg size.

Parex Highway Rapidpave Cement

Ultra-Rapid Strength Gain Binder
  • Binder used in place of Ordinary Portland Cement to produce a rapid setting concrete.
  • All mixing water is completely chemically bound, resulting in no water surplus. The water surplus that occurs with other cement types is the cause of shrinkage, cracking and warping.
  • Non-shrink when used in well-designed concrete.
  • High freeze-thaw resistance.
  • Not based on Ordinary Portland Cement.
  • Higher water demand than concrete with Ordinary Portland Cement which results in an improved yield.
  • Quick setting.
  • Ultra-rapid strength gain (compressive strength of 35N/mm² achievable at only 4 hours).
  • High ultimate strength.
  • Rapid return to service.
  • Suitable for marine or tidal zones.
  • Can be delivered and placed in remote locations.
  • Does not require a concrete plant to produce concrete.
  • No risks of concrete hardening in transit or being unsuitable at the time of placing.
  • Exact amount of concrete produced, zero waste.
  • No specialist tools or training required for the contractor.
  • Consistent quality, unlike Pavement Quality Concrete which can vary from load to load.
  • Reduced CO2 emissions. Specialist cement used is considered a green binder because of the following factors:
    • This cement is calcined at 1250°C (2250°F), whereas Ordinary Portland Cement is calcined at a temperature of 1500°C (2700°C).
    • The clinker is much softer compared to Portland clinker, which reduces the energy requirement during grinding.  

Parex LA Repair Concrete

Class R4, Flowable, High Strength, Deep Fill, Low Resistivity Cementitious Micro-Concrete
  • One-component, ready to use.
  • Polymer modified for improved adhesion and performance.
