Renotech has been involved in general repair work as a professional since its establishment. The pin-net method "Net Barrier Method P1" is effective in preventing the peeling of exterior wall finishing materials (tiles and mortar) from buildings. 【What are the differences from conventional pin-net methods?】 ■ The powder used requires no "mixing agent" and only needs water added for mixing! Base adjustment, net installation, and finishing can all be handled with just one type of material. ■ No need to apply primer to existing substrates and pin heads! *Some conditions apply; see the notes below. ■ No need for resin injection into anchor pins! ↓ As a result… ☑ Simplification of processes leads to reduced construction time. ☑ Reduces costs for powder mixing agents, primers, and injection materials, as well as the hassle of disposing of empty cans. ☑ Fewer items reduce the burden of order management and inventory management. Additionally, this method allows for the covering of existing finishing materials (such as tiles) with a new paint finish, maintaining aesthetics while also reducing waste disposal costs. Furthermore, by using a robust net and core rod-driven anchor pins, it provides excellent peeling prevention effects and comes with a 10-year warranty. *For more details, please refer to the PDF document or feel free to contact us.

The Ministry of Education also recommends the "long-life renovation of school facilities," which can secure an educational environment equivalent to that of a rebuild while keeping costs lower than rebuilding. However, depending on the degree of deterioration of the exterior walls, it may not be possible to complete the work during the school's vacation period. Particularly with tiled exterior walls, the removal of existing tiles will also be necessary. However, the "Net Barrier Method" developed by Rinotech is a new pin-net method that allows new tiles to be installed over existing tiles, leading to a significant reduction in construction time. Additionally, with high-strength substrate construction, there have been no incidents of falling debris in buildings that are over 10 years old. 【Features of the Net Barrier Method】 ■ Reliable construction with a responsible construction system ■ Reduction of industrial waste, making it economical and environmentally friendly ■ Simplification of work and increased construction efficiency with shorter construction periods ■ Simplification of site management ■ Securing an educational environment equivalent to that of a rebuild *For more details, please refer to the PDF materials or feel free to contact us.

Typically, when completely renovating a building with exterior wall tiles or replacing cracked tiles and missing parts with new tiles, it is necessary to remove all existing tiles using tools like a chisel and create a new substrate. Therefore, the costs for repairs and renovations will include removal costs, waste disposal fees, noise control measures, and more. However, with the "Net Barrier Method" developed by Rinotech, it is possible to apply new tile finishes or paint finishes while leaving the existing tiles in place! ★What is the reason for this…? By driving special stainless steel anchor pins through a network layer that compresses three-dimensional fibers into polymer cement mortar down to the structural body, it prevents the finishing material from falling off. Additionally, the three-dimensional fibers create a suitable base for tiling with a raised texture, and by embedding into the tile adhesive mortar (anchoring effect), it strongly prevents the new tiles from falling off. The Net Barrier Method is operated under a responsible construction system by members of the "National Aero Association." With qualified personnel across the country handling construction and management, we can ensure high construction quality, so please feel free to consult with us! *For more details, please refer to the PDF materials or feel free to contact us.

Rinotech's automatic low-pressure resin injection method, "Aero Plate Method," is a simple resin injection technique that replaces U-cut seals during concrete crack repairs. Because it injects at low pressure, it can completely fill even fine cracks in the substrate without damaging the concrete, making it suitable for use in narrow spaces. Additionally, since it is a single-use type, we offer it at a lower price compared to reusable types. It is recommended for those who say, "I don't have time to clean the injection equipment, and I don't have enough manpower!" 【Features】 ■ Small protrusion from walls and floors, making gondola work easy ■ Can be installed upside down on ceiling slabs, etc. ■ Compatible with familiar grease guns ■ Long hole-shaped outlet allows injection along cracks ■ Easy management of injection volume as the remaining resin can be checked at a glance 　(Utility model registered) *For more details, please refer to the PDF materials or feel free to contact us.

The "Replex Sheet" used in the net barrier method is a three-dimensional mesh non-woven fabric made from aramid fibers, which are used in aircraft and bulletproof vests. It is flexible, highly resistant to alkalis, and maintains durability even within cement mortar. Even after the finishing layer experiences shear failure due to short-term large stresses or long-term repeated stresses, the raised portions of the net act to keep the finishing piece in place without detaching, thereby creating a safe and durable wall surface. 【Specifications】 ■Specification: Net pitch 10mm ■Packaging: 1m width × 50m/roll *For more details, please refer to the PDF document or feel free to contact us.

The "Net Barrier Method," a patented technology by Rinotech, aims to prevent the peeling of deteriorated exterior walls such as "mortar-finished walls" and "tiled walls," while enhancing the asset value of the building. By directly covering surfaces with asbestos-containing finishing materials using this method, it eliminates the dispersion of asbestos, allowing for a safe renovation of the building. (Proven results already!) 【Recommended for those who:】 ■ Want to renew their building but face extended construction periods due to asbestos-containing materials... ■ Are incurring double costs for asbestos removal and renovation work... ■ Need quick construction timelines while ensuring high-quality renovation work, such as in schools... Public institutions have also conducted verification tests, yielding results with no asbestos detected. *As of April 2021, the conditions for removing asbestos-containing building finishing materials using power tools have been relaxed to: - Maintain constant moisture - Isolate with plastic sheets, etc. The drill used for the Net Barrier asbestos countermeasure specification is a water-circulating, vibration-free type that fully meets these conditions. Additionally, the notification process has been simplified, making the construction even easier.

Many buildings still use paint materials containing asbestos, and while there is pressure to remove or demolish them, there are no established methods, making removal time-consuming and labor-intensive. Additionally, there are issues such as a shortage of experienced asbestos removal workers and a lack of high-pressure washing machines. As a result, even if one wants to "renew the building," it is difficult to start renovation work until the asbestos removal is completed. The renovation construction method "Net Barrier Method (Composite Exterior Wall Renovation Method)," developed in collaboration with major companies, aims to prevent the peeling of deteriorated "mortar-finished exterior walls" and "tiled exterior walls," and it can be adapted for work on surfaces with asbestos-containing finishing materials! (Proven results☆) 【Features】 ■ Some areas may be treated as small-scale work! Just remove the coating by creating a Φ10.5mm recess before pinning! ■ Confirmation tests conducted by public institutions! No asbestos detected ■ Prevents lifting and peeling of finishing materials!

The "Nox Anchor" is a stainless steel anchor pin with an injection port designed for repairing floating issues in exterior wall mortar and tiles. Its stepped head structure and the splayed tip enable "fixed ends" that prevent the expansion of floating areas due to resin injection pressure (co-floating phenomenon). The combination of mechanical fixed ends and resin injection effectively prevents detachment. The dedicated bit allows for two tasks (pre-drilling and seat carving) with a single hole, ensuring both ease of work and reliable construction. 【Features】 ■ Prevents the enhancement of floating due to injection pressure during injection ■ Synergistic effect of anchor and resin adhesion ■ Applicable to relatively high injection pressures such as slurries ■ The anchor is made of stainless steel, offering excellent corrosion resistance ■ The small diameter type "MNA" can also be used for fixing mosaic tiles *For more details, please refer to the PDF document or feel free to contact us.
