Abstract: A reusable modified helium shroud soil vapor sampling system with an in-line helium detector includes a reusable, portable, sampling platform including a chimney attachable to a well head. The sampling platform includes an area for placement of at least one disposable three-way valve, at least one flow controller, at least one sampling can, an ambient helium detector, a line coupled to a helium tracer source, at least one vapor sampling line coupled to a soil vapor sampling well at a predetermined depth, and at least one purge line coupled to at least one purge source. An in-line helium detector is coupled between the at least one purge line and the at least one purge source, and a flexible collapsible shroud cover is configured to optimally seal a volume of helium between the shroud cover and the sampling platform.

Abstract: There is described a panel comprising: a backing layer having a back face and a front face opposite to the back face, the backing layer being made of polyester resin; an intermediary layer attached to the backing layer; and a surface layer attached to the intermediary layer, the surface layer being made of acrylic modified isophthalic gelcoat.

Abstract: A trench drain with a trench body and a grate for use with a flush-threshold or low-threshold shower. The trench body is rectangular, with a drain hole positioned in the bottom. Front and back flanges extend from the bottom of the front and back sides for an absolute flush installation of the trench drain to the shower body and the bathroom flooring. The trench body may extend under the shower walls on each side. A grate fits into the top of the trench body onto a lip or edge on the interior of the front and back sides. Protrusions may extend inward to help provide support and stability for the grate.
