Patent number: 7670082Abstract: Reactive gabion/geocomposite articles, and their methods of manufacture, for controlling contaminants in soil, sediment or water that allow the passage of essentially non-contaminated water therethrough. The articles and methods described herein utilize gabions, which are box shaped cages or grids (see FIG. 2) made of either steel wire mesh or plastic. In one embodiment, the reactive geotextile mats are lined on the top major surface with a gabion cage or grid. In other embodiments, the cages or grids surround a geocomposite containing reactive material. The gabion/geocomposite articles can be constructed in-situ (at the site of deployment) or remotely (on land or barge) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion/geocomposite articles may be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring.Type: GrantFiled: April 30, 2007Date of Patent: March 2, 2010Assignee: Amcol International CorporationInventors: James T.
