Abstract: A sediment containment barrier capable of functioning in an outdoor environment for 18-24 months or more, while offering full rebound to compression impacts even after exposure to rain, construction traffic, and other harsh elements of an active construction site. Through a protected central core of foam or air surrounded by a water impermeable middle membrane and outer filtering shell, the barrier is able to withstand being run over by construction traffic hundreds of times while rebounding to its original shape and more importantly maintaining its compliance as an effective dirt and silt containment barrier. Due to the filtering qualities and the embedded nature of the barrier, the barrier offers high flow, reduction in the ponding of water, the effective filtration of sediment and silt, and a lower height than conventional sediment containment barriers.

Abstract: A gravel bag manufactured from a single layer of a heavy-duty geotextile composite material (also referred to as “geo-composite”), said layer comprising a closure device resistant to opening as pressure is applied from within. The geo-composite material is formed by affixing at least two fabrics that together complement each other's performance. The overall structure allows for a single composite geotextile fabric that is low-slip, low cost, offers effective padding, has a high tensile strength, is puncture and tear resistant, and that has low elongation properties. In use, the single layer geo-composite gravel bag significantly outperforms all other single layer and multiple layer geo-composite gravel bags currently in use.
