Composite system consolidation solutions
Prevention and safety
Prevention of seismic risk and securing the existing building stock through innovative reinforcement technologies. Certified fiber-reinforced composites are applied by qualified personnel with specific certification. Structural strengthening, seismic improvement, and seismic retrofit of reinforced concrete and masonry buildings are carried out. The company has performed interventions in the areas affected by the seismic events of 2009 (Abruzzo), 2012 (Emilia Romagna), 2016/2017 (central Italy: Lazio, Marche, Umbria, Abruzzo).
How to improve the safety and durability of structures
The main interventions consist of rehabilitation of reinforced concrete structures, Reinforcement of beams and columns using different composite materials, reinforcement in slabs and walls, load-bearing masonry, vaulted elements, anti-deflection system of floors, and anti-overturning of cladding panels.
Structures, such as buildings, bridges, and infrastructure, are exposed to a variety of agents that can compromise their safety and durability. These agents include:
- Natural wear and tear: over time, even the strongest materials undergo a process of degradation, which can lead to a reduction in their load-bearing capacity.
- Natural events: earthquakes, floods and other natural events can severely damage structures.
- Design or construction errors: even a small mistake can have serious consequences for the safety of a structure.
To prevent or mitigate damage to structures, structural consolidation can be performed. Structural consolidation is an intervention that aims to improve the performance of a structure, making it stronger and safer.
Composite system consolidation solutions
One of the most widely used structural consolidation techniques involves the use of composite materials, consisting of two or more components, each with its own characteristics. The fibers, which provide the mechanical strength, are usually made of carbon, glass or aramid. The matrix, which gives the composite material cohesion and abrasion resistance, is usually made of polymer resin.
Composite materials have a number of advantages over traditional materials used for structural reinforcement, such as concrete or steel. In fact, composite materials are:
- Strong and lightweight: composite materials have high mechanical strength, making them ideal for the consolidation of weakened or damaged structures. In addition, their lightness facilitates their installation.
- Ductile and flexible: composite materials are ductile and flexible, making them suitable for structures that must withstand vibration or movement.
- Low maintenance: composite materials are low maintenance, which means they do not require frequent inspection or repair.
Applications of composite system consolidation solutions
Composite system consolidation solutions encompass a wide range of applications, including:
- The strengthening and retrofitting of existing masonry and reinforced concrete structures: composite materials can be used to strengthen beams, columns, floors, and other structural elements made of concrete or masonry.
- The restoration of damaged structures: composite materials can be used to restore the functionality and safety of structures damaged by natural events or by design or construction errors.
- Weather protection: composite materials can be used to protect structures from weather conditions, such as rain, wind, and snow.
Advantages of composite system consolidation solutions
Composite system consolidation solutions offer a number of benefits over other consolidation techniques, including:
- The improvement of structure safety: composite materials give structures greater strength and load-bearing capacity, improving their safety.
- The improvement of the durability of structures: composite materials are low maintenance and resist natural wear and tear, increasing the life of structures.
- It is a versatile solution: composite materials can be used for a wide range of applications, making them a versatile solution for structural strengthening.
List of the main reinforcement technologies
FRP (Fiber Reinforced Polymers)
Systems composed of fiber reinforcement fabrics and polymer matrix of organic nature (epoxy resin). Composite systems used have CVT (Technical Assessment Certificate) issued by the Superior Council of Public Works.
Carbon fiber for structural reinforcement
Consolidation of structural and nonstructural reinforced concrete, masonry and vaulted elements by bonding and impregnation of high-strength carbon fiber fabrics of different weights and weaves.
Composite Reinforced Mortar (CRM) and Fiber-Reinforced Cementitious Matrix (FRCM)
Systems composed of fiber reinforcement meshes and inorganic matrices (lime or cementitious mortar). The FRCM composite systems used have CVT (Technical Assessment Certificate) issued by the Superior Council of Public Works.
Protection of Non-Structural Elements in Buildings Subject to Collapse and Overturning
Protection system from the collapse and overturning of masonry partitions and curtain walls and anti-deflection systems in reinforced concrete floor slabs.
The aim is to reduce the seismic vulnerability of non-structural elements and improve the performance of floors made of hollow core slabs.
Infill wall anti-tilting systems
by applying biaxial natural basalt fiber mesh with pure lime plaster skim coat, then using crack stitching bars.
Reinforcement of cracked hollow-core slabs
by laying fiberglass mesh and a ready-to-use single-component adhesive
