Dynamic Compaction Solutions (DCS) successfully delivered an efficient ground improvement program for a 74-acre data center site development. Faced with undocumented fill and soft clay deposits prone to excessive settlement and collapse, DCS implemented High Energy Impact Compaction (HEIC) to prepare the site for foundation slab-on-grade and pavement construction.
Why HEIC?
HEIC was chosen over conventional over-excavation as the most effective method for stabilizing the vast site while meeting a rigorous construction schedule:
Significant Cost Efficiency: HEIC proved to be 60% more cost-effective than traditional over-excavation and replacement methods.
Rapid Project Delivery: The program was completed 4x faster than conventional alternatives, saving the client four weeks of critical project time.
Superior Risk Mitigation: The process achieved up to 16 feet depth of influence, significantly outperforming the 4-foot limit of the proposed over-excavation alternative in reducing differential settlement risk at depth.
Proven Densification: Post-treatment data confirmed that the upper soil layers became 20% to 45% denser, with correlated N-values increasing by up to 110%.
By utilizing HEIC, DCS ensured the site was sufficiently densified to support conventional spread footings and meet all geotechnical recommendations. This project highlights DCS’s ability to deliver high-performance ground improvement that drastically reduces both budgets and timelines for large-scale industrial developments.

A highly contaminated site with Asbestos Containing Materials (ACM) was stabilized using in-situ High Energy Impact Compaction (HEIC), followed by the placement of an orange geofabric barrier and a 20-inch cap of clean Virgin Excavated Natural Material (VENM) for safety and compliance.
The site, initially covering 1,399,308ft², was contaminated with heavy metals including lead, zinc, and arsenic. It underwent in-situ compaction using High Energy Impact Compaction (HEIC) as a remediation strategy. Following treatment, the area was expanded to 1,614,578ft², capped, and repurposed for industrial use.
A specialised cell was constructed to contain Per-and Poly Fluoroalkyl Substances (PFAS)-contaminated soils, which were compacted on-site. This containment is crucial due to the persistence, environmental prevalence, and significant health impacts of PFAS contaminants.
A heavily contaminated 8,611,131ft² site with ACM and heavy metals was rehabilitated using High Energy Impact Compaction (HEIC). After in-situ compaction and capping with approved materials, the site was transformed into a valuable industrial asset and sold to the client.
