Ground reinforcement work Cross Wing Column Method [Performance Certification Method]

High-precision deep mixing method that has obtained GBRC performance certification.

This is a slurry-based mechanical mixing deep mixing treatment method that has obtained the Architectural Technical Performance Certification from the Japan Architecture Comprehensive Testing Institute (GBRC Performance Certification No. 12-17 Revision 1). It achieves extremely stable mixing performance with minimal variation, unaffected by soil type, thanks to a patented, uniquely developed mixing and stirring device. Numerous performance verification tests conducted on sandy soil, clay, and loam have demonstrated a reliable high quality with a coefficient of variation of 25% or less, providing highly reliable construction based on technical guidelines. Additionally, due to the small markup factor for quality control, excessive material usage can be suppressed, and strict quality inspections can be conducted at minimal cost by adopting "Inspection Method A" as a principle.
