Duramortar 530

Duramortar 530 is a ready to use shrinkage controlled concrete for all types of structural repairs. Consisting of a mixture of dry powers and selected aggregates, Duramortar 530 is formulated to produce shrinkage compensated, consistent, fluid concrete, requiring only the addition of potable water on site.


Product uses


  • Can be used for structural repairs requiring high fluidity, e.g. heavily congested steel.
  • As a mass infill repair mortar for structural repairs where there is load bearing.
  • Soffit repairs where heavy load bearing is required.
  • Repairs to restricted access areas, where use of hand applied mortars would prove impractical.
  • Repairs to columns suffering from major loss of section.




  • User friendly – it is ready to use from the bag, suited to local conditions and easy to apply.
  • Economical – if repairs are carried out correctly the first time it is very much more cost effective.
  • Enhanced durability – works in tandem with extremely low permeability to prolong effective service life.
  • Compatibility – modulus of repair medium is compatible to that of host concrete.
