NETIS registered product! Maintains water tightness and strength of concrete for a long period.

Japan Structural Treatment Co., Ltd.'s "Concrete Modifier" is a highly multifunctional product that achieves low cost while providing "high waterproofing performance," "prevention of salt damage and freeze damage," and "suppression of carbonation." It is an innovative "silicate-based" product that excels in workability and long-term durability. Utilizing a wealth of "nano-sized" silicates derived from the latest nanotechnology, the fundamental principle of "penetrating the RC surface → filling voids → solidifying" is effectively demonstrated in a wide range of usage environments. The 'RC Gardex Waterproofing' product will surely satisfy both clients and contractors, becoming an essential item for future RC structures. 'RC Gardex Waterproofing' is an environmentally friendly concrete modifier that penetrates deeply into concrete, efficiently preventing water leakage, corrosion, and efflorescence. It also prevents dust and effectively removes oil from the surface and interior of the concrete, serving as an effective primer for further surface treatment agents. Additionally, the application of RC Gardex Waterproofing suppresses the growth of bacteria, moss, and algae. It also prevents the corrosion of steel materials and maintains the appropriate pH within the concrete, which is crucial for preventing concrete deterioration.

Inorganic concrete permeable modifier RC Gardex CV

NETIS registered product! It has reduced expansion force and improved durability against freeze damage.

Nihon Kutaishori Co., Ltd.'s "Concrete Modifier" is a highly multifunctional product that achieves low cost while offering "high waterproofing and water-stopping performance," "prevention of salt damage and freeze damage," and "suppression of carbonation." It is a new concept "silicate-based" product that excels in workability and long-term durability. Utilizing a wealth of "nano-sized" silicates derived from the latest nanotechnology, the fundamental principle of "penetrating the RC surface → filling the voids → solidifying" is effectively demonstrated in a wide range of usage environments. 'RC Gardex CV' will surely satisfy both clients and contractors and become an essential item for future RC structures. 'RC Gardex CV' densifies concrete structures and suppresses the intrusion of water and chloride ions. Additionally, the gel-like reaction products (inorganic polymers) generated within the voids are resistant to freezing, and even if they do freeze, the volume expansion is reduced to one-fifth due to the lowering of the freezing point of water. The gel structure is also flexible, resulting in less expansive force and improved durability against freeze damage. For more details, please contact us or refer to the catalog.

For preventing concrete deterioration! Reactive silicate-based surface impregnation material Real Maintenance.

Achieving the long lifespan of concrete structures through excellent neutralization suppression effects, eliminating the need for cumbersome watering curing, contributing to labor and cost savings! NETIS!

The reactive silicate-based surface impregnation material, Real-Mente, is a surface impregnation agent for concrete modification and deterioration prevention that has been uniquely formulated to mitigate the reaction with free calcium in concrete, which inhibits the penetration amount and speed of the main component, silicates. NETIS Registration Number: KT-080018-VE 【Specifications】 20 kg in a poly container 【Features of Real-Mente】 ◆ Exhibits excellent carbonation suppression effects. ◆ Eliminates the need for water curing, enhancing work efficiency. ◆ Possesses high waterproofing effectiveness. 【Reason for No Need for Water Curing】 The issue of internal penetration inhibition of the main component due to reactions with free calcium and metals, which was a challenge with conventional silicate-based concrete modifiers, has been resolved with a completely new formulation, allowing for the penetration of the main component deep into the concrete. For more details, please refer to the catalog!

Silicate-based surface impregnation material "Real Maintenance" for concrete neutralization.

One application only, no need for watering curing! It allows for a reduction in the construction process!

"Real-Mente" is a surface impregnation material that employs surface protection methods, surface treatment methods, and surface impregnation methods, consisting of a mixture of three types of silicates. It is registered as a NETIS design comparison technology under No. KT080018-V. By addressing the issues of conventional silicate-based concrete modifiers, such as the phenomenon of internal penetration inhibition of the main components due to reactions with free calcium and metals through a new formulation, it has enabled the penetration of the main components into the interior of the concrete. As a result, watering for curing is unnecessary, and it has high penetration power. 【Features】 ■ Suppresses concrete carbonation, freeze damage, salt damage, and alkali-aggregate reactions ■ No need for watering during curing ■ Shortens the construction process ■ No concerns about runoff into rivers or oceans *For more details, please refer to the catalog or feel free to contact us.
