Concrete modification waterproofing agent "Radomist"

Concrete modification waterproofing agent "Radomist"

Purely made in Japan, achieving significant cost reduction and stable supply. New properties come with a 10-year waterproof warranty.

"Radmist" is a product that, when applied or impregnated on concrete surfaces, generates a gel that fills pores and voids, enhancing waterproofing and durability. In addition to significantly improving surface hardness and abrasion resistance, it can self-repair by generating gel again if cracks occur and rainwater seeps in. For new construction projects, it comes with a 10-year waterproof guarantee, and we provide free crack maintenance and follow-up inspections. 【Features】 ■ Long-term suppression of carbonation deterioration ■ Purely made in Japan, achieving significant cost reduction and stable supply ■ Guarantees cracks of less than 0.5mm for new construction projects ■ Exceeds the durability standards set by the Japan Society of Civil Engineers "JSCE-K 572" ■ Suitable for waterproofing in parking lots *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Reinforced concrete modifier, water stop, and waterproofing material "Tomenite"

Reinforced concrete modifier, water stop, and waterproofing material "Tomenite"

A new concept that makes concrete itself a thick waterproof layer! It excels in permeability and demonstrates high effectiveness.

"Tomenaito" is a modified waterproofing and water-stopping material for reinforced concrete that achieves water resistance and waterproofing simply by being applied to concrete floors and walls. It can be used in various locations such as apartments, buildings, and multi-story parking lots. After drying, the potassium silicate that remains on the surface and inside the concrete reacts with rainwater, effectively addressing newly formed cracks. Additionally, by reacting with calcium hydroxide in the concrete to produce calcium silicate, it suppresses the formation of calcium carbonate, preventing water intrusion and the oxidation (rusting) of rebar, thereby extending the lifespan of the concrete. 【Features】 ■ Self-water-stopping reactivity ■ High permeability ■ Suppression of neutralization ■ Densification ■ Shortened construction period and significant cost reduction *For more details, please download the PDF or feel free to contact us.
