Helix steel aisi Helical bar in AISI 304 stainless steel, cold drawn, with high mechanical performance, for the reinforced styling of joints and for connections, including through-holes, on masonry, reinforced concrete, arches and vaults. Suitable for the consolidation of structures in seismic areas; advantageous in combination with hydraulic binders (cement and hydraulic lime) and with resin matrix binders, it particularly facilitates the achievement of physical and mechanical performances in combination with Unisan mortar, with those of the REPAR, GROUT family and with the structural resins of the SYNTECH family. The optional accessory Connector Steel Aisi 304, supplied separately on request, allows the connection between the passing helical bar and the helical bar positioned deeply on the stripped joint. Helix Steel AISI 304 bars are available in a range of diameters: 6, 8, 10 or 12 mm, all characterised by their durability even in aggressive environments, their high tensile and shear strength, and excellent flexibility. Such characteristics make the use of these bars particularly advantageous in combination with hydraulic binders (cement, hydraulic lime), air binders (air lime) and resinous matrix binders. Flexibility, handling and versatility with various binder matrices, permit the realisation of rapid, non-invasive reinforcement operations, being easy to apply and with low installation costs. Very high mechanical physical benefits come when combined with our mortars of the REPAR, GROUT and Unisan lines and the structural resins of the SYNTECH line. Reinforcement operations on concrete and masonry structures. Reinforced pointing of joints. Structural one-sided connections or through-holes crossing the entire section. Helical morphology allows optimal gripping on bricks, mortars, stones and on old walls of historical and cultural interest generally. The durability against atmospheric and environmental conditioning makes the use of Helix Steel AISI 304 bars particularly advantageous in the structures affected by the presence of aggressive soluble salts (sulphates, nitrates, phosphates). Reinforced pointing of joints: Deep stripping of joints can ensure the placement of the bar at a depth of a few centimetres from the surface. To remove any loose and crumbly parts (stone, bricks, enticing mortar, etc.). Cleaning and saturation of the substrate with pressure washing. To remove any saline efflorescence by brushing or sandblasting. Connections on masonry, concrete, arches and vaults: Make sure that there are no loose or crumbly parts on the substrate. Stripping of mortar joints. Cleaning and saturation of the substrate with pressure washing. To remove any saline efflorescence by brushing or sandblasting. Reinforced pointing of joints: Reinforced pointing of masonry joints by filling part of the joint profile with an initial layer of Unisan fibre-reinforced composite mortar (see the data sheet), then on the mortar whilst still wet, inserting the Helix Steel AISI 304 bar before covering with a final layer of Unisan mortar. Press the mortar inside the joint, being sure to press well until totally full and flush with the wall. The temperature of the substrate must be between +5° and +35° C. Connections on masonry, concrete, arches and vaults: After carefully preparing the substrate and before applying the first layer of structural mortar (lime- or cement-based depending on the type of operation), wet with water at low pressure until complete saturation, bearing in mind that a lack of saturation may prevent adhesion and cause cracking in the mortar. If necessary, apply a rough coat of Untersana mortar. Proceed with creating holes of a suitable diameter and inclination (at 45° if the operation is undertaken only on one side of the structural element). Before they are bent in anticipation of the mesh, the connectors emerge from the substrate by at least 10–15 centimetres from flush with the wall. Apply an initial coat of Unisan fibre-reinforced composite mortar (see the technical data sheet) by hand (with stainless steel trowel or putty knife) or with a plastering machine to achieve a thickness of about 1.5 centimetres, leaving the surface sufficiently rough to facilitate the adhesion of the subsequent layer. Alternatively, depending on the structural requirements, mortars of the REPAR line can be used. Place the primed alkaline-resistant fibreglass mesh of the ARMAGLASS STUCTURA line (see the technical data sheet of the selected product), placing it on the still-fresh mortar by passing the Helix Steel AISI 304 connector between the bars of the mesh. After bending the connector, restraining the mesh, apply a second finishing layer of mortar (Unisan or REPAR) at a thickness of about 1.5 centimetres. Product to be purchased as needed.

Rinfor Grout Col is a special cementitious formulation, being fibre-reinforced with READYMESH technology, enriched with reactive microsilicates with very high pozzolanic activity and special crystalliser additives that increase the end result and the durability. Mixed with water, it is able to forge micro-concretes with pourable rheology. Once hardened, the product offers exceptional physical-mechanical and ductility values. Ideal for the reinforcement and seismic adaptation of flooring in reinforced concrete, brick-concrete or corrugated sheeting or wood, by constructing a thin extradoxal structural screed along with beams, pillars, structural crosspoints and walls, by means of suitable liners. The rheological and physical-mechanical characteristics of the Rinfor Grout Col product render it extraordinarily effective in reinforcing structural elements in reinforced concrete and masonry. Adhered to the inside of caissons, confined within cavities or spread out over the extrados of foundations and lofts, Rinfor Grout Col allows for low thickness structural reinforcing, substantially devoid of additional metallic reinforcement. Rinfor Grout Col belongs to the HPFRC (High Performance Fibre Reinforced Concrete) family, permitting the structural designer to make use of the following characteristics: - Exceptional resistance and traction as well as exceptional values of shear stress adhesion on various supports which have been suitably roughened; - advantages in structural calculations prescribed for fracture mechanics, resistance to traction and of the ultimate material deformation; - minimum thicknesses applied with reinforcing effects which have been distinctly improved as against interventions with traditional reinforced concrete; - highly notable reduction of mass and minimizing of additional loads applied for structural reinforcing as against interventions with traditional reinforced concrete (practically nil additional loads in the case of the thickness of the coating corresponding with the depth of sacrificed surface); - anti-carbonatation barrier (practically zero penetration of CO2) and anti-oxidant barrier; - auto-healing of any micro-fissures exposed to contact with fluids, thanks to the particular crystallising additives; - increment of durability of the structures repaired with Rinfor Grout Col, thanks to the migration effect of the crystallising additives; - very high resistance to fire; - eco-sustainability - made up of 100% mineral and metallic materials, totally recyclable at end of life. From the environmental point of view, the Rinfor Grout Col product is characterised by the following advantages: - Ecological packaging (card-cardboard) - product based on hydraulic binders, selected aggregates and mineral additives with content of organic raw materials < 1% - practically nil VOC emissions during installation; once hardened, nil VOC emissions. - containing a fraction > 5% of sub-products from the production industry 100% recyclable at end of life. For seismic adaptation with absorption and transfer of pressure or traction during events with elevated dynamic forces (seismic, impacts, deflagration); - for structural reinforcing and seismic upgrading through coating of beams, pillars structural ties, walls; - for reinforcing and seismic upgrading with external, low thickness, structural screed for lofts in reinforced concrete, concrete masonry, corrugated sheeting, wood;
 - for fabrication of light, thin section, structural elements
; - for the repair of flooring with need for resistance against elevated static and dynamic stresses, together with exceptional values of resilience and resistance to impacts; - for reinforcing and precision anchoring of heavy and highly stressed machinery: E.g. wind turbines, turbines, precision machinery, etc. The support must be in good condition, clean, sufficiently coarse, without crumbling parts or dust, pressure washed and saturated with water before application. With concrete, the abrasiveness of the support must be > 3mm; to obtain this level of coarseness, techniques of hydro-scarifying, bush-hammering, mechanical chiselling, sand blasting with large grain may be considered. With the case of surfaces in strongly absorbent brick-work (lofts in brick cement with surfacing of parts in brick) or in the case in which it is impossible to saturate the support with water, contact our technical services to evaluate suitable adhesion primers, such as Syntech Pavisheer or Syntech RGS. Above all, when used as a surface covering of lofts in concrete, or as a repair to industrial flooring, providing anchoring roots by drilling the support is particularly useful for increasing resistance to cuts and adhesion to the support (diameter 18-20 mm, depth 20 mm), and accurately cleaning the surfaces of the holes before spreading the Rinfor Grout Col.
