MAT Inc. (Headquarters: Midori-ku, Nagoya City, Representatives: Takayoshi Yoshikawa / Yoichi Kondo), a specialized manufacturer of decorative concrete paving materials, has implemented floor surface construction using its flagship product 'Mat Spray' in a park improvement project commissioned by Kuki City, Saitama Prefecture.
This construction was handled by Okazaki Kenso Co., Ltd., a certified partner of MAT Inc., and through their reliable construction techniques and abundant field experience, they achieved a high-quality finish down to the finest details.

■ Background and Challenges of the Construction
The park in Kuki City, Saitama Prefecture, had aged over the years since its installation. The existing concrete showed deterioration such as cracks, and water leaks from the fountain were occurring. Furthermore, as an aspect of environmental improvement of the park accompanying residential development, harmony with the surrounding environment and improvement of aesthetics were increasingly demanded.
Therefore, a fundamental improvement including the renewal of the existing concrete, rather than just a simple surface repair, was required. Instead of 'construction making use of existing concrete', which is a feature of Mat Spray, new concrete was cast to restore the base function, and Mat Spray was applied as the finishing touch.
While the new concrete itself could serve as a finish, a highly decorative finish that emphasized improving the park's aesthetics and harmonizing with the surrounding environment was sought. In addition, as a public works project, there were strict constraints on the construction timing and period, and under these conditions, short-term construction over a vast area was necessary.
■ Background of Adopting Mat Spray
Under these conditions, Mat Spray was adopted for the following reasons:
- A large area can be constructed per day, making it suitable for extensive application.
- It enables short-term construction, suitable for public works with strict period constraints.
- Highly design-oriented, contributing to the improvement of park aesthetics.
Before construction / After construction
Furthermore, prior to construction, the completed image was shared using a prepared photo simulation (Before/After images). Thanks to this, we received high praise in advance from city officials and related parties, saying things like, 'It is very easy to understand, and gives a bright and good impression.'

■ Construction Overview
Location: Minamikurihashi Neighborhood Park, Kuki City, Saitama Prefecture
Project Type: Public works
Construction Part: Park floor surface
Construction Area: Approx. 1950 sqm
Construction Period: February 2, 2026 - March 21, 2026
Construction Method: Formwork spray paving method
■ Features of Mat Spray
Mat Spray is Japan's only decorative paving method that can be applied without destroying existing floors.
1. Eliminates the need to remove existing floors, significantly reducing cost and construction time.
2. Provides a non-slip effect, improving safety for park users.
3. Achieves a highly aesthetic finish by combining stencil joints and colors.
4. All materials are manufactured in the group's own domestic factory, ensuring stable quality.
It is adopted in a wide range of scenes such as public facilities, commercial facilities, detached houses, hospitals, and nursing care facilities. Construction on asphalt pavement is also possible (using a proprietary special adhesive), realizing low-cost and short-term renovation.
■ Key Points of Construction
Mat Spray is a construction method that can express a variety of designs, such as stone pavement and brick styles, by attaching stencil joints and spraying paint with a dedicated hopper gun. A uniform finish is obtained with a spraying thickness of 1.5 to 2 mm, and it is usually completed in about 2 to 3 days (approx. 50 sqm / 2 parking spaces), achieving a high-quality finish in a short period. Because it can handle large-scale construction, efficient construction became possible even for large-scale park maintenance like this one.
■ Evaluation After Construction
Just as it was highly evaluated in the preliminary photo simulation, many comments were received regarding the actual finish, saying 'The real thing is definitely excellent', resulting in extremely high praise for the aesthetics after completion.
