四万十コンクリート Company Profile

We strive to become a company that grows together with the community by manufacturing and selling concrete secondary products that are in harmony with nature and considerate of the environment.

Shimanto Concrete Co., Ltd. is a company that manufactures and sells concrete secondary products at its factory in Shimancho, western Kochi Prefecture. The factory, located in the mountains, conducts manufacturing with consideration for the natural environment through the use of solar energy and other means. We handle various concrete secondary products, including the large block "Guardian," which won the Kochi Prefecture Local Industry Award this year for its adjustable width and seismic resistance, as well as the stone-faced block "Naturalock Shimanto" and porous concrete "Seiryu Shimanto." In particular, the "Guardian" allows for the width to be freely adjusted from 500 to over 3500 mm using fittings that connect the front and back blocks, making it significantly lighter than conventional products and enabling installation in narrow sites with small cranes. It is a product that contributes to shortening construction periods and reducing costs on job sites.
