Ground reinforcement work | Completely avoid excessive design with the GeoColumn method of ISO quality management.

Eliminate excessive design with a strict quality management system compliant with ISO standards! The GeoColumn method achieves both reliable support strength and cost optimization through objective data.

To achieve a high level of reliability and cost performance in ground reinforcement work, a strict quality management system and scientifically based rational design calculations are essential. The Geo-Column method is a highly reliable ground improvement technology that mechanically mixes and stirs locally generated soil with cement slurry to form strong soil-cement columnar improvements underground. Geotech Co., Ltd. has established a quality management system (QMS) based on ISO 9001, operating all processes from the analysis of ground survey data to design planning, site arrangements, and completion inspections under high transparency management. During construction, dedicated automatic management measurement devices are used to continuously record excavation depth, rotation torque, and slurry discharge volume in real-time, visualizing and proving the quality of the underground structures as objective numerical data. By preemptively eliminating unnecessary excessive design while ensuring reliable building support performance over a long period, we provide clients with significant peace of mind and a rational ground reinforcement solution.

basic information

The design specifications for the geocore method are a standard cross-sectional area of 0.283m² (φ600mm), with applicable ground being cohesive soil (settling on good ground with an N value over 3) and sandy soil (settling on good ground with an N value over 4). The design standard strength Fc is set between 400 and 1,500 kN/m² (with 600 to 800 kN/m² for general single-family homes). The standard amount of solidifying agent added is 300 kg/m³ or more for cohesive soil, 250 kg/m³ or more for sandy soil, and 350 kg/m³ or more for organic soil, with strict adherence to management standards compliant with ISO 9001 (measurement error within ±2%, management of water slurry specific gravity).

Applications/Examples of results

It is widely used for the foundation ground reinforcement of single-family homes, multi-family residences, and apartments, where reliable structural evidence and budget optimization are required. It is applied directly under strip foundations (with a standard column pitch of 910mm) and slab foundations (with average placement and concentrated placement under load-bearing walls), preventing eccentricity and settlement due to uneven building loads. Furthermore, it is utilized as a standard construction method by design offices and contractors who want to avoid excessive design, in addition to reinforcing the lower parts of corner and entry columns and through columns. It is ideal for sites that require reliable quality control based on substantiated numerical data.
