Ground reinforcement work | A technical system that reliably reinforces various ground types using the CWC method.
Ground reinforcement work
Flexible response to complex ground conditions! The CWC method can handle sandy soils to clay and loam layers, allowing for the free selection of construction machinery and improvement specifications.
In ground reinforcement work at construction sites with complex ground conditions and many restrictions, flexible construction adaptability and advanced adaptability performance are required. The Cross Wing Column Method (CWC Method) developed by Geotech Co., Ltd. is a slurry-type mechanical mixing deep mixing treatment method that can adapt to a wide range of ground conditions, from sandy soil to clay and loam layers. Its unique intersecting six-blade mixing wings efficiently and forcibly mix the site soil and solidifying agents, forming a uniform and high-quality improved body that is not affected by differences in soil quality. Additionally, it allows for the selection of construction machinery ranging from small to large (10-ton class, 15-ton class, etc.) and automated plants according to site conditions, enabling optimal construction tailored to the site environment from narrow plots to vast areas. Furthermore, the management engineer certification system overseen by a method association of six developing companies and a strict QMS system ensure high standards of quality and safety at construction sites. This is a ground reinforcement technology that boasts reliable results in diverse projects. Please feel free to consult or inquire with us.

basic information
The specifications of the CWC method (Deep Mixing Method) apply to sandy soils, clayey soils, and loam layers. The improvement types include pile types (pile arrangement, circular arrangement, lap arrangement), block types, and wall types, accommodating various structures. The drilling rod is single-axis, with the number of blade cuts being 450 cuts/m or more for sandy and clayey soils, and 550 cuts/m or more for loam layers. The construction speed is based on a lifting speed of 1.5 m/min or less, and the water-solidifying material ratio is set at 60-100% (sandy soil) and 60-80% (clayey soil and loam). It is an advanced technology boasting extensive support performance.

Applications/Examples of results
This construction method is utilized for a very wide range of target structures, from wooden and reinforced concrete single-family homes to apartment buildings, general buildings subjected to high loads, retaining walls, various structures, and foundations for transmission towers. It enables reliable ground integration even in sites where weak soil layers are deeply distributed or in complex geological conditions where sandy soil, clay, and loam are mixed. Additionally, it is highly regarded for construction in narrow sites with nearby structures and as an environmentally considerate construction method in densely populated residential areas with strict noise and vibration restrictions, making it applicable in various practical fields of construction.
