Deep Foundations Testing Chamber

This testing system was installed at the Laboratory in 2006 as part of an effort to develop more cost effective deep foundation construction and installation methods. This unique system not only allows researchers to control soil conditions, but allows for the installation of instrumentation as the chamber is being filled prior to testing. Additionally the chamber provides the stability to safely perform excavations after testing foundations so that they can be inspected.
