Carbon fiber and aramid fiber sheet repair and reinforcement method construction - Reliable reinforcement construction

We support various continuous fiber sheet reinforcement methods and protect asset value with reliable technology, primarily in the Kanto region.

Using sheets of carbon fibers or aramid fibers, which are lightweight, high-strength, and excellent in corrosion resistance, arranged in one direction or two directions, we reinforce structures by impregnating them with a special epoxy resin and adhering them to the surfaces of concrete or wood. This method is highly effective for reinforcing areas lacking rebar, improving bending and shear strength, suppressing cracks, and enhancing fatigue durability. It adds almost no weight and does not impose a burden on existing structures. It is applicable not only to wooden houses but also to reinforced concrete and steel structures. The Wood Preservation Center has numerous construction achievements, mainly in the Kanto region, and provides consistent support from suitable reinforcement design to construction with reliable technology. If you are considering improving the performance of your building or maintaining its asset value, please feel free to consult us.

Introducing the latest mold removal and prevention treatments.

A professional strike that works on the core of mold.

MOLTES is a new mold treatment system that eliminates and prevents mold from the root by sequentially using three types of liquid agents. The construction procedure is as follows: 1st Liquid (Chaser): An acidic citric acid-based solution that penetrates deep into the mold due to the effect of surfactants, inactivating the mold spores. 2nd Liquid (Gladiator): An alkaline liquid agent based on high-concentration hypochlorous acid water that reacts with the 1st liquid to neutralize and effectively remove mold and discoloration. 3rd Liquid (Conciliator): A neutral liquid agent that combines polyaminopropyl biguanide (PHMB) with metal ions that have photocatalytic effects, providing an antibacterial coating to prevent mold recurrence. This system has a proven track record in food factories, hotels, supermarkets, and warehouses, and since it becomes almost neutral after application, no washing or wiping is necessary, reducing the burden on workers.

Measures against small animals for underfloor ventilation openings

Small Animal Entry Point Number 1

The most likely entry point for small animals into the building is the external ventilation ducts. Even if there is wire mesh, there may be large gaps on the upper left and right sides, or it may be damaged or missing due to rust and corrosion. The droppings and urine of small animals that have entered the building can lead to the proliferation of mites and affect the sanitary environment. Installing wire mesh without gaps will prevent the intrusion of small animals.

RC structure concrete repair work

Technology to stop deterioration, the power to restore durability.

Even if the concrete is chipped as shown in the photo, it is possible to carry out repairs. First, clean the bonding surface with a grinding process and carefully apply rust-inhibiting primer (Asahi Bond Rust-Inhibiting Primer) to the rebar sections. Next, use epoxy resin (Tafron G-2030) to inject into the joint area to prevent any gaps. After that, evenly apply epoxy mortar (Asahi Bond BE13) to the joint area. This process is similarly applied to the side of the chipped concrete. Finally, ensure that the joint is firmly adhered and take measures to support it from below with wood to prevent any falling.

Installation of new ventilation ducts.

A new breeze breathing from the basics—comfortable spaces start here!

When installing new ventilation or air vents in the foundation, please limit it to foundation concrete without rebar. In structures such as slab foundations, drilling holes in the foundation is prohibited as it may reduce seismic strength. The work procedure is as follows: 1. Determine the position and size of the vent Draw a line on the foundation as a marker according to the size of the vent you want to install. 2. Drill holes Drill multiple holes along the drawn line. 3. Chisel away Using a chisel, carve along the holes made by the drill. At this time, if you use a grinder to smooth the foundation along the line, you will reduce the risk of over-carving unnecessary parts during the chiseling work. 4. Caution when using a grinder When using a grinder, please work while spraying water to suppress dust. 5. Carve from both inside and outside Use the chisel to evenly carve from both the outside and inside to shape it. 6. Finishing Once the rough shape is created with the chisel, wet the surface of the foundation with water and use mortar to smooth out any unevenness. Finally, the work is complete once the mortar has dried.

Floor insulation renovation

The temperature variation in the room is reduced, making the floor and walls warm and comfortable! It also improves condensation on walls and windows.

We would like to introduce the "floor insulation renovation" that can be carried out while living in the home. Since the work is done from below the floor through an inspection opening, there is no need to move furniture or relocate. The insulation work takes approximately 1 to 2 days, which minimizes the burden on the homeowner. By enhancing insulation performance, the surface temperature rises, making it feel sufficiently warm even at a room temperature of 20°C. Additionally, because there is less temperature variation indoors, both the floor and walls can be warm and comfortable. 【Effects】 ■ Improvement of perceived temperature ■ Measures against heat shock ■ Improvement of condensation on walls and windows *For more details, please feel free to contact us.

Mortes

Kill, remove, and prevent mold with three types of liquid agents! Suitable for use on walls in food factories and refrigerated warehouses.

"Moltes" is a product composed of three liquid agents: "Chaser (mold killer)," "Gladiator (mold killer/bleaching)," and "Conciliator (mold prevention)." After treating with "Chaser (blue liquid)" at around pH 3, treating with "Gladiator (yellow liquid)" at pH 12 causes a rapid neutralization reaction that breaks down both the mold itself and the pigments. Mixing citric acid and sodium hypochlorite at around pH 3 produces almost no chlorine gas, making it safe to use. Unlike general cleaning agents that use sodium hypochlorite, there is no need to rinse after treatment. Once it has dried to some extent, the mold prevention agent "Conciliator" can be applied. 【Three Liquid Agents】 ■ Chaser - Main ingredient: Citric acid (less than 2%) ■ Gladiator - Main ingredient: Sodium hypochlorite (effective chlorine concentration less than 3%)/Sodium hydroxide (less than 0.05%) ■ Conciliator - Polyhexanide (less than 0.1%)/Titanium dioxide *For more details, please download the PDF or feel free to contact us.

Bait method

Considerate of the environment by not spraying liquid agents! Termite prevention is possible without conducting work indoors.

The "bait method" is a termite control method that does not involve the use of chemical agents. A bait that termites prefer is placed in a special container called a "station," which is buried in the ground. Worker termites carry it back to the nest, leading to their extermination. The chemical agents are effective against molting organisms such as insects. Therefore, their impact on humans, dogs, cats, and other mammals, as well as fish, is extremely minimal. [Overview (partial)] ■ Method: Stations are installed around objects (no chemical treatment needed inside buildings) ■ Effect: A molting inhibitor is mixed with food that termites prefer, causing them to consume it and aiming for the extermination of the entire colony ■ Effective period: Effective as long as the bait is in place ■ Chemical used: Molting inhibitor *For more details, please download the PDF or feel free to contact us.

Toreka Cross Method

Adoption of fabrics with resin intrusion confirmation features that can easily prevent human errors such as unintentional intrusion.

The "Toreka Cross Method" is a reinforcement technique for concrete structures using high-quality carbon fiber Toreka cloth. When resin is impregnated, it changes from white to transparent. The impregnation state can be visually confirmed during construction, making it easy to prevent human errors such as unimpregnated areas. By applying Toreka cloth in the vertical direction (bending reinforcement) and horizontal direction (shear reinforcement), the concrete is constrained, resulting in increased ultimate displacement and improved seismic performance. [Reinforcement Effects] ■ Seismic reinforcement for bridge piers and buildings ■ Improved compressive toughness ■ Enhanced bending strength ■ Reinforcement of crack areas *For more details, please download the PDF or feel free to contact us.

Methods for termite extermination from outside the floor.

No worries even if there is no underfloor space in your home! Ensure thorough termite prevention with exterior soil treatment.

Termite extermination and prevention is typically carried out from beneath the floor. However, in homes without a crawl space, it is difficult to perform work from below, so our company conducts "peripheral soil treatment," which involves injecting chemicals into the soil around the building. The chemicals used for termite control include preservatives and antifungal agents, and the most effective method is to spray them directly onto the wooden components from below. However, even when work cannot be done under the floor, peripheral soil treatment can effectively prevent termite intrusion. Peripheral soil treatment provides solid protection for the exterior of the building and reliably blocks the pathways for termite entry. It has received positive feedback from many customers as a measure that allows them to continue living comfortably even without a crawl space.

Reinforced concrete explosion repair work

Explaining the importance and maintenance of basic concrete, as well as the neutralization of concrete and its effects!

The foundation concrete supports the weight of the house and is structurally very important. Typically, the foundation is made of durable reinforced concrete. When the rebar rusts, it expands, and if this progresses, it can lead to the destruction of the concrete. If the crack width reaches 0.3 mm and the missing part is 5 mm, the risk of rainwater infiltration increases. Concrete has a strong alkaline nature after being poured, which protects the rebar from corrosion. *For more detailed information, you can view the related links.

Protecting your home from mold and decay: Achieve a clean living environment with professional mold removal services.

Those who control mold control the home: Essential knowledge and measures for mold prevention.

In high-temperature and high-humidity environments like Japan, mold can easily thrive, and various materials in the home can serve as a nutrient source for mold. This includes wood, paint, and adhesives. Special attention is needed during the rainy season and in winter when high airtightness can lead to condensation, as these conditions particularly encourage mold growth. In apartment buildings and condominiums, condensation is common, increasing the risk of mold development. Proper ventilation, humidity control, and regular cleaning are key measures to prevent mold. *For more detailed information, you can view the related links.

Half a century of expertise in the wood preservation business.

Quality that lasts and a promise for a sustainable future. Japanese wooden architecture: Tradition and innovation.

Japanese architectural culture has utilized wood as a primary building material since ancient times. Wood is a natural material suitable for Japan's humid climate, and its warmth and beauty have been deeply rooted in the lives of the Japanese for a long time. Wooden structures are appealing due to their harmony with nature, flexibility, and earthquake resistance. However, wood has the potential to decay over time and is susceptible to damage from pests such as termites and woodboring beetles. With the evolution of construction technology, wooden architecture has recently become larger in scale, and buildings with more complex structures are increasing. *For more detailed information, please refer to the related links.

Peace of mind home inspection.

Providing professional inspection services (building surveys) to ensure the safety and durability of structures.

In April 2018, the Real Estate Transaction Act was amended, making it mandatory for real estate agents to inform both sellers and buyers about building condition surveys during the sale of used houses. While the amendment does not go as far as making surveys mandatory, it is undoubtedly a step that will increase in the real estate and construction industries. In metropolitan areas, the rise in real estate prices has led to an increase in property transactions, and there are currently very few companies specializing in inspections of crawl spaces, buildings, and attics. *For more detailed information, please refer to the related links.
