Emergency restoration method "Dantan": A new technique by the sinking correction expert Upcon.
Quickly restore road unevenness and depressions during an earthquake with polyurethane resin, enabling swift vehicle passage. Contributing to the establishment of emergency transportation routes!
The new method "Emergency Restoration Method Dantan" developed by Upcon involves spraying high-strength polyurethane resin onto road unevenness caused by disasters during earthquakes to create a slope, enabling temporary vehicle passage for the early establishment of emergency transportation routes. A truck equipped with all necessary materials rushes to the site and sprays a two-component polyurethane resin onto the created unevenness. The high-strength polyurethane resin has the property of hardening immediately after spraying, allowing for vehicle passage within 15 minutes after the slope is created. Additionally, it can be used to repair not only unevenness but also depressions and subsidence. Features of the Emergency Restoration Method Dantan: - Ability to create slopes tailored to the shape of the disaster-affected site - Resolution of unevenness in about one hour, allowing immediate vehicle passage Furthermore, it has a proven track record in correcting tilts and unevenness of concrete floors and pavement slabs caused by earthquakes or ground subsidence, as well as filling voids. [Exhibiting at EE Tohoku '23] We will be exhibiting at the comprehensive exhibition of new technologies, EE Tohoku '23. At our booth, we will conduct demonstrations using polyurethane resin. Location: Yume Messe Miyagi Dates: June 7 (Wed) - 8 (Thu) Booth No: West Hall Exhibition B-708

basic information
Upcon's main business is to correct the sinking, tilting, steps, and gaps in concrete floors caused by uneven ground subsidence in buildings such as factories, warehouses, stores, and general residences using our unique "Upcon Method," which employs completely non-fluorinated urethane resin and small machinery. Additionally, to promote new business development, we are advancing numerous projects and engaging in research and development for new application fields of rigid foam urethane resin, aiming to create a cycle of developing our business while creating our own market as a research and development-oriented company. ■ What is the Upcon Method? For existing concrete floors and concrete pavement slabs that have experienced sinking, steps, tilting, voids, or gaps, we drill small holes with a diameter of 16mm and inject urethane resin while continuously monitoring the floor level in millimeter increments. The resin injected beneath the floor or slab expands under pressure in a short time, compacting and strengthening the ground, improving the bearing capacity, and pushing up the concrete floor or pavement slab from below to correct it. Even if voids or cavities occur beneath the floor or slab, we fill the gaps with urethane resin using the same method.
