The plans for a 150,000 square foot apartment complex included nine
3- to 4-story wood-framed residential dwellings over 1 story concrete
podium parking structures. Loose saturated sands and high seismic
design values presented foundation support challenges and liquefaction
susceptibility. After considering earthquake drains, mat foundations,
and deep foundations (piles), the project team chose a verifiable and
cost-effective combination Geopier® solution, including the Geopier
Densipact™ system. Densipact densifies loose granular soil by repeatedly
driving a multi-tined tool into the ground using high frequency, vertical
impact energy and downward crowd force. Densipact created a densified
crust to reduce liquefaction settlement potential and provided an
increase in allowable bearing pressure for the column foundations.
