Plantop HPC Floor header

Ultra high strength. Shrinkage-compensated. Highly fluid. Certified for R4-class structural mortars.

The traditional floor slab calls for having tools such as steel connectors and electro-welded mesh. With Mapei's revolutionary product, Planitop HPC Floor, concrete repair and strengthening floor slabs is now made easy without the need for these tools yet, at the same time, able to obtain high strength and fast solution. 

Planitop HPC Floor is a one-component, ultra high strength, highly ductile, highly fluid, fibre-reinforced, compensated shrinkage cementitious mortar for strengthening the external face of floor slabs.

Why choose Planitop HPC Floor

Planitop HPC Floor comparison


When Planitop HPC Floor is mixed with water, it forms a fluid mortar suitable for casting into formwork in layers from 1 to 4 cm thick without segregating, and without the need for electro-welded reinforcing mesh.


To allow expansion in the open air, Mapecure SRA may be added, a special admixture which has the capacity to reduce plastic and hydraulic shrinkage that ensures better curing of mortar. The admixture can reduce the water evaporation and encourages the development of the hydration process. Mapecure SRA acts as an internal curing agent which reduces final shrinkage by 20% - 50%, which means lower risk of cracking.
