greenbiz Ground
that colors the ground and harmonizes with nature
greenbiz Ground is a pavement block made by molding granular microporous ceramics as aggregate to increase strength. The water retention capacity has been greatly improved to 1.5 times or more of the conventional water retention block. It has excellent water permeation performance and it is difficult for puddles to form, making it the perfect material for places where people gather.
Features of greenbiz Ground
with water spray effect
It has been recognized that it has plenty of rainwater and cools the road surface with a water spray effect. The difference is 5 ~ 20 ℃ compared to normal asphalt pavement. Contributes to alleviating the heat island phenomenon and creating a comfortable environment.
safe even in guerrilla heavy rain.
When laying Green Biz, water pools are less likely to occur due to its water absorption capacity.
Once the water has been absorbed, it is retained inside, and when it reaches the full saturated water content, it is allowed to permeate the roadbed and subgrade. The effect is exhibited in rainwater runoff control and permeable storage.
The air layer contained in the small holes in the aggregate functions as a heat insulating layer. Even in the freezing state confirmation test (-20 ° C), it has been confirmed that both the surface and the interior are hard to freeze and the frictional resistance is maintained. In addition, the freeze-thaw test has cleared 150 cycles (6 times the standard), and is also recommended in cold regions.

Maintanance
SJ-V method：Ultra-high pressure water (80-150MPa) is sprayed directly on the pavement surface with a dedicated cleaning unit.
・Functional recovery of permeable and water-retentive pavement
・Extensive washing with a small amount of water
・Recovery of slip resistance
・Restoration of landscape, removal of deposits such as gum and earth and sand
・Removal of weeds and moss growing from joints
・Abundant optional construction

Functional pavement Rainwater storage type
Japan’s first. Rainwater storage type pavement that eliminates rainwater runoff in open spaces and parking lots
Acquired technical evaluation certification of the Rainwater Storage and Infiltration Technology Association of Japan.
A system to control rainwater runoff and store and infiltrate rainwater on pavement surfaces
(Eco-block Biz method) and obtained evaluation certification.
By laying greenbiz Ground, parking lots and open spaces can be included in rainwater runoff control facilities.
