The "Bontoran Method" is a technique that allows for the recycling of ground materials by improving soft soil on-site, adding functions such as earthquake resistance. It does not require special equipment; improvement can be achieved simply by attaching a mixing attachment to an excavator. In the "Hamao District Embankment Construction," soft sludge-like soil was generated within a retention basin, and after considering recycling methods, this technique was adopted, leading to the completion of the river embankment in December 2002. There are various other construction examples, including the "Haga Pond District Development Project" and the "Torigo District Road Improvement Project." 【Construction Examples】 ■ Hamao District Embankment Construction (2002) ■ Improvement of National Route 458 (Agricultural Road Culvert) ■ Haga Pond District Development Project ■ Oami Central District Wide-Area Agricultural Land Development Project, Section 1 ■ Torigo District Road Improvement Project ■ Ichinichiya District and other embankment projects *For more details, please refer to the PDF document or feel free to contact us.

The "Bontelan Method" is a construction technique that improves the handling properties, durability, and earthquake resistance of soil that has traditionally been deemed unsuitable for use as fill. This is achieved by mixing fiber-based soil improvement materials called "Bonfiber" and solidifying agents into the soil. It is an environmentally friendly method that aims to enhance the quality of sludge generated during construction and repurpose it as excellent soil for reuse. The effectiveness of Bontelan improved soil as a ground material for earthquake resistance was demonstrated, as no damage was reported in civil engineering structures using this method during the Great East Japan Earthquake. **Features** - Significant cost reduction compared to conventional methods - Reusable as highly durable improved soil - Contributes to rapid disaster recovery - NETIS registration, registration number TH-020042-V - Collaborative research results from industry-academia-government → Professor Hiroshi Takahashi, Graduate School of Environmental Studies, Tohoku University For more details, please contact us or download the catalog.
