Repar Tix HG SB Thixotropic, structural, fibre reinforced cement mortar, with compensated shrinkage, with high intrinsic water tightness, and extraordinary physical and mechanical characteristics: adhesion, compression resistance, flexural strength, abrasion resistance, etc. Perfect for remediation of structural works and articles in degraded concrete and very high-performance coatings. Repar Tix HG SB, in addition to normal manual application techniques, it is a structural mortar specially formulated for applications with pumping/spray machines (wet spritz-beton technique). Particularly optimized parameters are: rheology, thixotropy and workability of the product, which allow spraying operations with reduced wear of the mechanical parts and little waste on the ground. Rheoplastic, thixotropic, structural, composite cement mortar, based on special cements and selected siliceous aggregates, reinforced with a balanced mixture of READYMESH polypropylene fibres and calcium metasilicate microfibres, added with specific agents and a high content of silica fume. After hardening, it provides very high performance in terms of intrinsic water tightness, resistance to washing and hydrolysing, mechanical strength, abrasion and cavitation, anti-carbonation, chemical-physical stability, resistance to harsh atmospheric agents and to leaching water. It has three-dimensional fibre-reinforcement, provides high hold; it is dimensionally stable (compensated shrinkage). The product can be supplied in mono-component or two-component version. The product, in the monocomponent version, is mixed with water (approx. 16% of the weight of the bag). In the two-component version, the product is mixed by adding the 4.5 kg of component B. The two-component version increases adhesion to the support and reduces free shrinkage to air, especially in the initial hardening phases and in particularly hot climates, without modifying the physical-mechanical characteristics of the end product. Repairs and protective coatings of hydraulic works (pipelines, dams, tunnels etc.), marine structures and artefacts in critical situations: aggressive chemical-physical agents, leaching water, marine atmosphere, etc. Specific for shotcrete interventions in galleries, tunnels, rock walls, irrigation and hydraulic channels, piles and micropiles, diaphragms, etc. Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface". An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). The use of pumping/spraying machines specifically designed to be used with fibre-reinforced structural mortars is recommended. For the spraying of structural mortars such as Repar Tix HG SB, an effective and sometimes prolonged mixing of the product, which must take place upstream of the pumping circuit, is always recommended. For this reason, the use of “plaster sprayers” with volumetric water dosage is not recommended. Pour about 2/3 of the mixing water into the mixer, add Repar Tix HG SB and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 16% of the weight of the bag. Addition of Bond HG to the mixing water, (approx. 0.5 litres per 25kg bag of product) in the single component version, allows further improvement in terms of adhesion, hold, impermeability, workability, modelling and deformation capacity. In the case of use of the product in the two-component version, pour component B (liquid) into the mixer, gradually adding component A (powder) and mixing until the lumps are completely eliminated. For high coating thicknesses, static requirements, monolithic requirements, etc., performed with Repar Tix HG SB, it is advisable to use suitable metal reinforcements (electro-welded mesh, cages, etc.), anchored to the support with Syntech Profix, GROUT MICROJ, Repar Tix G2. Approximately 18,5 kg/m² of Repar Tix HG SB for every centimetre of thickness to be implemented (approximately 1850 kg per cubic metre). Bag 25 kg - Pallet: 50 x (Bag 25 kg)

Grout 6 HP SFR Grout 6 HP SFR is a fibre-reinforced high-performance castable mortar, equipped with mechanical compressive and flexotraction resistance far superior to normal structural mortars. It is used for repairs, replenishments, strengthening concrete reinforcement and special works in FRC. The mix of special metal fibres (Readymesh MM-150) and synthetic fibres (Readymesh PM-060) is able to drastically reduce or even eliminate plastic-hygrometric shrinkage and the development of exceptional characteristics of ductility, fracture energy, resistance to shock and dynamic stress. With very low water-binder ratios, Grout 6 HP SFR makes it possible to achieve compacting and hyperfluid rheologies that favour the movement of the mortar and the perfect filling of reinforced sprays, even with narrow spaces between the bars. The microsilica with pozzolanic activity increases the cohesion of the mixture with typical anti-segregating and anti-run-off effect. The particular fineness of the hydraulic binders contained in the formula promotes adherence to the substrate and has an effect of enlarging the fibrous components. The fibre mix offers strong ductility, toughness and flexotraction resistance to the castings performed with Grout 6 HP SFR. With regard to the ANTICORROSIVE and PROTECTIVE FUNCTION ON THE REINFORCEMENT BARS, the main features of Grout 6 HP SFR are: • the mix of high-strength superfine binders, combined with very fine silicas with pozzolanic activities, to render the mortars intrinsically impermeable to water at the end of the hardening process; • The strongly alkaline pH (> 12) protects the reinforcement bars from triggering corrosion; • The negligible breathability of the carbon dioxide ensures hardened mortars with extremely prevalent anti-carbonation characteristics. Overall, these anticorrosive specificities render the classic treatment of reinforcement bar passivation, preparatory to the pouring of castable mortar UNNECESSARY, provided that not too much time passes between the white metal cleaning operations and the castings of pourable mortar, at the risk of new oxidative processes being triggered. Thus, only in the event that long exposure times are foreseen between the bar-cleaning operations and the pouring of castable mortar is it advisable to treat with passivating slurry (Repar Monosteel or Repar Steel), applied by brush and only on the reinforcing bars. On-site castings or pumping carried out for any kind of structural replenishment of reinforced concrete, seismic reinforcement and adjustment, increases in cross-sectional resistance of concrete structures and masonry, anchorages of large-scale machinery (especially in the presence of significant dynamic stresses), anchoring of port bollards, deep-drawing and reinforcement works, restoration of highly-stressed industrial flooring both from a static and dynamic perspective, restoration of degraded foundations on bridges and viaducts especially whereby necessitating rapid reopening to vehicle traffic, construction of structures designed with HPC (High Performance Concrete) needs. Application surfaces must be clean, free of dust, contamination, crumbling, inconsistencies, etc., and adequately saturated-surface-dry with water. An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). Mix the entire content of a bag of Grout 6 HP SFR with effective vertical-axis mixers for at least 6 minutes, initially introducing a slightly reduced amount of water (9% = 2.25 litres/25 kilograms bag) compared to the required total water permitted (10%–12% = 2.5litres — 3.0 litres/25 kilogram bag) whilst mixing for at least 4 minutes. After this mixing time, evaluate the consistency of the mixture and, if necessary, gradually add in the last of the water until achieving the desired workability, without exceeding the limit of 12% (3.0 litres/25-kilogram bag), mixing at high RPM for at least another two minutes. For thick casting sections, it is advisable to add Ghiaietto 6.10 (consult the relevant technical data sheet or ask for more information on the appropriate dosage of Ghiaietto 6.10 from our technical service). Given the self-levelling properties of the product and its self-compacting capacity, paying due attention to the vibration phase is recommended. Excessive zeal in the vibration operation can worsen the aesthetic rendering of the end result. Do not use in the absence of suitable lateral containment. Ensure exposed surfaces are protected and wet-cured. Adopt casting procedures to ensure the absence of voids and discontinuities. Only pour the mortar from one part of the casting perimeter to avoid air pockets. Packaging: 25 kg bag UM: €/kg

Osmocem Quick Cement compound for instantaneously stopping water leaks in underground rooms or above-ground structures, even in the presence of negative thrust pressure. Based on rapid hardening and high resistance hydraulic binders of ultrafine quartz aggregates, shrinkage compensators, micronized hydrophobic products and specific additives for the regulation of rheology. It does not contain chlorides. Mixed with water it gives rise to a mixture of thixotropic plastic consistency, easily applied even vertically, which hardens in 30" - 60", adhering perfectly to the roughened support. Immediate stop of water infiltrations in building structures: basins, tanks, cellars, lift shafts, drains, underground masonry, etc. Examples of use: waterproof sealing of cracks and holes, waterproof repair before the addition of concrete, waterproofing systems made in combination with Flexseal 300 hydro-expansive sealant and waterproof mortars of the OSMOCEM line. Thoroughly clean the contact surfaces. In the case of cracks, discontinuities, cavities, etc. preliminarily prepare application sections countersinking towards the inside of the masonry, creating a "dovetail" shape (in order to facilitate the hydraulic sealing of the intervention). Remove any detached residual material from the prepared site, by means of pressure washing and jets of compressed air. Any interventions on temporarily dry surfaces require wetting of the support to saturation. Mix with water, if possible at a temperature not less than 20°C, no more than 250-300 cc per kg of product. The product reacts immediately and it is very quick, therefore mix from time to time the quantities of product strictly necessary and immediately applicable. Apply the product on site by hand exclusively and immediately after mixing the product with water while wearing protective rubber gloves. Press the mixed product firmly into the slot or hole and hold this pressure until the setting is complete (approx. 120 – 180 seconds). In case of multiple leaks, start the application of Osmocem Quick from the higher water leaks. Where necessary, in case of pressure infiltrations, proceed with the installation of drainage with a plastic tube, with small diameter, initially sealing sections adjacent to the drainage and then, once you stop the infiltration, sealing the drainage itself. Approximately 17 kg/m² of Osmocem Quick for every centimetre of thickness to be implemented (approximately 1700 kg per cubic metre). Packaging: 25 kg bag UM: €/kg

Grout 2 HP Grout 2 HP is a pourable, fiber-reinforced mortar, used for structural restoration operations, anchoring of steel bars and strands, reinforced micropiles, tie rods, and riveting. The formulation contains very fine high-strength cements, micro-silicas with pozzolanic activity, aggregates in a rational granulometric curve (0.1 ÷ 1.8 mm), and special antisegregative additives. The product is mixed with 11% - 12% of water, requiring vigorous and prolonged mechanical mixing. The special formulation of Grout 2 HP provides the castings with mechanical strength, fracture energy, exceptional durability, and very high chemical-physical resistance. Grout 2 HP has a workability time of about 60-90 minutes, after which the setting process is triggered, followed by progressive hardening. The plastic and hygrometric shrinkage is extremely low thanks to the presence of Readymesh PM-060 multifilament synthetic fibers, which provide volumetric stability. The performances that make Grout 2 HP unique are: • very high compressive mechanical strengths (> 90 MPa at 28 days), • very high mechanical resistance to bending-traction (> 12 MPa after 28 days), • excellent durability and resistance to chemical attacks. Grout 2 HP is used for structural restoration operations, anchoring of steel bars and strands, reinforced micropiles, tie rods, and riveting. It is particularly suitable for operations where high mechanical performance is required after short curing (compressive strength at 3 days > 60 MPa) and in operations carried out in severe exposure environments (XC - XS - XF), characterized by aggression from sulphates, chlorides, and nitrates. The material can also be used for repairs in anchoring areas subject to high stresses. The application surfaces must be clean, free of dirt, crumbly and incoherent parts, dust, etc., and suitably saturated with water until reaching the condition of "saturated with dry surface". Adequate roughening of the surfaces by scarifying, sandblasting, etc. is always necessary to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). It is strongly recommended, for optimal performance of site operations, to use a vertical axis mixer with planetary movement or a double horizontal helicoid. The powder is mixed with drinking water to the extent of 11% - 12%, referring to the total weight of the mortar (about 2.75 liters per 25 kg bag) until a homogeneous mixture is obtained. Mixing time: about 4 minutes with a high efficiency mixer. The anchoring can be filled with a single screw pump, for mortars. Pumping must be carried out at a controlled speed to ensure a low working pressure. In case of restorations, the surface must be protected, after application, by polyethylene sheets or anti-evaporation treatments. Packaging: 25 kg bag Unit of Measure: €/kg
