Eco-friendly Block

We will stand at the forefront of environmental conservation with our technologies blending harmoniously with the nature.

Eco-friendly Cheongra building block

Eco-friendly Cheongra building block was designed to be built on the slop of roads or on the wall of embankment maintaining the revetment of river to facilitate adherence of plants. It provides excellent vegetation function, blending well with surrounding scenery and also has excellent structural stability. So, this block is used widely for prevention of soil loss.

Features

1. Structural stability improved by fixed support
- The rear end of the product fixed is assembled with fixed support of length which varies depending on the upper, middle and lower part of the product to prevent forward overturning caused to hydraulic pressure or soil pressure.

2. Joggled lap joint ensuring greater connection force and prevention of loss
- The uneven part on the side of the product allows the integration of blocks, thus preventing dislocation of blocks.

3. Prefabricated structure for greater convenience in construction
- It allows simplification of construction by using construction equipment. So, it shortens the construction period and reduces costs such as labor cost.

4. Harmony with the surrounding landscape
- The opened part allows the rainwater to pass, facilitating creation of vegetation space inside the product and ensuring excellent harmony with surrounding landscape.
