sanwalivacon.com is the official corporate website of Japan-based Sanwa Rivacon Co., Ltd. The company is a specialized construction enterprise focused on deterioration protection and waterproof sealing for concrete structures, primarily offering Rivacon construction method services. Its core product is a highly permeable concrete modifier manufactured by Rivacontech.
The website provides a full introduction to the principles and advantages of its construction technology: The product is a harmless inorganic liquid. After being injected into concrete, it forms cement crystals that fill internal voids to achieve high-density modification. This not only provides waterproof sealing, but also inhibits concrete carbonation and alkali-aggregate reaction, extending the service life of the structure. Compared with traditional surface waterproofing, this technology can be applied from any side of the structure, works for both newly built and existing concrete structures, delivers semi-permanent results after a single application, requires no follow-up maintenance, and even comes with a 10-year waterproof warranty. For pricing, the public reference unit price for projects over 300㎡ including labor is 4,400 JPY per square meter; the final price is adjusted based on actual on-site construction conditions.
Advantages: This technology solves the pain points of traditional surface waterproofing, which tends to peel off and requires repeated maintenance. The material is safety-certified, passing Japan's drinking water facility safety testing, so it can be used for water supply projects with excellent environmental performance. It also has fewer construction restrictions, shortens overall project timelines, and delivers lower overall long-term costs.
Disadvantages: The company only serves the domestic Japanese market, so users outside of Japan cannot directly access its services. The official website only offers content in Japanese, which is not user-friendly for non-Japanese speakers.
This website can currently be accessed directly via public network in China, no proxy tool is required, and the loading speed is normal.
