Flood Control Bags
1.High-Efficiency Dewatering:
The permeable properties of geotextiles allow rapid water drainage while retaining solid particles, reducing overall volume.
2.Cost-Effective & Eco-Friendly:
Compared to traditional cofferdams or concrete structures, it offers lower costs, and some models use biodegradable materials, making them environmentally sustainable.
3.Easy Installation:
No heavy machinery is required—simply fill and shape on-site, adapting easily to complex terrains.
4.High Durability:
Resistant to UV rays and corrosion, suitable for long-term exposure in harsh environments.
Product Introduction:
Flood Control Bags are high-strength flexible containers fabricated through specialized sewing techniques, typically made from high-tensile, corrosion-resistant geotextile materials that can be either permeable or impermeable. These tubes can be filled with materials such as sand, silt, sludge, industrial waste residues, and other similar substances. Through natural or mechanical dewatering processes, the contents solidify into stable structures, enabling their application in engineering projects for water retention, soil retention, dike reinforcement, and environmental treatment.
Features
1.High Strength and Flexibility
Constructed with high-strength geotextiles, the tubes exhibit high tensile strength and can withstand significant pressure.
Their flexible structure adapts to foundation deformations, reducing the risk of cracking.
2.Permeability and Filtration
Permeable geotextile tubes enable dewatering of high-moisture-content materials, allowing water molecules to pass through fabric pores while retaining solid particles.
Impermeable tubes can contain slurry and prevent leakage.
3.Customizable Design
Dimensions, materials, and permeability properties can be tailored to meet specific engineering requirements.
Tubes can be joined to form various shapes, accommodating complex terrain.
4.Rapid Construction Speed
Filling operations are straightforward and require minimal time, enabling the rapid formation of water- or soil-retaining structures.
5.Low Maintenance Costs
Post-construction durability ensures long-term performance with minimal need for subsequent maintenance.
