Since the block itself has a thickness of 350mm, it is a type of block that does not require core concrete. As hydraulic characteristic values have been obtained, it is possible to consider flow velocity. This contributes to the creation of resilient riverbank protection. Process -54% contributes to labor saving! Since there is no need for core concrete placement and the product is large at 1.0m2 per unit, it allows for machine construction and contributes to labor saving. The process can be significantly shortened by -54%.

The Wide Wall Method is a road widening system that is completed simultaneously with the stacking of blocks. It involves using trapezoidal blocks on top of large blocks to achieve road widening. Similar to the conventional construction of large stacked blocks, road widening can be accomplished simply by "stacking blocks," allowing for a maximum road widening of approximately 2.0 meters with three layers of Wide Wall blocks. It is ideal for the installation of pull-off areas, bus stops, and sidewalks in mountainous regions where full two-lane conversion is difficult! <Received the 11th National Land Technology Development Award "Regional Contribution Technology Award">

• Stacking blocks

The "CV Block" is a block that takes into consideration the points of caution regarding the revetment blocks in the "Basic Policy for Disaster Recovery to Protect Beautiful Mountains and Rivers." Due to the surface irregularities of the block material, the concrete surface is coarse, featuring a traditional fabric-like pattern, and by staggering the vertical joints, individual blocks are made less noticeable. The size of the patterns on the block surface is based on traditional stone masonry sizes, making it feel familiar in relation to the human body size. 【Features】 ■ Sizes: 2.0m² / 1.0m² / 0.5m² / 0.25m² ■ Brightness certification obtained ■ The surface irregularities result in a coarse concrete surface ■ As it is a large block designed with consideration for the integrity with the embedded concrete, it can be used even in rivers with high flow rates ■ With a control length of 350mm, design calculations are unnecessary, simplifying procedures and reducing construction time *For more details, please refer to the PDF materials or feel free to contact us.
