Introduction to Dotcom Plus

A groundbreaking permeable paving material has emerged from Pump Man, a company based in Akiruno, Tokyo. Following the success of their original product, Dotcom, which was renowned for its high permeability due to its unique structure of circular holes, Dotcom Plus has taken the concept of permeable concrete to new heights. This innovative product not only addresses the limitations of its predecessor but also introduces a host of impressive features designed for various urban landscapes.

Evolution of Dotcom: The Birth of Dotcom Plus

While the initial Dotcom product was widely supported for its innovative design and features like high permeability and horizontal performance, it had its weaknesses. There were safety concerns for pedestrians using high heels or walking sticks, and a range of design preferences among users. Additionally, it had a load-bearing capacity limited to 6 tons, which restricted its application in certain scenarios. Dotcom Plus is designed to eliminate these issues, making it the ultimate paving solution and a “dream structure” for urban planners and construction engineers alike.

Key Features and Innovations of Dotcom Plus

1. Versatile Design Options: The standard pattern is a 600mm square, beautifully segmented by 1cm widths. There are also options for rectangular and hexagonal designs, allowing for diverse applications in various settings.

2. Customized Strength and Thickness:
- 15cm Thick Type: This can support wheel loads of up to 10 tons, making it perfect for heavy vehicles like trucks.
- 10cm Thick Type: Ideal for residential areas, it does not require rebar for ordinary passenger cars, significantly reducing construction costs.

3. Monolithic Structure: The design eliminates the need for formworks and shrink joints, simplifying the construction process, reducing time, and cutting down costs.

4. Hybrid Structure for Water Retention: The top layer features a 1cm gap to direct water downward in a V-shape, creating storage within the material. It mimics the functionality of rainwater infiltration systems and qualifies for various governmental subsidies.

5. Level Installation Without Water Gradient: Unlike traditional permeable systems that require sloping, Dotcom Plus achieves a completely level structure. This innovation enhances design flexibility while contributing to aesthetic and safety improvements.

6. Maintenance Access via Slits: Should the structure become clogged, maintenance can be performed through the 1cm slits, ensuring long-lasting permeability and performance. This feature is a significant advancement in permeable paving technology.

Global Attention Before Launch

The product is set to garner international interest even before its official launch:

• - A trial installation and unveiling event is scheduled for mid-July 2025 in Akiruno, Tokyo.
• - Sales are planned to begin on September 1, 2025.
• - In Jeddah, Saudi Arabia, a collaboration with a local subsidiary and a plumbing organization will see Dotcom Plus installed at the Sheraton Hotel, showcasing its global potential.
• - In Thailand, inquiries are underway from major trading companies, while in Africa, it offers solutions for malaria prevention by addressing ineffective drainage systems.

Supporting a Sustainable Future

Dotcom Plus represents an infrastructure product tailored for urban flood control, water resource conservation, and malaria mitigation, all vital for sustainable cities. Recognized by the Tokyo Metropolitan Government as a “Rainwater Infiltration Ambassador” (No. 6), it has received accolades for its potential to deliver cost-effective stormwater control similar to large-scale hydraulic systems.

Future Developments

• - The product will feature prominently in the upcoming TIGAD-9 exhibition in Yokohama.
• - Requests and inquiries from countries worldwide are growing rapidly.
• - Dotcom Plus is quickly gaining prominence as a leading example of next-generation permeable paving originating from Japan.
