You can choose a surface treatment method that corresponds to the construction purpose and surrounding environment! We will introduce our ground reinforcement soil engineering methods.
We would like to introduce the "Soil Nailing Method" and "High-Spec Nailing Method" of San Shin Construction Industry's ground reinforcement soil engineering techniques. The Soil Nailing Method is a technology that has developed as a design approach suited to the realities of our country, with over 570 projects and a construction area exceeding 260,000 m² in Japan to date. Additionally, the High-Spec Nailing Method is a ground reinforcement soil engineering technique that reliably creates reinforcement materials with significant resistance within the ground by using a core material equipped with a bag-type reinforcement (HSN packer). 【Features of the Soil Nailing Method】 ■ Efficiently constructs stable retaining walls (earth pressure resisting structures) ■ Allows for reverse construction, enabling safer operations ■ High adaptability to deformation and excellent seismic performance ■ Capable of adjusting reinforcement material placement in response to changes in ground conditions during construction ■ Generates minimal noise and vibration during construction, making it easy to work in narrow spaces and steep slopes ■ Applicable as a reinforcement method for existing structures *For more details, please refer to the PDF document or feel free to contact us.

basic information
【High-Spec Nailing Method Features】 ■ Grout does not deviate even in gravel ground, allowing for reliable grout injection. ■ Construction can be performed using small machinery, similar to conventional nailing methods. ■ The large pull-out resistance allows for shorter reinforcement lengths, eliminating the need for a wide backfill area. ■ A surface treatment method suitable for the construction purpose can be selected, making it applicable as a reinforcement method for existing structures. *For more details, please refer to the PDF document or feel free to contact us.
