Ground reinforcement using the Σ-i method for logistics warehouses | Geotech
We achieve ground reinforcement that supports the floor load resistance of logistics warehouses through reliable support capacity calculations based on survey data.
In the construction of logistics warehouses, a high floor load-bearing capacity that can withstand heavy cargo and the passage of large vehicles is required. If the ground strength is insufficient, uneven settlement may occur, leading to issues such as floor surface tilting and structural distortion. Therefore, it is essential to accurately assess ground investigation data and implement ground reinforcement to ensure appropriate bearing capacity. Geotech's Σ-i method adopts a rational design approach that directly calculates allowable bearing capacity from the results of SWS tests and dynamic cone penetration tests, supporting the structural safety required for logistics warehouses. 【Usage Scenarios】 - Ground reinforcement for the flooring of logistics warehouses storing heavy items - Foundation reinforcement for facilities with frequent access by large vehicles - Designing new warehouses to reduce the risk of uneven settlement 【Benefits of Implementation】 - Securing bearing capacity based on clear technical evidence through calculations directly linked to investigation data - High transparency in construction quality through digital construction data management - Reducing on-site costs by minimizing construction-generated soil (excess soil) through the rotary press-in method
basic information
【Features】 - Direct calculation of allowable bearing capacity from the converted N values of SWS tests and ram soundings. - Technical specifications certified by the General Incorporated Foundation Japan Building Disaster Prevention Association (GBRC). - Excellent penetration thrust provided by the four excavation blades at the tip of the steel pipe and the integrally molded spiral wings. - Environmentally friendly construction method that does not generate construction waste (excess soil) due to the non-use of cement-based solidifying materials. - A lineup of shaft diameters ranging from φ89.1 mm to φ165.2 mm to accommodate various designs. 【Our Strengths】 Geotech is an engineering company that provides a one-stop service for all ground-related tasks, from ground surveys to reinforcement design and construction, settlement correction, and soil contamination investigations. With extensive experience and reliable technology, we support our clients' construction projects from the ground up.

Applications/Examples of results
This construction method is optimal for small-scale buildings such as single-family homes, multi-family residences, and stores that are three stories or fewer, have a height of 13 meters or less, and a total floor area of 1,500 square meters or less (for single-story buildings, 3,000 square meters or less). It also accommodates foundation reinforcement for retaining wall structures with a height of 3.5 meters or less. Because it allows for design calculations that are directly linked to ground investigation data such as SWS tests, it is widely used in sites where there is a desire for clear justification in building confirmation applications and structural calculations, as well as for rational and economical foundation reinforcement that minimizes excessive design.
