Ground reinforcement work | Optimizing the entire construction process with the DM method to achieve a shortened construction period.

Bolt connections that do not require on-site welding and rotary insertion construction that does not require curing. This eliminates the risk of delays in the process and enables speedy ground reinforcement work.

The "DM Method (Double Metal Method)" developed by Geotech Co., Ltd. is a small-diameter steel pipe pile ground reinforcement method that achieves a dramatic improvement in construction speed and compression of construction periods. In ground reinforcement work to prevent building settlement accidents, this method employs a unique structure that fixes ductile cast iron tip wings with bolts on-site, reducing construction time and waiting time associated with traditional welding work. Additionally, because it uses a rotary penetration method that does not require cement, there is no curing time needed, allowing for immediate transition to the next process after completion of the pouring. The use of a no-dirt construction method that generates no residual soil and compact construction machinery enables efficient work even in narrow sites. It has obtained the GBRC performance certification (No. 10-01) from the General Incorporated Foundation Japan Building Disaster Prevention Association, allowing for high-precision and speedy foundation design based on SWS test data. With a supply system for components from its own factory, rapid construction response from construction association members nationwide, and real-time construction data management, it provides high technical reliability and a reliable ground guarantee.
