Ground reinforcement work | SMD method that completely prevents the settlement risk of cohesive soil layers with a sealing effect.

The Minister-approved SMD method prevents differential settlement accidents in weak, viscous soil using an open-type steel pipe and a special inner and outer wing for pipe internal blockage effects.

Ground reinforcement work is a foundational technology designed to prevent uneven settlement of buildings on weak ground and clay layers, ensuring structural safety over an extended period. Particularly when constructing buildings on thick clay layers containing moisture, neglecting appropriate reinforcement in advance can lead to distortions and defects in the structure due to consolidation settlement. The SMD pile method provided by Geotech Co., Ltd. is a Minister of Land, Infrastructure, Transport and Tourism certified rotary driven steel pipe pile method, equipped with special outer and inner wings at the tip of an open-type small-diameter steel pipe. During the rotary driving process, the inner wings capture soil into the pipe to prevent axial deviation, and upon completion of driving to the target depth, the captured soil completely seals off, creating a strong end bearing capacity. This ensures reliable support performance even on clayey ground (equivalent N value of 27 or lower), eliminating settlement risks from the structural foundation. Our company conducts detailed pre-analysis of soil data and automatic tracking using real-time torque management on-site, achieving high-quality ground reinforcement that objectively proves reliable bottoming through data.
