EAZET has continuously improved product performance based on four concepts: high performance as a pile construction method, reliability based on a manufacturer responsibility construction system, compactness during construction, and environmental performance demanded by the times. Starting with pile construction in residential areas, urban areas, and narrow sites, it is actively used in various fields of architecture and civil engineering, including renovations of existing buildings, pile construction within factories and plants, elevator installations, the railway sector, telecommunications towers, seismic reinforcement, and seismic isolation methods. 【Contents】 ○ Introduction ○ Specifications of EAZET pile materials For more details, please contact us or download the catalog.

The ATT column, which started as a friction pile for soft ground, is increasingly being adopted as a point-bearing pile due to improvements in drilling capabilities through the introduction of high-torque machinery. By incorporating high-tensile steel pipe STKT590, the "bearing capacity of the pile material," which was often insufficient when used as a point-bearing pile, has significantly increased, enabling more economical foundation design compared to conventional ATT columns. 【Features】 ○ Exhibits large vertical and horizontal forces ○ Demonstrates high pull-out resistance For more details, please contact us or download the catalog.

• Ground foundation construction method

The ATT column is a hybrid pile that combines a highly reliable columnar improvement body with "winged steel pipes" that utilize the techniques of the screw pile EAZET method within the improvement body. By integrating the column and the winged steel pipes, it achieves a significant bearing capacity. This is particularly advantageous in cases where the supporting ground is deep, demonstrating excellent economic efficiency. 【Features】 ○ Exhibits large vertical and horizontal forces ○ Demonstrates high pull-out bearing capacity For more details, please contact us or download the catalog.

The Ultra Column Method is a mechanical mixing deep mixing treatment method that uses a cement-based solidifying material slurry. It employs a drilling head with a unique cross-shaped anti-rotation wing to reduce mixing failures caused by the soil's rotation phenomenon, which is problematic in viscous ground. Additionally, by measuring the resistivity of the column immediately after construction with a mixing tester, we can confirm the mixing condition and ensure the construction of high-quality columns. 【Features】 ○ Improved mixing efficiency with proprietary technology ○ Reliable quality control ○ A variety of improved forms available for selection For more details, please contact us or download the catalog.

The Rising Method is a ground improvement technique that involves placing pre-excavated soil into the excavation area and using a uniquely developed mixing bucket to mix the soil with slurry (W method) or soil with solidifying agents (D method), thereby constructing a highly homogeneous improved body of block-like consistency. 【Features】 ○ Ground conditions can be confirmed through pre-excavation ○ Mixing conditions can be investigated immediately after construction ○ Underground obstacles can be removed ○ A cubic shape allows for a 100% improvement rate For more details, please contact us or download the catalog.
