KP large block

KP large block

Large blocks with good workability as the products stand independently when installed at slopes of 3, 4, and 5 degrees!

We would like to introduce the "KP Large Block" that we handle. The "Low Retaining Wall" type features protrusions on the product, while the "High Retaining Wall" type uses guide pins to prevent shifting and ensure stability. Additionally, since the back wall is integrated, there is no need for a backing formwork, allowing for effective pouring of ready-mixed concrete. 【Features】 ■ Improved workability with the installation of 2 blocks per square meter ■ The product stands independently during construction with 3:1, 4:1, and 5:1 slopes, enhancing workability ■ Using dedicated lifting equipment for the installation of decorative blocks ensures that the blocks can be installed reliably, easily, and safely, improving workability and safety ■ Natural stone surfaces are adopted to better match the natural environment *For more details, please refer to the PDF document or feel free to contact us.

Control towel free seismic-resistant large block "Guardian"

Control towel free seismic-resistant large block "Guardian"

We named it "Guardian" to watch over all the construction work.

The "Guardian," a large block with adjustable width and seismic resistance, is primarily used for roadside retaining wall construction. It allows for the width to be freely changed from 500 to over 3500 mm through connectors that link the front and back, and it can accommodate slope gradients from vertical walls to 1:10, including 1:1, 1:3, 1:4, and 1:5 slopes. Compared to conventional products, it is significantly lighter, making it possible to use small cranes for installation, even in narrow sites. This product meets the current challenges in construction sites, such as "labor shortages," "shortened construction periods," "cost reduction," and the demands for "workability, safety, and aesthetics." Additionally, while traditional products required separate molds for each width, the "Guardian" can be manufactured using just one mold for the front and one for the back, providing advantages for manufacturing companies as well.
