Reinforced repointing is a particularly effective solution for improving the structural behavior of historic masonry façades, as it provides distributed confinement and better connection between masonry units, resulting in significant increases in shear and compressive strength and a marked improvement in ductility.
Its effectiveness is even more evident in typical historic constructions, often characterized by multi-leaf masonry with poor interlocking, low-quality mortars, and the need to preserve the original appearance of the façade—conditions that limit the use of invasive or visible strengthening techniques.
Compatibility with NHL lime mortars and natural materials, together with the reversibility and near invisibility of the intervention, allows the system to be used on protected masonry and façades, ensuring effective strengthening with minimal aesthetic impact and full respect for conservation requirements.
RETICOLA is the Fibre Net system for strengthening fair-faced masonry through reinforced repointing of joints.
The intervention consists of inserting stainless steel strands and connectors within the mortar joints, integrated into the new repointing, with the aim of improving the mechanical performance of the masonry without altering its architectural character.
In Building Construction
In the building sector, RETICOLA is particularly suitable for the restoration and improvement of historic buildings and exposed residential masonry, where the strengthening must integrate seamlessly into the structure without modifying its architectural language.

This technique is also applied in the strengthening of masonry bridges and tunnels, contributing to distributed resistance of the masonry surface and ensuring adequate durability even under demanding service conditions.

Reticola
The RETICOLA system, based on the Reticolatus™ technique, consists of carrying out reinforced repointing of the mortar joints between stone or brick units forming the masonry, through the use of special stainless steel strands and connectors, specifically designed and dimensioned for this application.
Reticola Twin
The RETICOLA TWIN system consists of reinforced repointing of the joints on both faces of the masonry panel, using stainless steel strands and connectors inserted within the mortar joints.
The resulting three-dimensional reinforcement improves the masonry’s resistance to shear, bending, and compression, while preserving its original aesthetic appearance.
Reticola Plus
The RETICOLA PLUS system is a further development of the RETICOLA system and consists of reinforced repointing of the joints on the façade to be left exposed, combined with the application of reinforced plaster using preformed GFRP meshes on the opposite side to be rendered.
The resulting three-dimensional reinforcement improves the masonry’s resistance to shear, bending, and compression, while preserving its aesthetic appearance.
The system can be removed without altering the existing masonry. It enables non-invasive interventions compatible with historic buildings.
It ensures high structural performance thanks to the three-dimensional reinforcement network. It improves load-bearing capacity and stress distribution.
It can be used in combination with different types of mortars and substrates. It integrates easily into both rehabilitation and new construction works.
The system is non-invasive and easily concealed. It allows the original appearance of the surfaces to be preserved.
Installation is fast due to the lightweight and ease of handling of the components. It reduces execution time and on-site costs.
It does not alter the vapor permeability of the structures. It preserves the natural hygrometric behavior of the masonry.
