A must-see for those struggling with the renovation of asbestos-containing coatings! Achieve prevention of peeling at the same time!

A new proposal to prevent the dispersion of asbestos! What is the 'Net Barrier Method' that can renew the building's finish without the need for coating removal and prevent exterior wall peeling?

Are you facing any of these issues with asbestos removal work? - Unable to start construction due to a lack of manpower... - Even while progressing with the removal, problems arise during surprise audits, making it difficult to advance the work... - Buildings like schools and public facilities bear risks as they cannot extend the construction period... and more. Renotech's self-developed 'Net Barrier Method (Composite Exterior Renovation Construction Method)' will solve these problems! - The 'Net Barrier Method' is a responsible construction method that applies existing techniques, requiring minimal training for managers and workers. - Developed as a pin-net method, it reduces the risk of asbestos dispersion by covering rather than removing it. - With minimal substrate treatment, new paint finishes or tile finishes are possible! - Asbestos-related work only requires the removal of the coating by drilling a Φ10.5mm hole before pinning! - In some regions, it may be considered "small-scale work" and exempt from asbestos regulations. - A dispersion confirmation test conducted by a third-party organization has been completed! No asbestos detected. - With the legal amendments enacted in April 2021, regulations regarding work on asbestos-containing coatings have been relaxed, making work easier. *For more details, please download the PDF or feel free to contact us.

Soil Pressure Support Method "Multi Board (Retaining Wall) Method"

We will support the soil pressure on the PCa version using commonly available piles!

The "Multi-board (Retaining Wall) Method" is composed of piles and PCa panels (precast panels), and it is a method designed to support the earth pressure acting on the PCa panels with the piles. The standard spacing for pile installation is 4 meters, and to transfer the earth pressure from the PCa panels to the piles, the PCa panels are fixed to the front face of the piles using connecting fittings. This allows for a retaining structure that does not expose the piles, resulting in an aesthetically pleasing appearance. 【Effects】 ■ By combining H-shaped steel as the parent pile with PCa panels, the structure does not require a base slab, which reduces the excavation width, making it possible to construct in sites where securing excavation width is difficult. ■ Since a base slab is not required, this structure reduces the number of pile foundations, the amount of foundation concrete, and the volume of excavation, enabling cost reduction and shortening of construction time. *For more details, please download the PDF or feel free to contact us.

PCR method for road use

Construct cross-structures safely and reliably without excavation! It minimizes deformation and suppresses subsidence of the upper pavement.

The "PCR Method for Roads" is a construction technique that allows for the parallel advancement of small-element PCR girders underground while utilizing the railway and road above. This method introduces prestressing to safely and reliably construct crossing structures without excavation. Depending on the support method of the PCR girder and the arrangement of PC steel materials, various forms such as lower girders, box-shaped tunnels, and circular tunnels can be selected. Since it is a pushing method using small elements, the thrust force is small, resulting in a compact reaction force facility. 【Features (Constructability)】 ■ Minimal impact on the upper road surface ■ Small thrust force, leading to a compact reaction force facility ■ No transportation of soil ■ Capable of handling gravel, cobblestones, and obstacles, ensuring high pushing accuracy ■ Smaller work yard can be accommodated *For more details, please refer to the PDF materials or feel free to contact us.

RSP lift-up construction method

Construction is possible even in narrow spaces such as under railway viaducts! Steel plate wrapping vertical reinforcement method using lifting.

The "RSP Lift-Up Method" is a construction technique that allows for the installation of steel plate wrapping in a narrow working space without the need to demolish or remove nearby structures. Reinforced steel plates that have been divided are assembled on the ground, and using an electric hoist installed on top of the bridge pier, the reinforced steel plates are lifted. By repeating this process of lifting and assembling the next reinforced steel plate underneath the lifted one, the reinforced steel plates are installed on the bridge pier. Additionally, if the footing is located underground and excavation is not possible, the use of the pier-reflection method for the press-in section allows for the installation of steel plate wrapping without excavation. 【Features】 ■ Construction is possible with a working space of about 1.0m ■ No need for demolition or restoration of nearby structures ■ Excellent cost-effectiveness ■ Minimizes social and business losses for facilities under elevated structures ■ Uses small, divided materials, eliminating the need for large heavy machinery *For more details, please refer to the PDF document or feel free to contact us.

SSP construction method

Improving the seismic performance of pile bent piers! It is economically advantageous as large-scale temporary structures are not required.

The "SSP Method" is a reinforcement technique that can improve the seismic performance of pile bent bridge piers under strict constraints, such as directly beneath existing structures, without the need for large-scale temporary facilities, and without significantly altering the landscape or the river's cross-sectional area. By wrapping reinforcement steel plates around existing piles and driving them in, and integrating them with the existing piles using underwater non-separating non-shrink mortar, the seismic performance is enhanced. 【Features】 - Safe construction while maintaining the use of the existing bridge - No need for large-scale temporary facilities (temporary closures, temporary piers) - Excellent cost-effectiveness - Minimal impact on the river's cross-sectional area during and after construction - Can minimize the impact on navigation routes and rivers *For more details, please refer to the PDF document or feel free to contact us.

Reinforcement work for existing rockfall protection fence "Reinforced Fence Type L"

Ideal for improving the insufficient height of existing rockfall protection fences and addressing aging issues.

The "Reinforced Fence L Type" is a reinforcement method that addresses the improvement of insufficient fence height and countermeasures for aging existing fences. By reusing the existing retaining wall, the construction period can be shortened compared to conventional measures. Previously, improving insufficient fence height required the removal and reinstallation of the fence or raising the height of the retaining wall with concrete. The Reinforced Fence L Type allows for the installation of new post bases on the retaining wall while keeping the existing posts in place, enabling the erection of new posts. This simple process reduces the overall cost of the project. ■ Compatible with falling rock energy below 61 kJ ■ Reuses existing retaining walls of falling rock protection fences ■ Reduces waste materials and lowers environmental impact ■ Shortens construction period and reduces waste disposal costs ■ Reduces road occupancy time during construction ■ Can be installed with a simple process *For more details, please download the PDF or feel free to contact us.
