Planitop HDM Maxi is used in combination with Mapegrid G 120 and Mapegrid G 220 primed alkali-resistant A.R. glass fibre mesh or Mapegrid B 250 primed alkali-resistant basalt fibre mesh to structurally “reinforce” stone, brick, tuff and mixed masonry structures. The system complies with the approach defined by the guidelines for the approval of FRCM (Fibre Reinforced Cementitious Matrix) systems. Planitop HDM Maxi may be also be used on its own to restore the texture of masonry or to level and even out the surface of reinforced concrete and masonry. Moreover, Planitop HDM Maxi is part of Mapetherm Tile System, for installing tiles and slabs on external wall insulation systems for façades. Some application examples

▪ Cladding facing walls, vaulted ceilings and masonry in general after patching them up.

▪ Used in combination with mesh from the Mapegrid range to increase the shear/tensile strength of bay walls for structures in seismic zones and for structural consolidation.

▪ Used in combination with mesh from the Mapegrid range to structurally strengthen the internal and external face of arched and vaulted masonry elements.

▪ Levelling and repairing reinforced concrete structures.


Planitop HDM Maxi is a two-component, high-strength cement-based mortar with glass fibres, selected aggregates in a granulometric curve, special admixtures and synthetic polymers in water dispersion according to a formula developed in the MAPEI Research Laboratories. When the two components are mixed together (component A powder and component B liquid) they form a plastic-thixotropic mix which may be applied by trowel or spray in layers up to 25 mm thick on horizontal and vertical surfaces. Planitop HDM Maxi has high adhesion strength and when hardened forms a compact layer that is impermeable to water and aggressive gases present in the atmosphere while remaining permeable to water vapour. Planitop HDM Maxi meets the requirements of EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements of EN 1504-3 (“Structural and non-structural repairs”) for R2- class mortars. Furthermore, Planitop HDM Maxi is classified as M25 masonry mortar according to EN 998-2 and as GP render, category CS IV according to EN 998-1.
