Deep Insilan, a silane-based impregnation material.

Achieves a state of high strength and extreme resistance to degradation through the bonding of silicon and oxygen (siloxane bond)!

"Deep Insilan" is a silane-siloxane based impregnation material that forms a high-density water-repellent layer by penetrating the concrete surface, effectively preventing the long-term intrusion of external deterioration factors through high water repellency. The water-repellent layer blocks moisture and chloride ions from the outside, while allowing water vapor from within the concrete to pass through. Additionally, this product causes minimal surface changes after application, maintaining the texture of the material over a long period. Please feel free to contact us if you have any inquiries. 【Benefits】 ■ Extended lifespan ■ Suppression of deterioration progression ■ Surface protection ■ Increased durability ■ Prevention of deterioration factor intrusion, etc. *For more details, please download the PDF or contact us.

Introduction of the grating "Safety Walker L.D."

A new type of grating that matches urban landscapes: "Safety Walker L·D."

The "Safety Walker L·D" is suitable not only as grating for on-site pouring but also for various types of drop-in and bolt-fixed covers, raised types, and other special dimensions.

The grating is clogged, and it looks like... "Safety Walker"?

The grating is clogged with small stones and debris, making it look unappealing... But with the "Safety Walker," due to its design, it is less likely to clog, more durable, and lightweight.

The "Safety Walker G・D" and "Safety Walker L・D" are an evolved type of grating that, compared to conventional grating, is less prone to clogging from small stones and debris, always maintaining hygiene, has an attractive appearance, and is less likely to break due to its surface material structure, making it useful in various scenes. In addition to being used as grating for on-site casting, it can also be used for various types of recessed and bolt-fixed grating, raised types, and other special dimension covers (please consult us for concrete secondary products, etc.). Due to its structural design, the surface is made of material that is strong against twisting and impacts from vehicle tires, making it difficult for the grating to break. It is also suitable for preventing grating damage. Moreover, due to its structure, the grating itself is less likely to become clogged with stones or debris, preserving the landscape. Multiple slit holes are made in the surface material of "striped steel plates" or "patterned steel plates," balancing drainage and strength. It has also been reported that its anti-slip effect exceeds that of conventional types. It is recommended for areas where grating frequently gets damaged, such as near entrances, or where tires from forklifts and large vehicles tend to break it.
