Description

Renderoc LA55 is a single component, free-flowing low alkali micro-concrete.

The highly fluid nature of Renderoc LA55 obviates the need for compaction and vibration even where access to the repair zone is restricted or where reinforcement is congested.

Renderoc LA55 is designed for the reinstatement of large, structural sections of concrete and for smaller locations where difficulties of access make hand or trowel applied mortars impractical.

Renderoc LA55 is suitable for use where excellent chloride and carbon dioxide resistance is required or for repairs to concrete affected by alkali-silica reaction. Renderoc LA55 is alkaline in nature and will protect embedded steel reinforcement. The resistivity of Renderoc LA55 makes it suitable for electro-chemical repairs.
