Geosierra Environmental, Inc

GeoSierra is best known for our Trenchless PRB Placement technology for installing permeable reactive barriers (PRBs). In addition to Trenchless PRBs, we are leveraging our technology and highly specialized groundwater expertise to tackle other difficult groundwater cleanup problems such as source remediation in fractured bedrock, remediation of stagnant plumes in fat clays, etc. If you would like to know if a Trenchless PRB or one of our other groundwater cleanup solutions may be applicable for your site, we will be pleased to review your site data and provide you a budgetary estimate. For an estimate, download the “site data profile”, complete it and email it to info@geosierraenv.com.

GeoSierra’s Trenchless PRB Placement technology enables installation of PRBs at sites where trenching is not an option, i.e. deep PRB installations like the five we’ve installed that are deeper than 100-feet – or shallow sites with complexities such as beneath streets congested with underground and overhead utilities or even within active railroad right-of-ways like the five (5) PRBs totaling 3,650-feet in length we have completed at the former Kelly AFB in San Antonio, Texas. The Kelly AFB projects are the largest PRB project ever completed.

As PRBs have become to be widely accepted as superior to pump-and-treat systems, GeoSierra has been privileged to be selected by a number of Fortune 500 companies to design and install our deep PRBs at a number of superfund sites.
