Overcoming liquefaction! We will improve the ground from liquefied soil to non-liquefied soil.
The static pressure grouting method "Compaction Grouting" improves the ground from liquefied to non-liquefied soil. It is a technology that injects a mortar with extremely low fluidity (slump of 5 cm or less) into the ground without applying any vibration or impact. The injected mortar, due to its low fluidity, solidifies in the designated position without escaping. This solid mass compresses the surrounding soil and increases its density. 【Features】 ○ Static pressure grouting ○ Compression reinforcement of surrounding soil ○ Compact equipment ○ Suitable for hard ground ○ Improvement rate can be selected according to soil layers For more details, please contact us or download the catalog.

basic information
【Application Examples】 ○ Easy construction on existing structures → No issues such as large construction machinery, vibrations, noise, or impact on surrounding areas → Excellent effectiveness in protecting existing structures and buried objects ○ Behind the quay wall → Prevents the pushing out of caissons by improving the liquefied layer behind the wall ○ Under the runway → Prevents sinking by improving the liquefied layer beneath the runway ○ Under the oil storage tank → Prevents ground subsidence by improving the liquefied layer beneath the oil storage tank ○ Embankment structures (narrow or adjacent areas) → Prevents sinking and collapse of the embankment layer by improving the liquefied layer ● For more details, please contact us or download the catalog.

Company information
The CPG Method Research Association was established in February 2003 with the aim of promoting the CPG method and improving technology for the healthy development of the method. We conduct research and investigations on the application and construction methods of this technique. Additionally, we have set up a consultation window for inquiries related to the CPG method, so please feel free to utilize it. To free our invaluable infrastructure from the threat of "liquefaction of the ground," we propose the "Static Pile Driving and Compaction Method (CPG Method)."
