Product Introduction:
Sediment Bags are an environmentally friendly protective product specifically designed for soil and water conservation and sediment control. Their core function is to effectively block sediment particles generated in construction, treatment and other scenarios through physical interception and filtration, preventing them from spreading to surrounding water bodies or soil with the flow of water. At the same time, they have a certain drainage capacity to avoid water accumulation that could affect the progress of the project or the ecological environment.
The product adopts a modular design, with each bag independently formed and capable of flexible assembly, ensuring continuous interception while allowing for adjustments to the layout based on actual site requirements. In terms of materials, the product is guided by environmental protection, with the mainstream version using biodegradable non-woven fabric or high-toughness environmentally friendly polypropylene (PP) woven fabric. The former is suitable for short-term temporary protection (such as seasonal construction) and can naturally degrade without leaving residues, while the latter is suitable for long-term protection (such as long-term river channel treatment) and has excellent anti-aging and anti-wear properties. Compared with traditional sediment control methods (such as sandbags and concrete retaining walls), Sediment Bags are lighter, easier to operate, and have no risk of secondary pollution, meeting the dual requirements of modern engineering for "green construction" and ecological protection.

Product Applications：
1. Construction field
Site boundary protection: Laid around construction and road construction sites (especially areas close to municipal roads, residential areas or water bodies), it forms a temporary sediment interception belt to prevent construction dust and sediment carried by rainwater from polluting the surrounding environment, in line with the requirements of the housing and urban-rural development department for "construction dust and soil and water pollution prevention and control".
Foundation pit / slope protection: Laid around foundation pits or at the foot of slopes, used in conjunction with geotextiles, it can prevent soil erosion on slopes and guide rainwater to drain orderly, avoiding slope collapse caused by rainwater erosion. It is suitable for foundation pit excavation projects in building construction and road and bridge construction.
2. Ecological governance field
River / lake governance: Laid along the edges of water bodies in river dredging and lake ecological restoration projects, it forms a temporary or long-term sediment interception barrier to prevent suspended sediment from spreading to core water areas during dredging, protecting the habitat of aquatic organisms; it can also be used to reinforce river banks and reduce soil erosion on slopes.
Mine restoration: Laid along drainage channels or slopes in the ecological restoration areas of mined-out areas, it intercepts mine waste and sediment left behind, preventing them from flowing into surrounding farmland or water bodies with rainwater, and can be used in conjunction with vegetation restoration to accelerate the reconstruction of the mine ecosystem.
3. Agricultural and municipal fields
Agricultural soil and water conservation: Laid along the edges of terraced fields and in farmland drainage channels, it intercepts soil erosion from farmland and reduces the entry of fertilizers and pesticides into water bodies with sediment, protecting the agricultural ecological environment; it can also be used for slope protection in orchards and tea gardens to reduce the impact of soil erosion on crop growth.
Municipal engineering protection: Laid at the junction of construction and non-construction areas in municipal pipeline renovation and park landscape construction projects, it prevents construction sediment from polluting municipal roads or landscape water bodies; during heavy rain, it can be quickly piled up to form temporary drainage channels to assist in urban flood prevention.
4. Emergency rescue field
Temporary flood and sediment control: After sudden disasters such as heavy rain and floods, Sediment Bags can be quickly transported and laid to block small pipe gushes and intercept sediment carried by floodwaters, protecting villages, farmland or infrastructure; it can also be used for temporary protection at landslide sites to prevent the spread of sediment caused by secondary collapses.
Sediment Bags is a sediment control product focusing on environmental friendliness and high efficiency. It is made of degradable or high-toughness environmentally friendly materials. Its core function is to physically intercept sediment and prevent soil erosion, while also having water permeability to avoid water accumulation.
The product is lightweight and easy to fold, allowing for quick manual installation without complex tools. It is suitable for various terrains such as slopes, ditches, and river channels, and can be cut and spliced as needed. Compared with traditional sandbags and concrete retaining walls, it causes no secondary pollution, has strong adaptability, and requires simple maintenance.
It is applicable to multiple scenarios including construction site protection, river regulation, and agricultural soil and water conservation, balancing green environmental protection with practical cost-effectiveness.
