Monteith Construction


Multifamily Residential


Earthquake Drains


The project consisted of three multifamily buildings for a senior living community in Mount Pleasant.

The Problem

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.
