GEOTUBE^® Marine tubes are sausage-shaped systems with diameters ranging from 1.6 to 5 meters. They are hydraulically filled with a sand and water mixture, allowing water to be expelled through the textile pores, quickly forming a core for bund construction. These systems can be filled both in shallow water and onshore, precisely where needed. They feature fill openings and either tapered or flat ends for seamless lengthwise connections. Made from durable textile in black, they also come in beige for beach applications, blending naturally with the sand.
