Concrete Canvas®” certified as “VE evaluation” by NETIS.

(Tokyo Head Office: Setagaya-ku, Tokyo; Osaka Head Office: Yodogawa-ku, Osaka; President: Yumi Nomura), a manufacturer of large membrane surface structures (tent structures), civil engineering and logistics materials, and other products, has announced that its geosynthetic cement composite mat “Concrete Canvas Concrete Canvas®, a geosynthetic cement composite mat that can build a highly durable concrete layer simply by applying water, was certified as a “VE evaluation” technology (a technology whose effectiveness has been evaluated) by the New Technology Information System (NETIS) operated by the Ministry of Land, Infrastructure, Transport and Tourism, as of September 25, 2025.

Registration No.	CG-220009-VE
Name of Technology	Concrete Canvas® Method
Evaluation Date	September 25, 2025
Abstract	This technology is a simple method of forming a thin, high-strength, high-durability lining layer by spraying and permeating water from the surface onto a fabric material (Concrete Canvas®) with special cement sealed inside in advance to fill the inner cement with water, hydrate, and harden it.

Concrete Canvas® is a composite material called “Geosynthetic Cementitious Composite Mats (GCCM)” (ASTM D8364) developed in the UK. It consists of specially formulated dry concrete enclosed in a three-dimensional woven fabric (surface: woven polyester fabric, backside: PVC film). After spreading the mat, the dry concrete hardens by sprinkling water or submerging it in water to create a thin, highly durable, fire-resistant concrete layer. This product has been widely used in slope protection, weed and bamboo control, waterway construction, and waterway repair work.

Concrete Canvas®, which can create thin, highly durable, watertight, and fire-resistant concrete surfaces simply by applying water, does not require heavy machinery or special skills for on-site casting. It was also used in the restoration of the Suemasa River embankment breach caused by the July 2025 torrential rains in western Japan, and in the construction of the west face of the Maiko Bridges (completed in July 2025) by Sanyo Electric Railway Co. The floor surface of the Expo sauna “Taiyo no Tsubomi “* was also used, taking advantage of the characteristics that make it easily adaptable to complex shapes.

*Expo sauna “Taiyo no Tsubomi”: An event sponsored by the organizers of the 2025 Japan International Exposition (Expo ’70 Osaka-Kansai). Taiyo Kogyo designed and constructed “Taiyo no Tsubomi” as a Silver Partner.
