Innovative Use of Sliding Rail Shoring and Installation of Vertical Hanging Barriers

Sliding rail shoring has been in use for many years in the construction industry. While sliding rail shoring is not unique, the method by which we’ve employed it for soil and groundwater remediation is. Hemmera and Claybar have adapted and applied the traditional sliding rail shoring system to facilitate excavation of impacted soil and entrained groundwater along property lines and with adjacent underground utilities, all without the need to access adjacent off-site properties. In addition, we’ve used the system to facilitate excavation of impacted soil under building footings and in some cases even further under the building. Lastly, the sliding rail shoring system has been modified to be able to install a contiguous vertical liner directly situated on property lines. The liner installation method is unique, has been successfully implemented, is less expensive than traditional shoring systems, and addresses the often complex technical and legal issues of accessing off-site properties. The purpose of this talk is to review how sliding rail shoring is used to remediate impacted soil and entrained groundwater and its benefits and limitations. To illustrate the method, we will present a recently completed project where sliding rail shoring was used to excavate impacted soil up to 5 m below ground surface between two buildings where the distance between the buildings was only 10 m. In addition, we simultaneously used the shoring system to install a vertical bentofix lined HDPE barrier on the property line between the two buildings and then used the system to facilitate underpinning of the site building and excavation approximately 1.5 m under the building and 5 m below ground surface. To demonstrate its benefits, we will contrast the time and cost of conducting this work with traditional shoring systems, property line implications, and we will discuss the options and outcome if no shoring was employed.
