A Stormtech isolator row profile connects to a catch basin or manhole via a twelve-inch minimum inner diameter to twenty-five-inch maximum outer diameter pipe set one and a half inches from the bottom of the chamber. The chamber is wrapped in a woven geotextile meeting AASHTO M288 Class 1 requirements between foundation stone and chambers, using six-foot wide strips for SC-740 and four-foot wide strips for SC-310. An inspection port is provided by the design engineer. The entire row is covered with AASHTO M288 Class 2 non-woven geotextile using eight-foot wide strips for SC-740 and five-foot wide strips for SC-310.
