1．Company Basic Information

A subsidiary of Ozawa Sogyo, the No.1 concrete pump truck company in Tokyo.

Purchase and sales of used concrete pump trucks, development and sales of concrete related products.

Development, sales, and construction of Dotcon.

Having been involved in concrete for many years, the company has focused on concrete-related issues and has developed and sold numerous products that overturn common industry practice, such as the environmentally friendly Ecosul advance material and the Angel’s Wing and Devil’s Wing, which agitate ready-mixed concrete without wasting.

2．Product Information

Product: Dotcon

Dotcon,” a water-permeable concrete casting panel, was developed based on the concept of “a future without flood damage.

This product is expected to be used not only for water permeability but also for various other purposes, while maintaining the advantages of concrete.

A φ65mm sleeve is installed at 18 places per 90cm*90cm (0.81m2).

Through these sleeves, rainwater infiltrates into the roadbed and roadbed, and is recharged underground.

The sleeves are connected to each other by a channel, which allows rainwater to be stored and infiltrated into the ground even during heavy rainfall.

Dotcon panels are made of recycled polypropylene.

The construction method is similar to that of ordinary concrete pavement, and no special construction equipment is required.

Tests have shown that the surface temperature is on average 1.2 degrees Celsius lower during the daytime and 2.4 degrees Celsius lower at night than that of ordinary concrete, thus contributing to heat island countermeasures. (Test results by the Better Living Foundation)

This is the world’s only horizontal construction method that does not require a water slope.

It can be used not only for parking lots, but also for various other applications such as slopes and standard river surfaces.

It is also attracting attention from around the world. The presidential aide of the Democratic Republic of Congo came to inspect it and plans to adopt it in an ODA project.

It has also attracted attention from the governments of the Republic of Indonesia and South Korea, which are planning to install it.

Concrete foaming agent is widely used in lightweight partition boards, CLC blocks, backfill, etc.

4．Product Features

• Permeability

The water permeability of the system allows rainwater to permeate even in heavy rainfall, which helps prevent flooding and eliminates the need for water gradients. Each panel can store 14 liters of water, so it can also be used for water storage purposes.

• Heat island measures

Tests have shown that the surface temperature is on average 1.2 degrees Celsius lower during the daytime and 2.4 degrees Celsius lower at night than that of ordinary concrete, thus contributing to heat island countermeasures. (Test results by the Better Living Foundation)

• Use for infrastructure

The material can be used for slopes and river beds. On slopes, the holes have advantages such as allowing water to drain in and out and earth anchors to be driven in. Use in river beds can be expected to improve water quality and the propagation of animals and plants.
