Ground reinforcement work | Achieving environmental conservation and cost reduction with the no-dumping ETP method.

The ETP method achieves zero generation of residual soil and low noise and low vibration construction. It prevents soil contamination without using cement, contributing to reduced disposal costs on-site and shortened construction periods.

This document introduces the overview of the "ETP method," the definitive solution for "ground reinforcement work" that enables significant cost reduction and consideration for the site environment through no soil displacement and low noise construction. In urban areas and densely populated residential areas, ground improvement not only addresses building differential settlement but also faces major challenges such as noise and vibration during construction, inflated costs for construction waste disposal, and the risk of soil contamination from cement. The ETP method is a no-soil-displacement rotary-driven steel pipe pile method that uses a steel pipe with a disc wing and drilling assist bit attached to the tip. Since it does not use cement milk, there is no generation of surplus soil or industrial waste, dramatically reducing disposal costs and the hassle of truck transport. Additionally, it allows for low noise and low vibration construction with compact machinery, minimizing the impact on neighboring areas. With a total of 16 sizes ranging from a pile diameter of φ89.1mm to φ609.6mm, it boasts excellent sustainability, allowing for easy removal and recovery of piles in reverse rotation during future building demolition. Under the strict quality control of Geotech Co., Ltd., it provides ground reinforcement that balances environmental conservation and economic efficiency.
