CS-21 has been certified as a material by JR West.

Water stopping, waterproofing, surface protection, cross-section repair, crack repair, and waterproof treatment of construction joints and wooden formwork for concrete structures, CS-21.

CS-21 is a colorless and transparent aqueous solution of inorganic nature. Developed by Aston Co., Ltd. in 1993, it is a domestically produced material. ■Features: Contains reactive components that enhance hydration, demonstrating effectiveness regardless of the age of the concrete. ■When applied to the surface of concrete, it fills fine cracks and voids, such as construction joints, which are difficult to see visually, thereby densifying the surface layer. Additionally, through ongoing reactions under moisture supply from rainwater and other sources, it fills newly generated fine voids after application, suppressing the progression and expansion of cracks. These properties help maintain the integrity of the cover concrete and suppress the intrusion of water and various deterioration factors (such as steel corrosion) over the long term. ■In the civil engineering field, it is applied for preventive maintenance against water penetration, neutralization, salt damage, freeze damage, etc., as well as for surface protection methods and durability improvement measures for cracks and construction joints. In the architectural field, it is used in waterproofing methods for new constructions (such as rooftop parking lots, basements, water tanks, etc.). ■Material classification: According to the design and construction guidelines (draft) for silicate-based surface impregnation methods in Concrete Library 137 of the Japan Society of Civil Engineers, it is classified as a "reactive silicate-based surface impregnation material." In the old classification of the surface protection method design and construction guidelines (draft) in Concrete Library 119, it is categorized as "sodium silicate-based surface impregnation material" based on its main component, and it corresponds to "when intended for waterproofing" based on construction specifications.

Measures to improve the durability of concrete joint connections.

By applying the liquid material "CS-21" along the concrete joints, the intrusion of water and deterioration factors from the joints is suppressed. *It can also be applied to fine cracks (approximately 0.2 mm or less) that are not subject to injection methods and minor cold joints (those with color differences but without clear separation).

CS Mini is a spray bottle type of "CS-21." By applying it in advance to areas prone to leakage, such as construction joints, it suppresses the formation of voids at the concrete (mortar) interface and prevents water leakage. *For treatment of construction joints with "CS-21," please refer to the technical documentation: CS-21 Construction Joint Treatment. By applying it from the surface along cracks and construction joints, it suppresses the intrusion of water and deterioration factors (steel corrosion) from cracks and joints, thereby improving durability. *For measures to enhance the durability of cracks and construction joints using "CS-21," please refer to the technical documentation: Measures to Enhance Durability of Cracks and Construction Joints Using CS-21 Coating Method.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four configurations: left, center, right, and a total of 12 spots. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor with a single model. 【Recommended for such locations!】 ☑ Entrance facing a busy corridor ☑ Counter or sign near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Grabee is a next-generation monitoring solution equipped with new features specialized for forest fire and wildlife damage prevention, based on AI video analysis and location estimation technology developed at Guardian. In addition to the conventional location estimation function, it now includes flame identification and animal identification capabilities, enabling early detection and response to forest fires and wildlife damage. Furthermore, it supports mapping of fire areas and area calculations.
