Expansive & Hazardous Soil Remediation
Understanding Expansive Soil
Stabilizing Problematic Soil Conditions
Expansive soils—commonly rich in clay minerals like montmorillonite—can cause serious issues for structures, roads, and utilities. These soils shrink and swell with moisture fluctuations, creating instability that leads to cracking, shifting, and long-term structural damage. Found frequently in arid and semi-arid regions, expansive soil presents a unique challenge to engineers and builders alike.
At Orion, we take a proactive approach to stabilizing these soils through proven and engineered methods tailored to the conditions of each site. Our remediation solutions include:
-
Removal and Replacement of unstable soil with engineered fill
-
Prewetting to reduce the expansion potential before construction
-
Chemical Treatment using traditional agents such as hydrated lime, Portland cement, and fly ash
-
Moisture Control strategies to maintain consistent site conditions
Whether you’re managing swelling clay beneath a commercial build or remediating hazardous contaminants on a larger scale, Orion has the experience and resources to deliver safe, compliant, and cost-effective soil remediation.
Hazardous Soil Remediation
Addressing Contamination at the Source—and Beyond
Hazardous soil remediation involves identifying, isolating, and removing contaminated materials to restore safety and compliance on impacted sites. Whether the contamination is the result of direct spills, migration through groundwater, or historical industrial use, Orion has the experience to manage complex remediation efforts from end to end.
Our work spans contamination in soil, groundwater, surface water, and sediment, using a range of field-proven methodologies to stop the spread of hazardous substances and reverse environmental damage.
Each site is approached with precision—from site assessment and contaminant identification to removal, transport, and verified cleanup—ensuring compliance with local, state, and federal regulations while restoring environmental integrity.
Causes of Contamination
Contamination can result from a variety of sources, ranging from large-scale environmental incidents like industrial oil spills and hazardous waste emergencies, to gradual, cumulative degradation caused by pollution, sewage discharge, and industrial by-products.
Orion’s Remediation Services Address:
Groundwater Remediation
Treating contaminated groundwater, often caused by industrial spills, runoff, or landfill seepage. Remediation approaches may include physical removal, chemical treatments, or biological methods.
Surface Water Remediation
Removing pollutants from above-ground bodies of water using techniques akin to those for groundwater remediation.
Soil Remediation
Addressing contamination in soil to restore agricultural productivity and environmental health.
Sediment Remediation
Treating pollutants in sediments that accumulate at the bottom of water bodies, preventing long-term environmental damage.
The goal of any remediation effort is clear: to eliminate contamination, restore ecosystems, and protect public health. Effective remediation requires strategic planning, skilled execution, and ongoing monitoring to ensure lasting results.
