We offer waterstops, hydrophilic water sealing materials, and waterproof geomembranes to support the safety and function of social infrastructure, using various materials, such as synthetic resins and synthetic rubber, to develop or propose products that meet the customer’s needs and purposes. We have earned customers’ trust as a specialist in waterproof geomembranes and water sealing materials, from manufacturing of membranes necessary for civil engineering to supplying related materials, to carrying out construction for waterproofing.
We develop and offer waterproofing materials manufactured from hydrophilic resin, which absorbs and expands with water, with the concept of “control water with water.” This product assists our daily life in areas that we do not often notice—such as the Tokyo Bay Aqua-Line and subways.
Hydrophilic water sealing materials that are formulated and molded by specially processing water-absorbing resin with synthetic rubber. It is used as a water sealing material in underground tunnels between segments.
Hydrophilic water sealing materials that have a unique form, used in civil engineering or construction, such as cast-in-site concrete joints.
We offer a diverse product lineup for sealing and waterproofing, featuring various items according to customer’s use and construction methods.
We offer a diverse lineup with various thicknesses, widths, lengths, surface textures, and colors using plastic resin such as PVC, EVA and PE.
These waterproofing panels are flexible, easy to work with, and durable. They are used to stop water at construction expansion joints in cast-in-site concrete, structures.
Our company’s waterstops comply with JIS standards.
