toukon soil

Soil that makes green

Patent No. 4989332

Ideal for when you want green, but the grass grows long and difficult to maintain.
The growth of grass can be controlled to 2 cm or 3 cm.
* If you want to strengthen the growth of plants, you can create different types.

4features

Landscape that matches nature
Since the fine roots of the turf enter the soil, the soil and the turf adhere to each other.

Weeds are hard to grow
Many roots of weeds grow vertically, but turf has the characteristic of rooting left and right.
By taking advantage of this feature, turf grows, but weeds become harder to grow.

Also on concrete
If the construction site is concrete, etc., installing a formwork will create a green space on the concrete.
(Refer to the construction procedure below)

For controlling landslides
By hardening with toukon soil, it becomes an environment where moles and weeds with strong roots (mugwort, dandelion) that cause landslides cannot grow.
By taking advantage of this feature, turf grows, but weeds become harder to grow.

Focusing on the fact that the plant height and root length grow at a constant ratio in the process of plant growth, we try to suppress the growth of the plant by limiting the root area of the plant. We will limit the root area by burying "toukon soil" in the place where we want to green.
Since this permeable soil layer has water permeability and water retention, it does not inhibit the growth of plants, and its main feature is that it is compatible with plants because its main component is a natural material. Furthermore, by forming a strong layer of transparent lump soil, it is possible to prevent the germination of weed seeds flying from the outside and the pushing up of weeds from below.
