County Line, Hialeah, Florida
Constructed in four phases over a seven-year timeframe beginning in 2016, the 450-acre County Line site in Hialeah, Florida has become a major industrial hub in South Florida as a home to over two dozen warehouses. Decades of uncontrolled dumping left the majority of the site covered with about 15 feet of municipal solid waste (MSW) landfill material sitting on top of limestone bedrock. To facilitate a shallow foundation system for the proposed buildings, a robust dynamic compaction program was implemented across the entirety of the site in various phases. Following completion of the work, a three-foot thick soil mat was established across the surface to provide a cushion for the foundation and slab-on-grade system.
Cold Stream Redevelopment, Truckee, California
Sitting in the shadows of Donner Pass in scenic Truckee, California, the Cold Stream Redevelopment project consisted of a multi-phase effort to redevelop a former quarrying site into a thriving residential community. Split into multiple phases over two years, the dynamic compaction efforts undertaken at the Cold Stream site encompassed 20 acres of improvement area, all of which was calibrated to a detailed test program carried out at the onset of the project. Specifically, uncontrolled fills at the site were improved to provide both the required allowable bearing pressures for the proposed structures, but also to provide a level of compaction to mitigate against seismically-induced settlements at depth.

Bahia Beach Resort, Bahia Beach, Puerto Rico
Completed in 2021, Densification, Inc. improved loose sands underlying 32 beachfront lots to assist in mitigating against potential liquefaction concerns prior to the development of high-end residential structures. Utilizing one of our newer Liebherr LS8100 crawler cranes, we were able to deploy a 20-ton weight from an 80-foot drop height to deliver the energy level necessary to improve the liquefiable soils underlying the site. Once ground improvement was completed at the site, the residential structures were supported on shallow foundations designed using an allowable bearing pressure of 4,000 pounds per square foot.
Tempe Business Park, Tempe, Arizona
The Tempe Marketplace property was historically used as a Municipal Solid Waste (MSW) and construction debris landfill for decades prior to the late 1990s. In 2015, the site was targeted for redevelopment as a thriving commercial and retail destination within Tempe. In order to stabilize the over 40 feet of highly variable landfill material underlying the site, a dynamic compaction program was conducted across the entire development footprint. In areas to receive vertical construction, additional high-energy passes were completed to provide additional strengthening to the on-site soils. Following dynamic compaction, the new construction at the site was supported utilizing shallow foundation systems in conjunction with slab-on-grade construction.

Bridge Point Commerce Center, Miami Gardens, Florida
As part of the ongoing e-commerce boom across the country, large-scale distribution facilities have become more critical from a supply chain standpoint. At the same time, the amount of suitable, ready-to-build sites are dwindling as development increases. In the case of the Bridge Point Commerce Center in Miami Gardens, Florida, these two issues collided, resulting in the need to construct high-end warehouse structures with substantial floor loads on a site underlain by approximately 25 feet of municipal solid waste (MSW) landfill material.
In 2021, a two-phased ground improvement approach was developed for the 80-acre site to address the significant geotechnical challenges. First, a dynamic compaction program was conducted across the entirety of the site to stabilize all paved areas as well as building pad locations. Following dynamic compaction, a rigid inclusion program was implemented by others in the building footprints to provide additional foundation support.
Flight 93 Memorial, Shanksville, Pennsylvania
Following one of the darkest days in American history, memorials were dedicated throughout New York, Pennsylvania and Washington, DC in remembrance of 9/11. In Shanksville, Pennsylvania, improvement of historic mine spoil materials was necessary to stabilize the foundation bearing soils for the Flight 93 Memorial, which was constructed to honor the heroes who lost their lives on that flight. Densification, Inc. was honored to have played a small role in such a significant project for the region and our country.

Prudential Center, Newark, New Jersey
Opened in October 2007, “The Rock”, as it’s known locally, was constructed on a shallow foundation system following the completion of a comprehensive ground improvement program. Thirteen acres of urban fill was improved by Densification, Inc. using dynamic compaction, which was an aggressive program, given the sensitive urban environment where the arena was to be constructed. However, the dynamic compaction program was highly successful, even allowing the design team to increase the design allowable bearing pressure from 2 to 3 tons per square foot.
JFK Airport, Queens, New York
As a result of upgraded seismic design considerations in the New York City Building Code, a more advanced site-specific seismic study revealed that a ground improvement program could be implemented to mitigate liquefaction concerns for a proposed 80,000 square foot Northwest Airlines cargo hangar expansion at the airport. Densification, Inc. was retained to implement a dynamic compaction program to improve the upper 20 feet of loose sands at the site; this allowed for shallow foundation construction, saving millions of dollars in driven pile foundation costs.

Dell Center, Oklahoma City, Oklahoma
Utilizing four cranes to meet a highly aggressive construction schedule, Densification, Inc. provided dynamic compaction services to improve over 2.2 million square feet of improvement of historic construction demolition material to facilitate the construction of a new Dell Call Center. Construction of the facility was a major victory for Oklahoma City, following a lengthy courting process with Dell, and Densification, Inc. was part of the team that made the project a reality. Today, the facility employs over 1,500 local residents.
Northside Generating Station, Jacksonville, Florida
In an effort to increase the efficiency and reduce emissions at the existing JEA Northside Generating Station, a significant modification process was undertaken beginning in 1999. As part of the plant upgrades, two new coke storage domes were constructed; however, given the loose sands underlying the structures, a significant dynamic compaction program was conducted by Densification, Inc. to improve approximately 435,000 square feet of footprint to mitigate against damaging post-construction settlements.

CityPlace, Palm Beach, Florida
Opened in 2000, CityPlace began an urban renewal of a formerly crime-riddled area of Palm Beach, Florida, and is now the premier retail complex in the area. In order to improve the 25 feet of loose sands that covered the site and allow for shallow foundation construction, a dynamic compaction program over several hundred thousand square feet was implemented by Densification, Inc. The program included two cranes and several different size weights in order to optimize the program and achieve aggressive design bearing pressures for the project, saving a significant amount of money. The adjacent Kravis Center for Performing Arts was improved using dynamic compaction several years prior to this undertaking.
Cypress Lakes Development Levee Improvement, Bethel Island, California
Completed in 2001, Densification, Inc. was contracted to perform a dynamic compaction program to improve potentially liquefiable soils beneath a proposed 4.5 mile-long dry-land levee in Bethel Island, California. The levee was being constructed to provide flood protection to 1,300 new single family residences and an 18-hole golf course on the 685-acre Cypress Lakes site.
