Publication number: 20020151241Abstract: In one application for remediating sediments, employing a geocomposite sheet eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers of the geocomposite. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction of pore water into the reactive layer or layers.Type: ApplicationFiled: April 4, 2002Publication date: October 17, 2002Inventors: Thomas Clair Sheahan, Akram N.

Patent number: 5766729Abstract: A bitumen-based waterproofing membrane is provided with an improved edge for sealing with a contiguous membrane to provide a membrane system with improved waterproofing characteristics. A bitumen-based reinforced membrane sheet is coated with granular material to protect the membrane sheet from ultraviolet rays. However, a section of the membrane sheet is first covered with a piece of protective tape which prevents any granular material from being deposited on the lateral section of exposed bitumen beneath the tape. The membrane sheets are then cut immediately prior to the tape or at the edge of the granular coating and then rolled up. Accordingly, the lateral section of bitumen which is covered by the protective tape is on the innermost part of the rolled-up membrane sheet. During installation, the tape is removed and the exposed bitumen or selvage section is disposed below an adjacent or contiguous membrane. Heat is then applied for an easy and effective seal between two adjacent membrane sheets.Type: GrantFiled: February 7, 1995Date of Patent: June 16, 1998Assignee: Polyglass S.p.A.Inventors: Luigi Zanchetta, Romano Zanchetta
