"Mejikara" is a construction method primarily designed to prevent water leakage from the joints of bench flumes. The key point is to apply it to dry concrete and ensure a membrane thickness of 2mm. With fewer steps, it can be installed by anyone, and it has received positive feedback from agricultural and water conservation management organizations, as well as construction contractors. [Features] - Prevents water leakage from the joints of bench flumes - Few steps, making it possible for anyone to install - There are case studies where almost all joints have maintained a sound condition even after 20 years *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our joint repair method, "Mejimoru/Mejimoru Underwater Type." "Mejimoru" is a method that uses a high-performance mortar with a compressive strength of 40N/mm² or more, combined with a formulation of resin and fibers that provides stable adhesion and crack resistance. The "Mejimoru Underwater Type" can be applied simply by mixing it with water, allowing for the repair of damaged areas in concrete structures that are constantly submerged in water. 【Features of Mejimoru】 ■ Can be applied by one person at a rate of 20m to 30m per day ■ Very easy to use, as it only requires the addition of water ■ Uses high-strength mortar with a compressive strength of 40N/mm² or more ■ Stable adhesion due to the formulation of resin and fibers ■ High-performance mortar with crack resistance *For more details, please refer to the PDF document or feel free to contact us.

The "Lastalk Tower Rust Treatment Agent" is a product that utilizes the function of suppressing corrosion under the coating through "chelation" effects, ensuring the prevention of residual rust formation and stabilizing it. It forms a stable chelated iron film that halts the progression of rust. A strong binder reinforces the chelated iron film, blocking external corrosive substances. By adopting a resin paint that enhances drying and adhesion properties, it possesses adhesion performance that is less likely to cause coating peeling. 【Features】 ■ Ensures corrosion suppression performance under the coating through "chelation" effects ■ Utilizes functions to stop and stabilize the formation of residual rust ■ Adopts resin paint that enhances drying and adhesion properties ■ Possesses adhesion performance that is less likely to cause coating peeling ■ Pursues long-term durability through joint development with electric power companies *For more details, please refer to the PDF document or feel free to contact us.

• Rust Inhibitor

The "Thick Film Line" is a special masking tape designed for thick film coatings and resin mortars. It has a standard size of 2mm x 20mm x 8m and can be easily cut by hand to your desired length. It can be used for marking thick edges and as a reference for film thickness management when applied at specific points. 【Features】 ■ Compatible with thick film coatings and resin mortars ■ Standard size of 2mm x 20mm x 8m ■ Easily cut by hand to your desired length *For more details, please refer to the PDF document or feel free to contact us.

The 'Kiri no Futa' is a waterway cover made from thinned wood. It was constructed to prevent slope collapses caused by pests and to stop waterways from being blocked by weeds. It can also help prevent accidents from falls. Each piece weighs approximately 1.7 kg, reducing the burden of transportation and installation. Additionally, a special harmless chemical is injected throughout the material, allowing for long-term durability. [Features] ■ Inexpensive ■ Lightweight ■ Maintains strength ■ Biodegradable ■ Harmonizes with nature *For more details, please refer to the PDF document or feel free to contact us.

The "OM Lining Method" is a waterway protection and repair technology aimed at extending the service life of waterways by quickly forming a strong waterproof membrane on concrete surfaces. Thanks to its anti-corrosion technology, it is durable over the long term while maintaining flexibility. Additionally, both the friction coefficient and roughness coefficient are low, which improves water flow and reduces the accumulation of mud. 【Features】 ■ Slippery surface ■ Sustained flexibility ■ Wear resistance ■ Improved roughness coefficient ■ Ice detachment properties *For more details, please download the PDF or feel free to contact us.
