Description

Renderoc LA is a single component, free-flowing low alkali micro-concrete.

The highly fluid nature of Renderoc LA obviates the need for compaction and vibration even where access to the repair zone is restricted or where reinforcement is congested.

It is ideal for the reinstatement of large, structural sections of concrete as well as for many smaller locations where difficulties of access make hand or trowel applied mortars impractical.

Features:

  • Contains no chloride admixtures.
  • Dual expansion system compensates for shrinkage in the plastic and hardened states.
  • Exceptional bond to the concrete substrate without independent primer.
  • Self-compacting nature eliminates honeycombing and displaces air without vibration.
  • Suitable for placement by pumping or pouring techniques into restricted locations.
