South Bay Garden Flats
Mount Pleasant, South Carolina
The project consisted of three multifamily buildings for a senior living community in Mount Pleasant.
The presence of liquefiable loose sand below the water table would create structural damage during an earthquake.
Earth Tech Solution
Earth Tech proposed a ground improvement program consisting of Earthquake Drains on a four to six-foot triangular grid under the building footprint. Liquefaction was mitigated avoiding the need for a costly deep pile foundation system.
