PDS - LES System.pdf

This product description sheet (PDS) is from TenCate, detailing the Geotube® LES™ (Lake Embankment System), a specialized geotextile solution for erosion control and embankment stabilization. The product is a low-cost, embankment erosion counter-measure system utilizing a small, nonwoven geotextile tube constructed of polypropylene fibers, which is filled with onsite sand or soil and strategically placed at the toe of an embankment. The installation process is simple, requiring minimal excavation, and involves placing the tube, driving stakes through an anchor flap, and hydraulically injecting sand or soil into the tube through self-closing ports. Once installed, the tube can be backfilled and vegetated to create a natural-appearing embankment.

The Geotube® LES™ offers comprehensive service including design and specification assistance, with the tube demonstrating robust mechanical properties such as high grab tensile strength (1.3 kN in machine and cross directions), UV resistance, and resistance to chemicals, alkalis, and acids. The system is designed to work in three stages: filling (container filled with dredged sand), containment (durable fabric allowing material suspension), and structural (serving as a structural mass that can be used for erosion prevention). The technical specifications indicate the system can be configured with various dimensions, such as a 1.5 ft height and 5.5 ft width, with an estimated weight of 950 lbs when filled with sand, making it adaptable for different environmental and engineering requirements.
