Sevenson Environmental Services has decades of experience applying solidification and stabilization (S/S) technologies to safely manage and treat contaminated materials. By combining innovative methods with state-of-the-art equipment, we deliver solutions that meet stringent regulatory requirements while protecting communities and the environment.
Experienced using a variety of reagents to meet treatment requirements
For over 40 years, Sevenson has been a respected industry provider of solidification and stabilization services, executing remediation work at former Superfund, manufactured gas plant (MGP), and contaminated waterway sites throughout the United States. Sevenson implements both in-situ and ex-situ solidification and stabilization using traditional and customized equipment, including excavators, pugmills, rotary attachments and caisson/auger soil mixing units.
Sevenson routinely updates its fleet of state-of-the-art in-situ solidification/stabilization (ISS) resources, supplementing the company’s inventory of heavy civil and marine construction, excavation, and dredging equipment. Recent equipment acquisitions include two BAUER Gruppe GmbH BG 45 BS 9 Premium Line rotary drilling rigs; one RTG 27S drilling rig; one RTG 22S drill rig; and five automated 45 cubic meter Containerized Mixing Systems (CMS). The equipment is multifunctional, easy to mobilize, and can be assembled efficiently on construction sites. Utilizing this equipment Sevenson can drill up to 140 ft. BGS.
Sevenson performs in-house solidification/stabilization treatability studies at its state-of-the-art environmental laboratory. The laboratory evaluates proposed site-specific treatment reagents and mixing schemes to confirm that they meet treatment objectives established for a project.
