Using ultra-compact construction machinery! This is a new concept in compaction methods that utilizes sand with added fluidity.
The "SAVE-SP Method" is a liquefaction countermeasure technique that uses ultra-small construction machinery to inject sand, which has been made pumpable, into the ground through a rod, thereby compacting the soil. It is possible to perform construction in narrow spaces and to compact the ground directly beneath existing structures. The sand, which has been mixed with a fluidizing agent and made pumpable (fluidized sand), is injected into the ground from the rod that has been driven to a specified depth, compacting the surrounding soil. The fluidity of the pumped sand disappears due to dewatering during discharge and the action of the added slow-acting plasticizer, forming good ground conditions. 【Features】 ■ Uses ultra-small construction machinery ■ Capable of liquefaction countermeasures directly beneath existing structures ■ Vibration-free and low noise ■ Excellent cost-effectiveness ■ Environmentally friendly construction method ■ October 2014, National Institute for Land and Infrastructure Management, Construction Technology Review Certificate No. 37 *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 - Construction is possible in narrow spaces and on piers due to the ultra-compact machine. - Easy to move, making it suitable for emergency evacuation at airports and other locations. - Capable of diagonal construction and penetration into hard obstacle layers. - Does not use a vibratory hammer like vibration-type SCP, allowing for quiet ground compaction. - Very economical compared to existing liquefaction countermeasures in narrow spaces or directly beneath existing structures. - Environmentally friendly by using ultra-compact construction machines and natural materials (sand), making it easy to integrate with the ground. *For more details, please refer to the PDF materials or feel free to contact us.
