"Bitoguraut-N" is a waterproofing agent for sealing leaking cracks and construction joints. It accommodates various injection methods from low to high pressure. It has re-alkalization properties and stable waterproofing performance over the medium to long term. The injection volume varies depending on the thickness of the concrete and the width of the cracks. 【Features】 ■ Direct repair (waterproofing) of leaks from cracks, construction joints, cold joints, etc. ■ Improvement of water paths that have been neutralized (accompanied by efflorescence) due to leakage. *For more details, please refer to the PDF document or feel free to contact us.

• Waterproofing Agent

Our company employs the "Vito Packer Method," which involves repairs using a combination of materials that are extremely resistant to weathering and deterioration in concrete structures suffering from water leakage. Using a packer for injecting materials, we first inject water ceramic into the deteriorated areas of the concrete. This allows the material to deeply penetrate into the concrete, effectively sealing fine cracks and preventing weakening due to the outflow of components. Subsequently, we inject a long-term stable water-stopping agent, "Vito Grout-N," to completely block the water pathways. 【Features】 - High adhesion allows for long-term water-stopping effectiveness. - Water-based materials result in low environmental impact. - No volume reduction or permeability after curing. - No grinding work is required, and with a small drilling diameter of 10mm, noise is minimal. - Structural damage is minimized, allowing for quick construction. *For more details, please refer to the PDF document or feel free to contact us.

Our company offers the "Bitogrout-R Method" for the regeneration of waterproofing layers in existing structures. This method involves injecting a water-based emulsion resin into the existing waterproofing layer, integrating it with the structural concrete and the topping mortar. It can be applied even if moisture remains in the existing waterproofing layer. 【Features】 ■ Regeneration of the waterproofing function of the old waterproofing layer ■ Cost reduction through shortened construction time ■ Simultaneous repair of deteriorated concrete areas ■ Applicability even if moisture remains in the existing waterproofing layer ■ Minimal noise and vibration, with no generation of concrete waste *For more details, please refer to the PDF materials or feel free to contact us.

• Renovation and repair methods

Our company employs the "Bitogrout-UG Injection Method," which completely seals leaks in underground structures and ensures long-term stability through the formation of external waterproofing. We drill a penetration hole in the back surface of the concrete structure and inject a water-based emulsion resin from there towards the inside. The resin permeates and backflows through various leak paths, forming a new waterproof layer. Additionally, this method allows for water stoppage over a long period of 10 to 25 years (with proven results), significantly reducing maintenance costs. 【Features】 ■ Enables water stoppage for a long period of 10 to 25 years (with proven results) ■ Low maintenance costs ■ Possesses stability performance that can be referred to as "post-construction external waterproofing" ■ Strong adhesion ensures long-lasting water stoppage effects ■ No volume reduction or permeability after curing *For more details, please refer to the PDF document or feel free to contact us.

At the National Sanatorium Nagashima Aiseien Rejuvenation Dormitory, gentle measures using water ceramic have been implemented to preserve the weathered appearance of the mortar, which has deteriorated over 87 years, and to resist further weathering in the future. To address blackening caused by biological growth, we avoided strong cleaning that would remove everything and instead aimed to penetrate the mortar with water ceramic to eliminate the organisms internally. We believe that the blackening after construction will become thinner due to self-cleaning effects, restoring the original color of the mortar. ■ Issues - Weathering of the mortar over a long period ■ Construction Case - Penetration of biological eradication into the mortar using water ceramic * For more details, please refer to the PDF document or feel free to contact us. * You can download case studies showing before and after results.

At the Tottori Prefecture's Encho-en, a trial was conducted using water ceramic to address algal proliferation. The effectiveness was tested at eight locations within the park, including marble stone lions affected by algal blooms and white granite that had turned black due to cyanobacterial growth, where water ceramic was applied. Later, the algae and fungi on the marble stone lions were removed through water ceramic treatment, and the surface of the treated white granite no longer absorbed rainwater. Similar effects were observed at six other locations. **Features of Water Ceramic:** - Prevention of mold, algae, fungi, and moss growth - Recovery and strengthening of the deterioration of concrete and stone surfaces - Restoration and enhancement of moisture-proof and waterproof performance of exterior wall tiles, stone, and concrete surfaces - Stability of color and texture of concrete surfaces after application - Restoration and strengthening of important structures *For more details, please refer to the PDF document or feel free to contact us.*
