Leave the concrete construction in the Tohoku area (Miyagi Prefecture, Yamagata Prefecture, Fukushima Prefecture, Iwate Prefecture, parts of Akita Prefecture, and Kitaibaraki City) to us. The winter in Tohoku is a battle against "frost damage," where the moisture inside the concrete freezes and expands repeatedly. It is not uncommon for surface troubles, such as peeling, to occur within a few years with standard finishes. Our "Vacuum Concrete Method" thoroughly removes excess moisture immediately after pouring, creating an extremely dense concrete structure that prevents moisture intrusion. This achieves overwhelming durability that resists frost damage. **Three Reasons Why Tokuwa Industry is Chosen Locally** Coverage of neighboring prefectures and quick on-site response: We cover areas including Miyagi, Yamagata, Fukushima, Iwate, parts of Akita, and Kitaibaraki. From site adjustments before construction to tight deadlines, we respond with the quick footwork unique to the local area. Rich construction experience in commercial facilities and incinerators: We have accumulated know-how in construction in harsh environments, such as supermarkets, home centers, and incinerator platforms, where many vehicles pass by daily. *For more details, please download the PDF or feel free to contact us.*

Are you struggling with issues like "post-pouring setbacks and early deterioration" at your design and construction sites? "Cracks and peeling (pop-outs) frequently occur on steep slopes due to freeze-thaw cycles in winter..." "Large vehicles and heavy machinery frequently pass through, causing the surface to wear down badly within a few years, increasing repair work..." "The original delivery deadline is tight, and we want to shorten the curing period (waiting for hardening) by even one day after pouring..." Tokuwa Kogyo's "Vacuum Concrete Method" fundamentally resolves these site complaints. By forcibly dehydrating and pressurizing excess moisture with a vacuum mat immediately after pouring, it demonstrates the following strengths: [Dramatic Improvement in Strength]: Maximizes compressive and tensile strength as well as surface hardness, effectively suppressing cracking. [Durability through Densification]: Reduces porosity and improves waterproofing, protecting the surface from wear and freeze damage for an extended period. [Early Rise in Initial Strength]: Dehydration accelerates hardening, achieving high strength in a short curing period, significantly shortening construction time. *For more details, please download the PDF or feel free to contact us.

In underground parking lots, durable flooring is required to make effective use of limited space. It is particularly important to prevent wear from vehicle traffic and deterioration due to moisture penetration. The vacuum concrete method enhances the strength and wear resistance of concrete, enabling long-term use. 【Usage Scenarios】 - Flooring in underground parking lots - Space-saving - Improved wear resistance 【Benefits of Implementation】 - Increased durability of flooring - Reduced maintenance costs - Feasibility of long-term use

The vacuum concrete method involves covering the surface with a vacuum mat immediately after concrete placement and using a vacuum pump to remove some of the water from the concrete while simultaneously applying pressure to the concrete due to atmospheric pressure. Concrete treated with the vacuum method achieves increased compressive strength, tensile strength, and surface hardness compared to normally finished concrete. 【Features】 ■ In slabs, it is possible to increase density, improve waterproofing, reduce porosity, and enhance abrasion resistance. ■ It has significantly higher strength than normally finished concrete with a shorter curing period. ■ It has high initial strength, increased long-term strength, abrasion resistance, and freeze-thaw resistance, reduces hardening shrinkage, and enhances water tightness. *For more details, please download the PDF or feel free to contact us.
