GEOSTRUX™ geotextile tubes are produced using high strength woven fabrics which are manufactured to exacting standards by our in-house fabrication group. Once on site, GEOSTRUX™ geotextile tubes are hydraulically filled with heavily saturated sediment, sand or waste materials. When fully dewatered, the sediment has reduced weight and volume, allowing for more cost-effective material handling. In coastal applications, the structure is strategically placed before filling to provide cost effective shoreline protection or habitat creation.
