MAPEGROUT HI-FLOW ZERO

Fibre-reinforced compensated-shrinkage mortar for repairing concrete

MAPEGROUT HI-FLOW ZERO is a pre-blended mortar in powder form made from high-strength cement, selected aggregates, special additives and synthetic fibres according to a formula developed in the MAPEI R&D laboratories.

Suitable for repairing structures where particular thicknesses or conformations of degraded concrete need to be reintegrated with hi-flow mortar and for anchoring machinery or metal structures accurately in position.

Thanks to its particular formulation the product has excellent fatigue behaviour up to at least 300,000 cycles, which gives repaired structures a high level of resistance to cracking, including when subjected to dynamic loads induced under normal service conditions.

This particular characteristic, together with the requirements of EN 1504, helps increase the durability of elements repaired with MAPEGROUT HI-FLOW ZERO.

MAPEGROUT HI-FLOW ZERO complies with the principles defined in EN 1504-9 (“Products and systems for repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements of both EN 1504-3 (“Structural and non-structural repairs”) for R4-class structural mortars and EN 1504-6 (“Anchoring of reinforcing steel bar”).

Mapei Research & Development laboratories work intensely on product formulations in order to reduce CO₂ emissions associated with our products.

Info CO₂ Fully Offset

*MAPEGROUT HI-FLOW ZERO is part of the CO₂ Fully Offset in the Entire Life Cycle line of products. CO₂ emissions measured throughout the life cycle of products from the Zero line in 2025 using Life Cycle Assessment (LCA) methodology, verified and certified with EPDs, have been offset through the acquisition of certified carbon credits in support of forestry protection projects. A commitment to the planet, to people and to biodiversity.
