Parex LA Repair Concrete

Class R4, Flowable, High Strength, Deep Fill, Low Resistivity Cementitious Micro-Concrete

Parex LA Repair Concrete is a cement based, low alkali, one-component, high strength, deep fill micro-concrete with non-shrink properties. The mixed mortar produces a flowable repair mortar suitable for pouring applications meeting the requirements of Class R4 of EN 1504-3. Due to low resistivity, the Product can be used with cathodic protection systems. 

  • One-component, ready to use.
  • Easy to mix and apply. 
  • Good early compressive strength (~20 N/mm2 at 1 day). 
  • High final compressive strength (~80 N/mm2 at 28 days). 
  • Non-shrink (in both plastic and hardened states). 
  • Repair depths up to 500mm in one application.
  • Self-compacting (vibration not required). 
  • Uses aggregates which are not susceptible to Alkali-Silica Reaction (ASR). 
  • High tensile adhesion / bond strength negating the need for a bonding primer. 
  • Suitable for use in conjunction with cathodic protection (low resistivity). 
  • Low chloride content enabling it to be used in contact with steel. 
  • Can be placed under gravity or pumped.  
  • Reaction to fire: EuroClass A1.
