Earthquake Drains


The project consisted of an independent living apartment building, villas, and pavilion in Wilmington.

The Problem

The presence of liquefiable loose sand below the water table would produce 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.
