The Facts About Bi-Modulus Columns (BMC) That You Need to Know
Bi-modulus columns (BMC) is a ground improvement technique that reinforces the soil by a combination of CMC and stone columns.
The Bi-Modulus Columns (BMC) are vertical ground improvement elements composed of a rigid inclusion topped with a compacted granular column. BMC combine the advantages of Controlled Modulus Columns (CMC) and Stone Columns, so the upper soil is not over-stiffened and is more compliant in areas with high seismicity. BMC result in an increased bearing capacity, a reduction of total and differential settlements as well as improved stress distribution from the structure to the inclusions which leads to an optimization of the thickness of the load transfer platform (LTP) between the structure and the inclusions.
To date, Menard has successfully carried out numerous projects using BMC method. BMC are particularly effective in cases of deep cut-off, to avoid unwanted moments in slabs on backfill or in a seismic zone. All these factors have generated exponential growth in the use of the BMC technique since it was developed.
