Micro-Concrete
A flowable, shrinkage-compensated cementitious repair material with fine aggregate, poured into formwork to reinstate a concrete section.
On an actual building
Where a repair is too deep or too congested with reinforcement for hand-applied mortar, micro-concrete flows around the bars and fills the section completely.
What we most often have to correct
That it is the same as repair mortar. Mortar is hand-applied in lifts; micro-concrete is poured and needs formwork.
