Technology & Solutions

TRS uses state of the art technology and processes in its remediation services.

You can also click on the image at left to view a detailed diagram describing the Electrical Resistance Heating process.

Electrical resistance heating is an in situ, polyphase electrical heating technology that uses commonly available electricity and applies it into the ground through electrodes. These electrodes can be installed either vertically to any depth or horizontally underneath buildings, operating facilities, and in the presence of buried utilities. The technology is equally effective in soil and groundwater.

In response to customer feedback TRS has developed this brief explanation of the benefits of Electrical Resistance Heating (ERH) and where it is most effective.

The technology has been commercially deployed on over 90 sites since 1997. The TRS team is directly responsible for over 70% of these deployments in a variety of applications. These include: underneath buildings, in active facilities and with public access, for chlorinated volatile organic compounds at concentrations indicative of DNAPLs and fuel hydrocarbons as LNAPL, in most types of lithologies (including bedrock), and varying contamination depths (now up to 135-ft bgs). TRS has 100% client satisfaction on all projects and a dozen of the commercial sites have received closure.

Estimates are the best way to determine if ERH is right for each individual project, please use the online Technical Evaluation Form to receive a site specific proposal.
