Does ERH cause soil settlement and can it cause building subsidence?
Settlement or subsidence has never been demonstrated on a TRS ERH project with the exception of some (expected) settlement in an unconsolidated municipal landfill. ERH does not dewater the site and therefore does not create void spaces in the subsurface that can cause settling or subsidence. All of our projects involving remediation underneath above ground structures require building surveys pre- and post-ERH to prove there is no impact to building structures from ERH remediation.
