The impact of corrosion on the safety of reinforced concrete infrastructure

The problem of corrosion of reinforced concrete infrastructures is deeply felt and European and international regulations governing the methods of assessing the state of deterioration and interventions for the safety of infrastructures are increasing.

The corrosion phenomenon of reinforced concrete starts from the reinforcement and progresses to the concrete, undermining the resistance of the structure to the point of compromising its safety.
Corrosion is due to various contributing causes:
- physical causes (temperature changes, freezing / thawing, fire),
- mechanical causes (shocks, explosions, erosion, abrasion),
- structural causes (settlements, overloads, cyclic loads),
- chemical and electrochemical causes (acids, chlorides, carbonates, internal galvanic currents),
- biological causes (fouling, algae, lichen).
Inspection activities with the assessment of the degree of deterioration are carried out periodically, as well as maintenance, which must include the use of innovative materials and reinforcement procedures that guarantee the durability and safety of the infrastructure.
Depending on the level of degradation reached, we can intervene with different treatments: removal of unstable material, sandblasting, hydro-washing, passivation with alkaline solutions and polymer cement, elimination of cracks with epoxy resins and restoration with technical mortars.
Finally, for the surface protection of the concrete, we perform elastomeric coating treatments (waterproofing, anti-carbonation).

Waterproofing works on the roof of Pavilion B of Gorizia Fair

We will shortly complete the waterproofing works on the roof to stem the micro-cracks and eliminate the infiltration points of rainwater, so as to ensure the conduct of activities inside the pavilion, now an important vaccination center.

Our intervention involves the supply and installation of a combined waterproofing layer made from a layered membrane. Once the membrane is mechanically fixed, a waterproofing layer of "Poliurea Pura Purtop 1000" with a thickness of 2 mm will be applied.

In this way the entire surface of the roof, of about 1,830 square meters, will have a perfectly adherent and resistant waterproofing.
Bad weather it will no longer be a problem for the next vaccination activities planned inside the pavilion.

The application of the paint by means of airless painting allows to obtain a resistant and high quality protective film on the metal surfaces.

At our headquarters in Portogruaro we carry out industrial AIRLESS painting processes. With this processing it is possible to safeguard the environment and protect the operator.

Airless means "free air" spraying: the material is atomized due to the high pressure, comes out of a small nozzle as a fan of very small droplets, so it reaches the surface to be painted at a low speed.

The lack of air and the low speed of paint particles reduce both the bounce of material on the paintwork and the overspray (that part of spray paint that does not deposit). In addition, the amount of sprayed product can reach almost twice as much as other types of paint, and this reduces spraying time.

There are some benefits: a great benefit to the health of the operator, the reduction of the materials to be disposed of and the reduction of the emission into the atmosphere.

Faid Anticorrosione Srl has always focused on the environment: it promotes actions for greater environmental responsibility, development and diffusion of technologies that do not harm the environment. The company is ISO 14001: 2004 certified to continue its commitment to environmental impacts and performance improvement.

PYROCRETE 241: certified application of fire protection

Certification for the application of Pyrocrete 241 hydrocarbon fire protection systems
Flame retardant material for the fire protection of structural steel and to improve the fire resistance of reinforced concrete.

Is a cementitius capillary waterproofing product.
FAID ANTICORROSIONE SRL is certified for the application of PYROCRETE 241 lightened cement plaster and PYROCLAD X1 intumescent epoxy for hydrocarbon fire protection Pool + JetFire.

Service of powder coating

Powder coating of steel, aluminum and metal profiles
The powder coating is an anticorrosive treatment for metal surfaces. The powder coating treatment involves a pre-treatment of the metal surface and a coating for protection against corrosion and aggressive agents.

Faid s.r.l. Has added a new service to its business: the powder coating.

This process is performed by automatic painting facilities that allow high processing capacity.

The powder coating is done on sheets, tubes, and cannelle profiles with a maximum length of 6000 mm gauge and the footprint of 2500 x 2500 mm.

Materials: steel, galvanized metal, including pretreatment.

Procedure for the application of Chartek

Chartek fireproof treatments for passive fire protection of metal structures Chartek is an intumescent flame retardant coating with epoxy reinforcement ad high thickness without solvents.
Chartek is a material that guarantees high performance such as fire resistance and limits the development of a combustion, therefore perfect for the protection of steel and other metal structures.
Suitable for fireproof coatings of industrial structures, partition walls and hydrocarbon tanks, chartek is a protective coating that maintains the integrity of the structure over time.

Works - POLYUREA application

Waterproofing with polyurea of bridges, viaducts, underground structures and tunnels

The Polyurea is a two-component polyurea elastic membrane, with rapidity of hardening in the order of a few minutes and a rapid achievement of the final characteristics.
High mechanical strength, chemical hydrolysis, puncture, abrasion and aging.
Minimum application temperature: 0 ° C (non-condensing). Working temperature from - 30 to +85°C.

The main uses of polyurea are:
- Waterproofing slabs of road and rail bridges, viaducts, underground structures, tunnels;
- Protection and waterproofing of hydraulic structures and containment;
- Waterproofing for roofs of civil and industrial buildings;
- Waterproofing of parking large cars. Protection and encapsulation of asbestos cement.

Works - Polyurethane Hydroexpansive Resin

Waterproofing with hydro-expansive and water-reactive resins to block water infiltration in tunnels and underground rooms

It's an injectable material that fills and seals off cracks, crevices and cavities finally putting an end to infiltration, quickly and decisive.

Is injected through specific hand pumps or electric high-pressure injectors affixed by screw and permeates cracks up to widths of 0.2 mm.

In contact with water or moisture, increases after a few seconds, from 8 to 20 times its initial volume, through a process of reaction with the formation of a dense foam and elastic, which immediately stops the infiltration and hermetically seals the slot or cavity injected.


Waterproofing of concrete with PENETRON
Penetron is a waterproofing system for concrete by crystallization, used for the construction of new underground structures with a waterproof seal.
Penetron waterproofing of existing concrete surfaces ensures protection from the presence of groundwater and hydraulic thrust. Penetron is also resistant to chemical agents present in the subsoil and in the sea, therefore suitable for waterproofing bridges, viaducts and underground piers.
