TerraTherm - a Cascade Company products

Electrically powered and custom-fit heaters provide the most efficient and effective heating of each site. Our heating technology has been thoroughly tested, perfected, and proven.

Safe, reliable, and effective technology to treat your site. TerraTherm’s Electrical Resistance Heating (ERH) systems are specially engineered and designed to safely address a wide range of conditions that may be present at your site, including working in, around, and beneath buildings and infrastructure.

There is no room to learn on-the-job at a complex steam site. Our clients benefit from more than 20 years of experience in the design and implementation of Steam Enhanced Extraction (SEE), to deliver results safely, efficiently, and consistently.

Reduce your risk and liability by choosing our proven IPTD technologies and designs. TerraTherm has successfully treated over 135,000 cy of soil and sediment using IPTD and its patented TCH technology for difficult to remediate contaminants similar to PFAS such as PCBs, dioxins, and PAHs. Piles have been designed to treat as little as 50 cy up to 60,000 cy in one batch.

TerraTherm’s low temperature thermal treatment technology gives you a sustainable and less costly alternative to full thermal treatment. Low temperature thermal treatment gently heats the treatment volume to temperatures between 30 and 90°C to enhance biological and abiotic contaminant degradation mechanisms without the need for expensive extraction and treatment systems.

TCH is the only technology that can heat soil to temperatures greater than 100°C (e.g., 150 to 350°C) for treatment of high boiling point contaminants such as PCBs, PAHs, Dioxins, PFAS, and even mercury. ERH and SEE cannot achieve these temperatures or effectively treat these compounds.
