Advanced Lifeline

Sewage Pipe Renewal

Sewerage pipes are rehabilitated by lining the inner surface with hard polyvinyl chloride materials in a spiral shape, achieving longer lifespans. There is no need to dig up roads, construction periods are significantly shortened, and emission of industrial waste, such as soil and sand, is greatly reduced.


These are Japan’s first hard polyvinyl chloride pipes. The inner surfaces are smooth, and they are highly resistant to corrosion, light, and easy to work with. For over half a century, we have been supporting water supply and drainage infrastructure essential for life with our rich lineup of products with high performance meeting the needs of the times.


European railways and metro operators are slowly starting to adopt glass fibre-reinforced synthetic sleepers as a more durable alternative to wood. Sekisui produced its first plastic sleeper in 1978 in response to a demand from Japanese railways for a material that was more resistant to weathering than wood. Plastic sleepers have been installed widely across the country since the mid-1980s, particularly on switches, turnouts, bridges and other projects where maximising maintenance intervals is a priority. 


CROSS-WAVE is a plastic material of underground rainwater storage / recharge system constructed by piling up. Since it was launched in 1993, it has established the number one position in the industry as achieving 3,800 cases of construction and 1,000,000m3 of total storage capacity. Especially, its staggered structure provides outstanding structural stability and security that it has been widely used.

Packaging tape

We offer a wide range of tapes which can be used for various applications depending on the base material. In addition, we also have environmentally friendly products which use fewer resources (by using recycled materials) and reduce waste.
