Aymar technical mortars modified with high-quality resins and polymers, controlled retraction, fibro-reforced, allow high initial resistance to flexion and compression. Conceived for important applications where the resulting durability and safety are essential, they show high physiocomecnic characteristics that are resistant to vibration, traction, torsion and shear efforts. Indicated for concrete repairs such as ramps, bridges, horizontal and vertical pavements, they are of excellent fluidity for fillings under anchorage plates, allowing rapid commissioning.
