A representative method that has created the history of ground improvement! Its application range is wide and utilized for various purposes.
We would like to introduce the land-based version of our rebound-type sand compaction pile method, "Composer." Using a vibrating hollow pipe, the "rebound construction" method repeatedly penetrates, extracts, and re-injects to create large, well-compacted sand piles in soft ground, thereby stabilizing the ground. This method was developed and put into practical use by our company, and it has been adopted in various parts of the world, with a construction record of 380,000 km of piles. 【Features】 ■ Wide range of applicable ground and improvement purposes ■ Highly reliable construction management and quality control ■ Ensured creation of composer piles ■ Excellent versatility ■ Effective utilization of construction by-products *For more details, please refer to the PDF materials or feel free to contact us.
