【Large Logistics Center Floor】◎Surface Reinforcement◎Concrete◎Case Study◎Seal Hard

The floor of the logistics center is constructed with the "Seal Hard Standard Specification." This is the basic standard specification of Seal Hard. It is a floor finish that is supported in domestic logistics.

The flooring of the logistics center was constructed using the standard specification of "Seal Hard." The customer is a company that consistently handles the provision, inbound and outbound storage, and transportation of the logistics center, and they chose "Seal Hard." What stood out during our meetings was the customer's request for a "high-quality, strong floor." There are many surface hardening agents available domestically. For 27 years, we have consistently focused on "quality." We thoroughly penetrated and reinforced the concrete with "Seal Hard." While applying the material generously increases the labor involved due to residue removal, it also enhances the "strength of the floor = quality." We were particularly pleased that the customer prioritized quality and arrived at "Seal Hard," which motivated us in our work. In the logistics center, the size and the lack of other equipment make the floor stand out. We performed careful polishing, applied "Seal Hard" to the maximum penetration limit, ensured adequate curing time, and did not forget to remove any residues. By faithfully adhering to the basics and not skimping on effort, we achieved a finish that has gloss and a sense of cleanliness, even with the standard specification. We hope that when you seek quality flooring, "Seal Hard" will be the first thing that comes to mind.

Entrance + Warehouse Floor: Penetrating Concrete Surface Strengthening ◎ Seal Hard

Entrance + Warehouse Floor: Penetrating Concrete Surface Strengthening ◎ Seal Hard

The floor, which serves as both an office and a warehouse, was constructed with "Seal Hard Premium." It is a two-story wooden building, and the work was done on the first floor.

In 2019, we applied 【Seal Hard Premium】 to a wooden building that serves as both an office and a warehouse. Upon entering, the concrete base is revealed, and we worked on the entrance and warehouse areas. The design features a double-height space that allows the office on the second floor to overlook the warehouse. I have previously attended sites where the wall finish was "wood" and the floor finish was "concrete," and this combination has a very good aesthetic compatibility, which I personally like. The warmth of the wood adds to the inorganic impression of the concrete. The client is a specialized trading company. They sought a durable floor for inventory management and a beautiful gloss to welcome customers. 【Seal Hard Premium】 is a special specification that has also been adopted in the 21st Century Museum of Contemporary Art and the Hirosaki Brick Warehouse Museum. The application was divided into two rounds, with the second round involving polishing using diamond blades. The finish retains as much of the concrete's cement layer as possible. This combines the beauty of the finish with the wear resistance and dust-proof effects of Seal Hard. In smaller projects, mechanical finishing cannot be used for the floor, often resulting in a plaster finish. However, in this case, we were able to use mechanical finishing, resulting in a beautiful floor.

【教会の床】表面強化材■シールハードプレミアム■21世紀美術館同

【教会の床】表面強化材■シールハードプレミアム■21世紀美術館同

教会の床をシールハードプレミアムで施工。信仰・交流・出会いの場である【教会】にもシールハード、コンクリート素地仕上が有効です。

新築の教会のホール・カフェ部分に【シールハードプレミアム】を施工しました。 開放感があり多くの採光を取り込める窓、自然を感じられる優しい木ベンチ・家具。 これらの環境と【シールハードプレミアム】の上品な光沢との相性は抜群。 打合せに行き、建物を見た際に「この教会は綺麗になる」と確信し元請ともスムーズに打合せが進みました。 規模は200ｍ2程の規模、夏場のコンクリート打設という条件でした。 シールハードと同メーカーが作る【E-CON】を使って鏝ムラや表面剥離・ひび割れを軽減しました。 【シールハードプレミアム】は2回施工。 工期を分ける理由、それは良い下地を1回目の施工で作る為。 コンクリートの素地を仕上として用いる為、下地が悪ければ美しくは仕上がりません。 1回目で滑らかで強度ある下地を作り、2回目で磨き上げる。 時間とお金がかかりますが、それに見合う品のある仕上がり・光沢が望めます。 教会、安らかに心を落ち着けられる場であると思います。 そんな雰囲気にもよく似合う仕様が【シールハードプレミアム】 丁寧に仕上げた床、一度ご体感頂けたらと思います。

[Ground Management Building Floor] Concrete Base Finish ◎ Example ◎ Seal Hard

[Ground Management Building Floor] Concrete Base Finish ◎ Example ◎ Seal Hard

The floor of the school's ground management building was constructed with "Seal Hard." It is a floor finished while keeping maintenance easy and costs low in a building adjacent to the ground.

We applied Seal Hard standard specifications to the management building of the school grounds. Inside the management building, we finished the floors of all rooms, including changing rooms, instructor rooms, entrances, storage rooms, and laundry rooms, with concrete base and Seal Hard. When I actually looked at the drawings and went for a site survey, I felt that Seal Hard was a good match. What is necessary for managing the grounds is "maintenance management and ease of use." This point perfectly aligns with the advantages of Seal Hard. The building is where athletes return after playing sports. Naturally, dirt and dust will come in. However, with the concrete finished with Seal Hard, a quick mop cleaning can make it spotless. Additionally, a well-wrung mop provides the Seal Hard floor with just the right amount of moisture, allowing the concrete to grow stronger and develop a glossy finish. The management building is a place that is not often exposed to many people. However, it is an essential facility and also serves as a place of relaxation after club activities. We ensure that we carry out precise construction in such seemingly ordinary places, creating floors that are easy to use and appreciated. When considering the construction of the management building, please remember Seal Hard.

Factory floor surface reinforcement material ■ Seal Hard ■ Oil absorption suppression ■ E-CON

Factory floor surface reinforcement material ■ Seal Hard ■ Oil absorption suppression ■ E-CON

The factory floor is finished with two applications of Lion Seal Hard and Petrotex (oil absorption suppressor). It is a special specification for aesthetics, low maintenance, wear resistance, and oil countermeasures.

We applied 【Lion Hard + Seal Hard + Petrotex (oil absorption suppressor)】 at a factory in Fukui Prefecture. Additionally, we used a special specification with E-CON (pouring aid). The customer custom-makes processing equipment such as press processing. They encountered the Seal Hard floor during a visit to another factory and expressed interest. We then conducted a hearing on the factory's overview. Since they mentioned that oil mist was generated, we proposed "Petrotex" as a solution for floor contamination. Petrotex is a permeable material that can add an "oil absorption suppression" effect to the floor treated with Seal Hard. The appearance after application does not compromise the gloss of Seal Hard and helps reduce the absorption of water and oil. Moreover, since large machinery will be used, we opted for a two-layer specification of Lion Hard and Seal Hard for increased strength. We also suggested E-CON, which is effective for summer pouring. Using E-CON helps suppress rapid moisture evaporation during concrete pouring in the summer. I will never forget the words from the representative after the installation: "It's a great floor, and I'm happy it looks clean." This was a floor we could propose from the planning stage, and it was finished with high quality.

[Factory Floor of Molds] Surface Reinforcement Material ■ Seal Hard ■ Oil Absorption Suppression ■ E-CON

[Factory Floor of Molds] Surface Reinforcement Material ■ Seal Hard ■ Oil Absorption Suppression ■ E-CON

The floor of the mold factory has been finished with Seal Hard W specification and Petrotex (oil absorption suppressor). Please take a look at this special floor designed with oil mist countermeasures in mind.

We applied the 【Seal Hard W specification + Petrotex (oil absorption suppressor)】 at the press mold factory. Additionally, we used a special specification with E-CON (membrane curing agent). The customer was a highly specialized company that develops press molds nationwide. During the meeting, it became clear that the work within the factory was diverse. They mentioned the installation of a 250-ton processing machine, which would involve oil-based processing. With the presence of forklift traffic, I thought a simple specification would lead to a mismatch, so I proposed the following specifications: - 【Seal Hard W】 to enhance wear resistance and strengthen the floor - 【Petrotex_Oil Absorption Suppressor】 to reduce oil stains - 【E-CON】 to minimize plastic cracking that tends to occur during summer pouring I was shown the existing factory, where the green painted floor was peeling. They were struggling with maintenance issues there as well. The strength of Seal Hard is that it is free from peeling and lifting. They appreciated the quality of a finish that can last long. The customer was surprised to see how beautiful the floor looked after the application, saying, "Can concrete look this good?" Easy maintenance with regular water wiping is sufficient. Please consider this for finishing in factories and similar settings.

【スケートパーク路面仕上】グリーンパークだいもん

【スケートパーク路面仕上】グリーンパークだいもん

スケートパーク広場の床にシールハードを施工しました。外部でも長期間コンクリートを保護し、快適な滑り心地にした床に仕上げました。

富山の公園に一部をスケートパーク広場に改修する工事を行いました。 実際に滑るスケーターに既存パークの滑り心地をヒアリングしたことがあります。 「ザラザラして滑りにくい」、「床がザラついて、タイヤの摩耗が激しい」、「騒音が大きいと近隣住民から言われる」、「転ぶ際のケガが怖い」など多くの悩みを聞きました。 そんなお悩みに解決策になったのが【シールハードFGS仕様】でした。 ・床を削り・磨く→滑らかな床が仕上がる。 ・シールハードで表面強化する→耐摩耗性が上がりコンクリートの質を上げる。 そして外部の床に最適なのが【アクアペルプラス_吸水抑制剤】です。 酸性雨などをコンクリートに浸透させない様にし長寿命化を図りました。 滑り心地を保つためにカッター目地に【SSP100_目地充填】も施しました。 弊社の施工班にはプロを目指すスケーターがいます。 彼らに実際に滑ってもらうと 「この床はいい！！」と笑顔で滑っているのを見て、こちらまで嬉しくなりました。 現状、スケートボード広場に最適な仕様だと思います。 是非見て、触って、滑ってください。良さが分かると思います。 ご検討ください。

NIX Street Sports Park, a park that produces Olympic athletes.

NIX Street Sports Park, a park that produces Olympic athletes.

The park, which had deteriorated after 8 years since its establishment, has been reborn with a long-lasting surface.

NIX Street Sports Park" located in Toyama City, Toyama Prefecture is a well-known park that was established as a large-scale facility in the Hokuriku region and has produced bronze medalists for the Tokyo Olympics. However, starting from its third year, the surface began to deteriorate significantly, and by the eighth year, the poor condition of the surface, which was comparable to asphalt, led to a reputation of "a well-designed park but with the worst surface." During the renovation work, a large American grinding machine was used to grind down the rough concrete surface, and the sunken areas were filled with a special resin from the U.S. that can be used outdoors, creating a smooth surface. Additionally, a penetrating surface hardener called "Seal Hard" and a water absorption inhibitor named "Aqua Pel Plus" were applied to enhance wear resistance and rainwater resistance. Not only did the surface become smooth again, but it was also finished to be a long-lasting surface with wear and rainwater resistance! Since Hokuriku is particularly known for its high precipitation, such specifications are essential for concrete parks. After the construction, local skater and Paris Olympic participant Kana Nakayama announced on Instagram, "It has really become easier to skate!

"Skate park surface finishing in the adjustment pond" Toyo Carbon Urban Sports Park

"Skate park surface finishing in the adjustment pond" Toyo Carbon Urban Sports Park

The newly constructed concrete surface of the adjustment pond has been finished with a long-lasting concrete surface that is resistant to "wear" and "rainwater."

In Marugame City, Kagawa Prefecture, we carried out construction to renovate a retention basin into an urban sports park. We have actually interviewed skaters about their experience with the existing park. They expressed many concerns such as: "It's rough and hard to skate," "The floor is gritty, causing excessive tire wear," "Nearby residents say it's too noisy," and "I'm afraid of getting injured when I fall." The solution to these issues was the "Seal Hard Skate Park Specification." - We ground and polished the floor to create a smooth surface. - We reinforced the surface with Seal Hard to improve wear resistance and enhance the quality of the concrete. The main factor causing damage to the concrete surface is "rainwater." If the park within the retention basin does not have a rainwater-resistant surface, it will deteriorate in just a few years. The solution to this problem was the "Aqua Pel Plus - Water Absorption Suppressor," which prevents acidic rain and other elements from penetrating the concrete, thereby extending its lifespan. During the opening ceremony, seeing skaters glide with smiles, exclaiming, "I've never skated on such a smooth floor before!" made me realize that this specification is optimal for the skate park.

Concrete surface finish for the "skate park" [with pavement specification].

Concrete surface finish for the "skate park" [with pavement specification].

The future skate park must be "durable." Let's take a look at what happens if we just "pour and finish"!

We would like to introduce the importance of the concrete surface finish "Skate Park Specification" that our company is currently constructing, along with some examples. Do you have any concerns about the concrete surface at your skate park? - The concrete is deteriorating, and before you know it, the surface has become rough in just a few years. - It is difficult to secure a budget for repairs, and it is being used in its damaged state. - There is a risk of injury due to the poor surface condition. - It is not possible to create a safe and smooth skate park. Many of the above issues are caused by simply pouring concrete without further treatment. Our company aims to solve these challenges and create parks where "the surface lasts longer" and "users can skate safely." In setting up the park, we have created a "Construction Case Collection" and a "Surface Specification Document" for the Skate Park Specification, so that those involved can gain a better understanding of skate parks. We can carry out construction for both "new installations" and "renovations." Our staff includes skaters who aspire to be professionals. Currently, we feel that this specification is suitable for skateboard plazas. *For more details, please download the materials or feel free to contact us.

"Professional riders are amazed by the smooth surface!" Ishioaka Skateboard Park

"Professional riders are amazed by the smooth surface!" Ishioaka Skateboard Park

Important from the start! We have finished the new concrete pavement with a long-lasting surface that is resistant to "wear" and "rainwater."

A skateboard park completed at the east exit of JR Ishioka Station in Ibaraki Prefecture has undergone construction to create a long-lasting concrete surface! Skate park construction commissioned by local governments is often contracted to local civil engineering companies, which may not be accustomed to managing large concrete surface installations. Due to pouring concrete on a hot, sunny day in March, there were many rough areas on the surface, and we finished it to create a smooth surface suitable for skateboarding, including corrections for those rough spots. At the opening ceremony, there was a demonstration by professional riders, and it was a huge success with comments like, "It's super easy to skate on!" Many attendees mentioned they had never encountered such a surface before. We hope to introduce this surface to many users in future new and existing parks, while preventing the deterioration of the parks and ensuring the safety of users.

One way to reduce the cost of setting up a skate park is...

One way to reduce the cost of setting up a skate park is...

I will convey one proposal to resolve the issue of "cost" while actually installing within the budget!

Skate parks are often said to have a "concrete surface" as the basic standard, and the installation costs are high! This is because skateboarding, which is a sport involving wheel diameter, can lead to "serious injuries" if the condition of the concrete is poor, making it impossible to settle for a mediocre surface condition, which requires time and effort. However, there are ways to reduce costs! Our company has the know-how to transform even poorly conditioned concrete surfaces into smooth, long-lasting surfaces. Only Willbee can finish existing parks to a level that surpasses new constructions. Both "new installations" and "renovations" will be transformed into long-lasting surfaces with minimal injury risk.

Surface deterioration is best addressed early! NIX Urban Sports Park

Surface deterioration is best addressed early! NIX Urban Sports Park

Deterioration began one year after the new installation, so renovations were made before significant deterioration progressed!

The "NIX Urban Sports Park" was established in Toyama City, Toyama Prefecture in 2023. It is a park supervised by Kaede Nakayama, a bronze medalist at the Tokyo Olympics. During the construction of the new facility, a permeable surface hardener from another company was used for the concrete surface finish. However, after one year, surface deterioration began, and it became rough. When we proposed the Seal Hard SKP specification to the design team at NiX JAPAN, they decided to take action before significant deterioration progressed, and we proceeded with the construction. Since the area from the entrance fence to the first joint was left unconstructed, it allows for comparison and observation between the constructed and unconstructed areas. Although only one year had passed since its opening, the surface has been finished to a quality exceeding that of the original construction!
