For floors with voids, the type of repair material depends on the strength class. Non-shrink grout such as Mapefill GP or Mapefill SPis recommended for grouting voids in structural elements such as patching up honeycombs in concrete, filling gaps in precast elements, and grouting base plates and bridge bearings. For repairing and strengthening concrete structures with higher performance, Planitop HPC Floor can be considered.
