Densipact Ground Densification Technology in California.
Engineered ground densification for liquefiable soils and loose sands. A proven seismic mitigation tool for California projects.
Densipact is a ground densification technology that increases the relative density of granular soils across a treatment zone. By applying vibratory and impact energy to the soil mass, Densipact reorganizes loose particles into a denser, stronger, and more resistant configuration.
In California and other high-seismicity regions, loose saturated sands are vulnerable to liquefaction during strong ground shaking. Liquefaction can produce major settlement, lateral spreading, and loss of bearing capacity beneath structures. Densipact directly addresses this risk by raising the relative density of the treatment zone above the threshold at which liquefaction is expected.
On the right site, Densipact is a highly cost-effective alternative to deep foundations. It is widely specified for commercial and industrial buildings, tank foundations, transportation infrastructure, and seismic retrofit work where liquefaction mitigation is the governing design issue.
WGI evaluates the geotechnical report, planned loads, and seismic demands for each project and confirms the appropriate treatment depth, spacing, and verification program.
Frequently Asked Questions

Liquefaction occurs when loose saturated sandy soils temporarily lose strength during strong ground shaking and behave like a liquid. California has many sites with loose granular soils and high seismic demand, so liquefaction is a leading design consideration for foundations and infrastructure across the state.
Densipact uses vibratory and impact energy to rearrange loose granular soils into a denser configuration. Higher relative density makes the soil far more resistant to the pore pressure buildup that drives liquefaction, dramatically reducing the risk and the consequences of a major seismic event.
Tank foundations, port facilities, transportation infrastructure, commercial and industrial buildings, and seismic retrofit projects on sites with loose saturated sands. WGI reviews the geotechnical liquefaction analysis and confirms whether Densipact is the most efficient mitigation strategy.
