SoilFreeze is the only U.S. construction company specializing exclusively in ground freezing services for construction and related industries. The company provides structural shoring, groundwater cutoff, and soil contamination remediation through an innovative ground freezing technique that is more environmentally friendly, lower cost, and saves time compared to other shoring and groundwater cutoff techniques. The technique is demanding, however, and requires extremely reliable, durable refrigeration systems. Since its founding in 1998, SoilFreeze has relied on chillers manufactured by Technical Systems, Inc. (TSI), a division of RAE Corporation, to meet its precise refrigeration needs.
